» Blender 2.79.1 - Fastest build - 20/09/2017
Updated 16:59 July 19th, 2017
(15371)  1,127,318






Blender fastest build with CUDA support.







CUDA kernels:

2.0, 2.1,

3.0, 3.2, 3.5, 3.7,

5.0, 5.2,

6.0, 6.1


Requirements: Visual C++ Redistributable Packages for Visual Studio 2013.


About old GPUs and CUDA problems:


If CUDA doesn't work with your GPU, go to Render panel, and change Feature Set, from "Supported"  to "Experimental".Just keep in mind that "Experimental" means some things won't work as expected.




About the Contrib Add-Ons


The Contrib Add-Ons are now in a separated category called "Testing"







I've carried out render tests of different scenes using Blender's Internal Rederer, and comparing this to many other x64 (and even x86 optimized) builds, and renders were always faster using this optimized build, that's compiled right from the trunk, therefore without any cut-outs.


Tested on Windows 7 x64, Core 2 Duo E7500 running at default clock. (2.93 GHZ)


Please, test it in your machine and give feedback about its performance.

deps build: correct sndfile fix

Note 1: It requires Visual C++ Redistributable Packages for Visual Studio 2013 to be installed.

Click "Download", and check vcredist_x64.exe


Note 2: A small add-on is you can launch Blender from AN_Priority.bat (located in the same folder than the Blender executable).


This simply runs Blender with priority set to "ABOVENORMAL", and is useful if you have heavy tasks running in background, and want Blender to have precedence to use processor's resources.As stated above, the bat is just a small add-on: It isn't, in any way, the reason why this build is faster than the other ones.


Still, the render tests I've done were performed WITHOUT launching Blender with high priority. error increased as the curve got longer.

The blender version is 2.78. Please update to 2.79.1.
02:34 September 27th, 2017
I just can't download it! I click on download bar, but instead of downloading version 79.1, it gives me 78!
21:43 May 21st, 2017
Very good work. Its incredibly effective and speeds up renders by a lot. One issue I have is that appending a PBR shader will cause cuda issues. I can only assume this is because the base is running off of 2.78a-b? Seems like this issue isn't present in stock 2.78c Blender.
03:32 May 16th, 2017
Forget about previous comment, it is some issue with web hosting service provider - every download from Graphicall fail. Will try it later.
02:52 May 16th, 2017

is it still available to the public? I tried to download this version several times, both with Firefox and Chrome, but download fails every time when reached about 60-70MB.

Thanks for reply :)

Any chance of getting cuda 6.1 I can't render with my 1080
01:55 November 27th, 2015
Thanks for the quick response! I just downloaded and tried it, it works fine!

If it's still not working for you, please link me to a sample .blend file, so that I can test it here.

Best regards

No, the problem is still there after I download the latest build.

Below is the screenshot, I use the same file open in your build and the official build, all the setting remain default.

Hi, I've tried the last build (4c60aae) and I've found a problem: rendering a tree there is a wide white outline around the leaves and the picture is full of fireflies.
Compared the same scene with the official build (95182d1) and everything is OK (no outline, no fireflies). I could send the printscreen of the probes if I knew how to do it...
17:20 April 28th, 2014
well nope. actually it doesnt work
17:03 April 28th, 2014
nevermind. i renamed kernel_sm_35.cubin to kernel_sm_50.cubin and it works now.
16:59 April 28th, 2014
please do something about cuda kernel 5.0
i was using the kernel_sm_50.cubin from here: http://martijnberger.nl/file/2.70_sm50.zip and everything worked fine but in the latest releases i get this:
cuda error: not found in cuModuleGetGlobal(&cumem, &cubytes, cuModule, name)

is there anything you can do?

thank you.
02:00 February 9th, 2014
CUDA 2.0 support is the minimum requirement, 1.x is no longer available for new builds (support dropped in source code, it's not just a compile option). You can find out what your GPU supports here: https://developer.nvidia.com/cuda-gpus
07:21 November 13th, 2013
Joining the previous question about cuda 1.1 cause I can't get my 8800GT to work. Keep getting "CUDA device supported only with compute capability 2.0 or up, found 1.1.".
Also found a bug. When using shrinkwrap and target it on an object with subdivision modifier and then, in edit mode, trying to move some vertices of the target object with snapping to the surface turned on, you will get a crash. But this is actually a bug of the blender and not your particular build. I only post it here because blender bug tracker is closed until tomorrow.
05:20 August 29th, 2013
Are you still compiling with CUDA 1.1? Tried this build on my old Alienware with GTX 280m graphics cards- getting the "Cuda Device requires compute capability 2.0, found 1.1" even when using experimental mode.

20:03 March 20th, 2013
Dear Sir, could you please help this build with 32 bit (x86) ?, I have an old card (sm 12) and i have try to build blender cuda for old card but only resulting on error in my compiler, thanks in advance
17:18 February 10th, 2013
Dude your build rocks! My render speed tripled!

Thanks so much for posting this!
05:17 February 5th, 2013
nice job nick bishop looks like you fixed those vertices afterall
12:49 February 3rd, 2013
ok i think that the sculpt auto re-topology feature needs to support self intersection so you can dig holes through things because that's what I need also I think it needs to
clean up the mesh a Little when done currently it leaves some floating vertices and edges hanging around that are down right ugly and could be fixed with a simple script

All is good here. GPU rendering works now. Good stuff.
02:59 January 17th, 2013
Alb, That's fixed it and I can now render out with GPU GTX 660 TI and also I am also able to use rendered mode in the viewport without it being corrupted. Many Thanks :)

vitos1k: Using Cuda 5.0 here

Maybe I could try again, with 4.2 instead...But this way, I believe GTX 6XX will still be unable to render

Best regards
13:05 January 9th, 2013
someone told that yours builds works fine, while official buildbot and other built with 4.2 toolkit failed
I can't launch your builds, windows gives error about parallel configurations of the app
12:59 January 9th, 2013
I was wondering wat CUDA Toolkit are you using for building CUDA kernels?
Current trunk built with MSVC and cuda kernels built with 4.2 Toolkit are failing to render on GPU's with sm_20 compute capability.
10:31 January 9th, 2013
Hey, just an update, the same issue I had previously is still present. Just so you are aware.

10:44 January 6th, 2013
I only have a problem with this one, and the 2.64 version worked great.
00:55 January 6th, 2013
Alb, I'm sorry to say that it's only yours I get it with. There are a few error messages reported when rendering with GPU and they can be found here https://www.dropbox.com/s/qfgoh7r6mmucnfl/Blender%20GPU%20Error.png

Hope you can get it fixed as I really liked your builds
00:01 January 6th, 2013
Hey alb.,

I just downloaded your new build and the problem seems to still persist. With that said, however, it does not seem to exist in the other builds that I have tried it on. Let me know if there is anything that you want me to try to trouble-shoot. Thanks.

casvlaco, nessie and B-Rae: did you notice that problem with all recent builds, or only mine isn't rendering on your GPU?
06:12 January 2nd, 2013
I tried to render Mike Pan's Cycles render benchmark test (http://blenderartists.org/forum/showthread.php?239480-2-61-Cycles-render-benchmark) in cycles with the build and it will not render.

I simply get a black render result and an error on the display (http://i49.tinypic.com/34gpx7k.jpg) as well as some errors in the console (part 1: http://i47.tinypic.com/1zofais.jpg, and part 2: http://i49.tinypic.com/2ecgc9u.png). Both the Supported and Experimental settings yield the same results. I have also tried other files and the same issue arises.

My Specs are as follows:

NVIDIA GeForce GTX 670
32 gb of RAM
windows 8 - 64-bit

Please let me know if you need any more information or if I am doing something silly that can easily be fixed. Thanks!
01:12 January 2nd, 2013
Since i have the same problem as nessie, how do you post pictures?

amaranth: have you tried with default settings?
Go to "%appdata%\Blender Foundation\Blender", rename the folder called "2.65" to something like "2.65_current", and test if testing addons work that way....

After testing it, delete the folder "2.65" that was created by Blender, and rename back the folder "2.65_current" to "2.65"

nessie: Could you please post a secreenshot of your problem?

Alb, I am still unable to render with cycles using the GPU, although i can using the CPU. Also, blender no longer crashes when using rendered mode but the screen is corrupt
18:05 December 24th, 2012
hello, alb. love your builds. i have your 2.65.1 version, but recently whenever i install your updates, some of the testing addons won't work or CHECK in the preferences.

13:09 December 19th, 2012
Can anyone tell me if there is a reason why Cycles renders to a black screen (Blank) I have the GTX 660 TI. For some reason every cycles blend file I render is blank and when I try to run in rendered preview mode Blender crashes

13:23 December 15th, 2012
@Alb: Thanks, man. I've been experimenting with it, and have got some really realistic Cycles character hair going now. But I have to open the character from your build that I made into the other build, since it doesn't even have Collada import capability. But it is a great patch. I can't wait till that's in Fastest builds. Having Cycles hair (and eventually volumetric rendering...) will make Cycles a serious hardcore monster!
Thanks again for everything you and the devs do. Have a Merry Christmas.

That feature is a patch, and it's not in trunk yet...that's why I've not included it....

I'll look forward to create a new build with the patch when I have some time.

13:12 December 14th, 2012
Thanks, Alb, for another great build. I've always been faithful to your Fastest builds, but I have been experimenting with one of the new builds that has Cycles Hair Strand capability (although it does NOT have many of the great features that have come standard in your build since forever.)
Can you tell us when your Fastest builds will have the new Cycles Hair Strand rendering capability?
18:39 December 11th, 2012
is it me or the render_clay.py is missing?
06:59 December 3rd, 2012
Now the work cycles
I installed a new version of the drivers :)
But it is slower:
Using the file:
Blender 2.61 Cycles Benchmark rev2

Render time> 01:16.25

8723_blender-2.64-- 52,157 --- unified-contrib-add-ons --- --- fastest cuda
Rendertime> 01:10:58
06:25 December 3rd, 2012
Cycles cuda not work in my GTX670 render BlackScreen
Several versions of blender 2.64.9 do not work!
The older versions work ok
I have already installed the cuda tookit the most current drivers.
I noticed that the old versions have the render faster:
8723_blender-2.64-- 52,157 --- unified-contrib-add-ons --- --- fastest cuda
Compared with its predecessors that I downloaded

Why is this happening? Is there a way to solve?

17:07 November 11th, 2012
initiallly I thought 2.64 was slower than 2.63. BUT found that tile settings are very important, and now 2.64a is as fast or faster than 2.63a.

I tried your build 52016 and found it be comparable to 2.64a. Using Mike Pan's benchmark, 2.64a using 2x2 tiles renders in 43sec, 52016 default tile setting (120x67)
= 1:13, 500x500 = 48 sec.

How much faster is 52016 than 2.64a on your machine? What tile settings/pixel settings do you use?
Thanks for working on Blender! =)

13:36 November 2nd, 2012
Maybe it's true with Internal Blender Renderer but for me there's no difference in Cycles and only MinGW based builds are truly fastest ones. Maybe the maintainer of this build could try to make one?
13:54 October 27th, 2012
Hi, has anyone noticed that 2.64 64bit (all builds so far) are significantly slower than 2.63a (?) I haven't seen any posts, threads about it (except mine)
E.g. this build gpu render= 8min 15sec vs 2.63a = 6min 22sec using this benchmark http://benchmark.cd3dtech.com/Benchmark/benchmark.html

Crashes when trying to render.
00:21 October 7th, 2012
I've been using these builds for a while now and I just want to say how grateful I am for the work you guys put into this.

20:22 October 5th, 2012
great build and i wanna test it, can you make 32bit version???
19:32 October 1st, 2012

Trollvottel: Start Blender, and press Ctrl + Alt + U, and go to "System" tab.See if you can see CUDA next to "Compute device", and make sure it's selected, like so: http://www.pasteall.org/pic/show.php?id=38364

If yes, your card and its drivers are CUDA capable.Also make sure you're using Cycles Render engine.

Blender Render doesn't use CUDA.

Best regards
13:34 October 1st, 2012
Hi there... not sure I did everything correctly. Do I have to set up something to enable CUDA use? I compared this build to 1.63.0 without CUDA support. Performance settings identical on both builds; tiling set to 8x8 on both. i7 960 3.2 GHz, 8 GB.

Render times are only very slightly better. Starting frame of an animation now 11.82 secs, compared to 1.63.0 it was 13.65 secs. I must admit... I did expect much more... whilst having no idea really what to expect. :)
11:05 September 6th, 2012
Alb: Thanks. Yeah, I've been playing with different tilings. Haven't tried just putting it at one yet... I like this new .18. I know this is probably been in there a while, but I just learned that Cycles has a new camera panel specifically for working in-camera DOF. VERY cool. I'm test driving it now like I've never used Cycles before, seeing what else I missed... It's good stuff.
Snakesong: I'd try making sure you have the newest card driver, if you haven't yet.
16:43 September 5th, 2012
265 . alb3530 (builder)
MartianStories: You can reproduce the classic behaviour of not-tiled rendering by setting both X and Y tiles to 1, in Render Tab > Performance > Tiles

Snakesong: Up to now, it hadn't crashed for me.You can fill in a bug report in Blender's Bug Tracking page about this issue (that is, if it wasn't already reported)

Best regards
10:41 September 5th, 2012
Also have the problem that renders crash. With progressive at the end of the render, without progressive after first sample. I tried MartianStories fix, but it didnt work for me.. your build is not the only one doing this, so it seems to be some recent change in SVN that causes the crash.
22:10 September 4th, 2012
Oh. Okay, I think I got it, Alb. Sorry for the complaint. In the scene I've been working on I had saved it with a renderlayer node setup that I'd left with the backdrop checked. It was the node setup that was causing problems. I opened the file and unchecked "Use UI" first, then unchecked "use nodes" in the node editor. Now it renders F12.
Seems to render very fast. I think I like the new BI-like way it renders tiles instead of little Cycles sandgrains...
21:21 September 4th, 2012
This new one keeps crashing on F12 render, Alb. It's fine on preview render. For F12 I've tried several times, haven't gotten it to complete a render yet. Get's close, then spooges it.
08:06 July 23rd, 2012
only with this build? u tried the others?
04:21 July 20th, 2012
Its possible do in user preferences, using not only one gpu but two? In this build i cant see choice GT580 + GTS250. Thnx.
02:05 July 11th, 2012
Great build, works fine. There is one annoying issue in cycles: if you render an image with a gpu (220, 1gb ram), then it won't deliver the Z-pass. That is quite annoying when my gpu renders 3-9 times faster than my cpu. Please fix it.
00:24 July 1st, 2012

Same problem as Aralox, same GPU: GTS250
20:41 June 28th, 2012
Hi, sorry if this is a silly question, but would it be possible for this to be compiled for 32 bit windows?
I'm trying to use CUDA with my GTS250, but I get this error: "cuda device supported only compute capability 1.3 or up, found 1.1" using the latest official blender build (2.63a) even with 'experimental' turned on. You mentioned that this build allows cards with CUDA version < 1.3 to use GPU acceleration, so I'd love to be able to use it on my 32 bit machine.
Thank you! :)

05:50 June 9th, 2012
Can you include Freestyle, please. My build always crashes. :)
23:31 June 7th, 2012

u might wanna try rollling back the driver to 270.61?
no harm trying..

The latest nvidia drivers and cuda toolkit didn't help. My system is win7 x64 i7 920 gf 9600gt . any idea what can i do to deal with it.
Second thing that i'd like to know is that when i change exposure in render panel it starts to rerendering in older wersions render was continue

Hey again,

i think the precise problem is that the compositor doesn't updates! no matter what i'm doing, only the first ever calculated image will stay in the backdrop...

btw i'm a big fan of colouring and framing the nodes... Great idea :)
11:47 May 28th, 2012

It's amazing how fast blender is developing, but i have small problem :D

Maybe its just me (win8 64-bit), but i can't use the gorgeus new compositor stuff! Somehow none of the input nodes work correctly for me, the image node doesn't gives me an image, the renderlayer is empty after the render (in the UV editor i see the render in the "Render Result", but in the backdrop there's nothing but that white cross. Please someone help me? :D

I have lots of blender running without rebuke, but these new ones the only glitchty...

02:15 May 13th, 2012
I wanted to see how the different latest builds compare on my system W7 x64 i2600k not overclocked and GTX580

I first tried a BI rendering of a complex scene with many shadows and reflections :
1) r46561 by alb3530 : 16.80s
2) r46461 official 2.63a : 18.60s
3) r46534 by bat3a : 19.15s

Then tested the BMW1M Benchmark
1) r46534 by bat3a : 29.81s
2) r46561 by alb3530 : 35.28s
3) r46461 official 2.63a : 40.82s

Interesting results... and many thanks to all builders !
23:11 May 12th, 2012
anyway Blender Foundation just release official 2.63a build..

23:08 May 12th, 2012

hmm not sure about that, me no computing engineer lol!
but since now haven't have the support for Cuda 3.0 kernel,
it's good time to save up the money if u intend on getting either GTX 680 or 690

it's kinda meh if u buy either of the cards and found out it doesn't have the suppport for ur fav. apps/programs
like, u buy a Bluray player but there's no Bluray disc for ur fav movie yet.
11:51 May 12th, 2012

Thanks for the reply.

What i meant, in fact, was about the Cuda version : does 3.0 cards support other Cuda versions ?

(i have now just a GT 330m... but i envisage to buy another pc, just for blender... so 680, or why not 690, could be a solution... but only if blender can work with them !!)
07:00 May 12th, 2012
@Alikendarfen -
it just mean support for cards using 3.0 kernels (currently GeForce GTX 680 and 690 only) doesn't have much support yet,
since these 2 cards are expensive, most here in release builds/releases haven't got their hands on them

just wait for those developers who can afford these card to do their magic
00:08 May 12th, 2012
Tested on my GT 330m (yes... a small card, cuda 1.2, driver 296.10).

For small scene, all is ok and fast (3 times faster than CPU). But with a bigger one, windows crashes : blue screen.
23:28 May 11th, 2012
Thanks !

Just a question concerning Cuda support : "all but 3.0"... does it mean that 3.0 kernels could cause problem in the future (or for the official releases) ?
13:12 May 10th, 2012
ok FINALLY found a solution:

roll back to previous driver version..

for my case, 270.61

now real-time viewport rendering with GPU works fine (both Supported & Experimental)

tungerz: We could compile that kernel too, but one of the requirements is Cuda 4.1 toolkit, which has proven to provide slower render times...

Maybe there's some way to do compile using different toolkits i.e. 3.0 with Cuda 4.1 and other kernels with Cuda 4.0....

Please respond - anyone experienced such annoying bug:
After switching to another window type eg. from 3D to UV -> abnormal termination and...out.
OR (and thats interesting) after splitting the display horiz. and/or vert. and assigning 3D to the first window and UV to the other - crashes too, ....BUT: only when UV had been assigned first and stays as Upper or Right window, otherwise seems ok.

I have a problem with the wire. I checked in the properties of wire mesh, but there is a part of the mesh is visible.
I have a GTS 250, I checked experimental GPU, but it is "out of memory" or the texture is black, is it still called Cuda 1.3 (my cuda is 1.1). This is in the window, or rendering. Yet it works with a simple cube to boot windows ...
For the stage of the BMW I can enable rendering to the window but I can not make the scene ...
In the render if I put on the display image editor, in rendering if I press the escape key blender crash ... (all versions since BMesh)

10:57 March 3rd, 2012
Actually I take that back, I don't need to select "experimental", Blender uses the GPU with "supported" as well. Until I updated my drivers I didn't have the option to select GPU from the drop down in the render settings and I didn't notice because I switched to "experimental" as I was updating drivers.
10:46 March 3rd, 2012
Im running this on a laptop with an Nvidia 560m GTX, win 7 64 bit. What I've noticed is no difference between using the GPU or CPU, whether I select CUDA or OpenCL in user preferences. However if I change to "experimental" feature set in the render settings, then select GPU as the render device there, it renders nearly twice as fast.

It seems to me that it's not actually using the GPU unless I select "experimental" feature set, just in case anyone has the same issue.

I have the very latest Nvidia drivers, released on Feb 21 2012

Hi anyone,

I got this to see if I could get Cycles to run on my GPU (Nvidia NVS 4200m, CUDA 2.1) but it only shows OpenCL in User Prefs (and that fails because version is only 1.0).

Does anyone have any suggestions? Is there a problem because my system has Optimus? (Intel integrated graphics+Nvidia NVS 4200m) I have set Blender to always use Nvidia...

Sorry that I've missed the latest changes in the Blender builds about my problem the last time I've posted, I missed the new options on User Prefs from

I keep trying to get this figured out. I can't seem to get layers to work in Cycles. From the release logs and bug fixes, this looks like it should work. I downloaded rev. 43973 and I still can't seem to get objects on different layers to render separately.

Could someone set up a scene with three cubes, each on three different layers, and try to render that? Maybe post the file? From what I can tell, this should work and you should be able to render separate layers out just fine.

09:24 February 7th, 2012
Thanks for the effort. It is my first trial with the multi GPU mode with Blender, and it doesn't behave as I expected :
The preferences allow the use of one of the available GPUs, or all the GPUs, but it is not possible to use Two of Three available GPUs for example. I have one GTX 260 for display, and Two GTX 580 3GB for rendering, and I can't use the Two GTX 580. Except if I select all GPUs, but the rendering time is equal or worse than with only one GTX 580, and I think that the availlable memory amount will be the amount of the weakest card, so I would like to use the two big cards and exclude the GTX 260 (like I do with Octane). I tested with Cuda. OpenCL gives only a black screen.
My config : Win7x64Pro. IntelQuadXtreme9650.3GHz. 8GB RAM. One GTX 260 for display. Two GTX 580-3GB for rendering, in a Cubix-Xpander Pro2.

@alb3530 - it occured to me that maybe I'd see if passes render with CPU and guess what, it worked. Still, it refuses to deliver them with GPU on my GTX460SE and CPU rendering is dead slow compared to GPU. ;]

your builds are great, even the first time I downloaded... but it becomes slow on cycles, mine is gtx460 the other builds have faster renders... please just bring back the old settings for cycles, coz i think it's better to select manual than automatic... thanks and more power to your builds...
05:38 February 3rd, 2012
Your builds always worked fine for me( thanks a lot!), but the last ones (till 5889) got very slow in rendering with Cycles (gtx560ti). As other builds (a.i. tungerz) at the moment are a lot faster, I guess something has changed in your build. 5740 was the last one for me with fast rendering.

14:09 February 2nd, 2012
I just wanted to throw out there, in case anyone else had this problem, that on older GPUs with older CUDA kernels, you have to set the "Feature Set" option to "experimental". I'd searched for days for a resolution to the "error|cuda device supported only with compute capability 1.3 or up, found 1.1" issue, and finally found it in the middle of all these posts. Maybe add this detail to the top of the details section of the build information?

My blender works again. All is well with the world. Thanks to the devs and all you guys who are "just putting together builds". As far as I'm concerned, you could all be saying "I'm just a brain surgeon- I didn't actually create the brain"!

@alb3530: thanks for Your time nad effort, it's indeed a weird way of going thru it but if it works then I need do the same (as soon as I'll realize what exactly should be done with theese virtual machines;) but anyway...I can enter User Preferences but choosing 'System' tab results crash. I've tried some builds (including official 2.61 and Yours) before moving None/CUDA/OpenCL option menu from main interface Render tab to User Pref.->System and all working good. Tried to save as default the Supported or Experimental Cpu/GPU combnation but none has worked. The very first builds with the 'new' none/cuda/opencl menu have worked perfectly from what I remember. Maybe it's sth strange with default set on that 'new' menu in current builds? I have GTS 250M - not so popular mobile geforce model.

I could reproduce (and fix) this problem, but in a odd way....

1 - Started my machine from a virtual disk (Containing Windows 7 x64)
2 - Started Blender, set Geforce 9800 GT as the compute device in "User Preferences"; and saved settings;
3 - Turned the machine off and started a virtual machine with the very same virtual disk (Given that virtual machine can't see PCI devices, so the GPU is unavailable to it).That simulates the removal of the card.Maybe changing the GPU model would cause the same issue;
4 - Went to Blender "User Preferences", which caused blender to crash instantly (exception code: C0000005)
5 - Started Blender again, and loaded factory settings.After that, I could open all tabs of "User Preferences" screen.

This build stops rendering on my machine at random places, sometimes at the very beginning of render, sometimes well after several hundred or even thousand passes and returns the following errors in the console:

CUDA error: Unknown error in cuCtxSynchronize()
CUDA error: Unknown error in cuMemFree(cuda_device_ptr(mem.device_pointer))

The second line is being repeated about ten times. After these errors, GPU and memory clocks are severely set back, like it was messing with a driver in some way, and they won't go up upon next render, or even launching stable build. I have to reboot my PC, maybe reloading video driver would help, but didn't check it.

05:01 January 27th, 2012
@alb3530: same problem with your r43736
04:47 January 27th, 2012
@alb3530: Tested with nearly the same revision. Your r43704 and from builder bot the r43705 both win7 64bit.
- Scene with default cube
- switch render engine to "Blender Game"
- Press the button "render" -> "standalone player" -> "Start"
Than there should be the standalone player coming up. In the build bot version it's ok. But in your version the player doesn't show up, but is running without any window.
You have to kill the proces "blenderplayer.exe" to reactivate blender. Until this blender seems frozen (is waiting only to the ending of the player)
Will try your r43736 now.

You need to put Ctrl+Alt+U and choose 'System' where all CPU/GPU oprtions are (left/bottom corner).
@alb3530: I've posted recently on bat3a x64 thread same issue: from 2~3 weeks till todays builds I cannot fully use Blender and Cycles. Blender crashes when: with Cycles activated I click on 'Render' tab in standard right panel, press F12, press Ctrl+Alt+U and click 'System' tab ->all crashes related to CPU/GPU/Cycles. I have all MSVC++2008 installed, latest nvidia drivers, Cuda 4.1 toolkit. What can cause the problem in Your opinion? Older Cycles builds works.
23:26 January 26th, 2012
Why there is no option to choose the gpu render device ? In previous versions it worked correctly now there is only supported and experimental both CPU


When it would be fixed or can I do it on my own

03:41 January 26th, 2012
Thak you for your builds.
There is a problem with the new "render" -> "standalone player" -> "start".
The player will not be visible, it is running in background and blender looks like frozen. (it simply wait that you end the not visible player)
So you have to kill the process with task manager.
I have tested this version: http://builder.blender.org/download/
And there the player is working fine. So it's a problem with your build.

Hi thanks for your great builds!

Cycles GPU rendering (CUDA) on my GeForce GTX 560 Ti always worked, however in build 43575 I now get
CUDA error: Invalid value in cuMemcpyHtoD(mem, host, size)

It shows up in the viewport after the "Building BVH..." phase and on the console. Happens also when rendering the scene with F12. CPU rendering however is fine. Seems to be independent from the scene (happens with default cube also).

NVIDIA driver version is 290.53, but I didn't change the driver since testing the build before this one, where CUDA rendering still worked fine. I am running Windows 7 Home Premium SP1 64bit.

Is anybody experiencing the same problem?

Best regards

@AlexDS: just go to render settings tab, first ctrl+alt+u ->system and there in left-down corner choose Cuda/what card You have. Then go to standard panel and in render type settings switch from 'Supported/GPU Compute' to 'Experimental/GPU Compute' as GTS has older/unsupported from some time version of Cuda kernel.
...btw what the DS in Your username means?
05:12 January 14th, 2012
going in User Preferences -> System, done it now ,set Compute device correctly.

i have GeForce GTS 250 1.1 Compute Capability

in system console is says " Cuda device supported only with compute compatibility 1.3 or up, found 1.1 "

" it is recommended to use a GTX 4xx or GTX 5xx card (shader model 2.x), since only those are likely to give good speedup, earlier cards are often slower than just using the CPU." http://wiki.blender.org/index.php/Do.../GPU_Rendering

with my GTS 250 1.1 computing i rendered at twice-speed faster (when it worked) than with my i5 720 4-core CPU...

does it means that form now on i won't be having gpu rendering on my machine ?

As for the C++ Runtime, I have downloaded SP1 (I wasn't aware that there's any) and this problem seems to be gone.

As for the display driver issue, it's probably geometry-related. When I work with the same file, switch to another layer containing some simple meshes and then turn on the Rendered View, it's OK. When I change layers back, it usually works (reluctantly, though - it's a massive architectural file, roughly 3×3 km, with probably a few hundreds of buildings), but does crash sometimes. I'll post a screenshot of error and the console.

It regularly gives me a C++ Runtime error, when I switch to 3D View from Node View. I have to open a duplicate window, to be able to edit nodes. Sometimes, a mere click in the icon for changing window content, when in Nodes View, gives this error. Blender crashes in this case, of course. I'll check, if updating C++ runtime libraries (if there are any updates?) alleviates the problem.

Also, for particularly geometry intensive scenes, it crashes and returns an error that Nvidia OpenGL driver timed out. Not sure if it's driver, or implementation related. I'm on GTX 460 SE, recently updated drivers.

Hey alb3530,

yeh so basically I was having this problem of when solving a track, the solve would give an error value of 500-2000, and it was unuseable. Submitted a bug report and nazgul replied saying it was a problem with c-make and that it would be fixed in revision 42309, as stated here:

"Fix #29469: Latest motion tracking not working.

It was error in CMakeLists.txt caused by automatic bundling script which
expanded variables instead of substituting them as-is.

Fixed both of bundling script and CMakeLists.txt"

He also refered me to the official build bot build which i downloaded, which works. So making sure that it was past revision 42309, i downloaded this build, and it seems the fix has not been effective . If you can't find the solution, ill submit another ticket for nazgul and notify him that it was not effective.

ArekBulski: I've tested other builds and the same thing happened....sorry, there's nothing I can do.What I've succeded to do was rendering your scene in a lower resolution, maintaining everything else the same....

Take a look at nvidia support page:


ArekBulski and evan3585: The objects you model using older builds are meant to be forward-compatible, but the opposite is not true.

If you model something using recent builds, you probably will have problems related to dimension and distance of objects if you open the blend files using 2.60.0, for example....

This isn't a specific issue of my build: it's related to the development cycle.

ArekBulski: I suppose you're getting "Display Driver Nvidia Windows Kernel Mode Driver Version 285.62 stopped responding and has successfully recovered."
It might be related to the nvidia driver/card, as I've already heard a lot of people with this problem, also in nvidia forums.....I even found a Blender user speaking about this problem....
But, I remember when the first Cycles build was released, I had that problem when connecting/disconnecting nodes in a given setup....I'll take a look at your .blend file to see if I can reproduce it here...

I find this particular build problematic. For one, the .blend I made with this version seems corrupted when I open it with your older builds. Objects are moved around in a weird way. For two, rendering starts nicely but fails at some point with some generic "OpenGL driver bla bla failed" message. I am using Cycles with CUDA. Rendering within viewport works fine, only the proper rendering fails. Also rendering with CPU works fine.

Here I uploaded the problematic .blend and screenshots, anyone feel free to mess with it.

Oh, alb3530, thank you for all your builds. :)

Edit :

all of my CPU works together computing the subdivision surface of my cubes (not only 1 cpu 100%)
03:59 November 27th, 2011
Yep, first thanks for reading :)
I ll try to explain with my bad english:
- add a subsurf modifier on the default cube
- Open your CPU inspector
- Press Alt + A in blender to launch animation
- duplicate your cube
- Your fps will go down faster (depend of your CPU), you can set the fps to 60 to see the affect faster
- when your fps begin to go down, watch your CPU inspector
- You are "out" of cpu, but only 1 cpu is working at 100%, others are about 5/10%

- I tried with other build (OpenMP SSE2 build for windows 32b, here on graphicall), and my fps is really better with the same scene
- all of my CPU works together computing the subdivision surface of my cubes (1 cpu 100%).
- Gain is something like 300% faster in viewport for me

Thanks again

Load up this build,

open video file.

leave it at 250 frames for the scene, just for testing purposes, do a "detect features' and then track all markers for 250 frames. got around 20-50 tracked markers. Set camera data (nikon d7000, 24mm, set for tracking as well as scene camera) . add camera solver function to scene camera. select A and B frames. solve (some times crashes, not new) --- result is massive error with scene camera barely moving.

** just tried with default camera settings, this time the camera actually moved, although still had severe problems (jumping).

^ tracked on KLT.

Tracked this same footage in previous Tomato branch, no problem.

alb3530 :
yes actually, I tried this twice when I saw the comments bellow mentionning that issue... I did exactly what you say C:/BLENDER/blender.exe
still have an error... but not the same one !! lol

here is the console error :

openCL build failed : calcCompile failedError : Creating kernel kernel_ocl_path_trace failed !

Dobz: is OpenCL working in your machine using this very build?

tek5828: can you please share the .blend file you're having problem with?If not asking too much, can you explain your problem with m5ore details?

cobalt31: make sure that full path to blender.exe doesn't contain any spaces on it.It should be something like C:\BLENDER\blender.exe and not like C:\BLENDER 2.60\blender.exe
02:21 November 23rd, 2011
Hi... just tried out to put the blender directory directly on C: (to avoid the spaces in the exe path) didn't work... the kernel error still occurs

thanks for the suggestion though... I'll just wait and see
00:51 November 23rd, 2011
Just to let you know, unless i am doing something wrong and the process for 3D solving has changed in the tracker, but it doesn't work (KLT or SAD), tried on footage i have tracked in previous versions of tomato 64 bit, no work. tons of great markers, using SAD and KLT. What happens is after solve, play through, the camera rotates a bit on its position but has no 3D movement. , aswell, getting massive average error (130 to 595919235) , on this particular footage on old tomato, I was able to get a low error of 0.2 ! now no worky, This is r42051 btw, just downloaded latest. Thanks
10:03 November 22nd, 2011
Dobz - I tried what you suggested and it seemed to give me a different error now. The console showed a kernel error when I tried running it from a directory w/o spaces in it.

To all who helped - Thank you very much for all the responses, I'm assuming this error thing is about Cycles being a work-in-progress feature so I'll just watch out for any future fixes for it (or better yet, switch to an nVidia card soon...need to save up still though XD).

Thanks for your awesome efforts,
05:34 November 22nd, 2011
@alb3530: Ok, found the changing option, stupid me ;) . But the only change is, that with GPU rendering my system totaly starts lagging, thread detection stays with the 8 cores and preview rendering also has the same time it takes to render an image, just with GPU rendering I can't work with the maschine anymore, because I get a dia show. With CPU rendering I can work nicely. Thx again...
05:13 November 22nd, 2011
@alb3530: I have Nvidia Cuda Driver 285.62. On Gpu-Z it says 48 shaders, if that's where it states the cores, while I know the amount of cuda cores from the specs-sheet from Nvidia, where it states, that the GT330M has 48 GPU-cores. In this build I can't find the option to change between CPU and GPU rendering, it used to be under "performance" in the render option panel, or am I misstaken? I still only get 8 cores, so I'm guessing it's getting the hyperthreaded cores from my quadcore i7 CPU. Thx in advance again...
04:41 November 22nd, 2011
To everyone with OpenCL issues: make sure Blender is in a path that does not contain any spaces. This is a bug that is in the bug tracker and is hopefully being worked on. Alternatively if you have an NVIDIA card, just use CUDA to avoid any problems with OpenCL.

brektzar - i tried these following AMD Catalyst versions and found no luck with them:

10.5 (5/26/2010)
11.1 (1/26/2011)
11.5 (5/9/2011)
11.7 (7/27/2011)
11.9 (9/28/2011)
11.10 (Latest - 10/31/2011)

all of them gave me the same error and console message..
*I used Phyxion's driver cleaner to clean the drivers before installing another driver.
CPU render works..I'll just play with that for the meantime..

More power,
18:27 November 20th, 2011
brektzar - Updating the drivers didn't work, I haven't tried rolling back though. I'll do that later today. Thx for the suggestion. ^^
16:13 November 20th, 2011
It works great for me, but i have Nvidia, could it be a driver issue?

rhui- have you tried updating or rolling back your drivers?

Hi, I tried using this build today and I say it's really great! Although I have this problem, I couldn't use Cycles when I switch the Device from CPU to OpenCL GPU. It only gives me a black output, pitch black.
Is there anyone here who have the same problem? Or better yet is there anyone here who solved the problem already?

Thx in advance! :)

Speroangelus: It seems like your drivers are very outdated, as the latest version is 285.62....

You might want to go to http://www.geforce.com/Drivers and update the drivers....

Also, what application are you using to check CUDA Cores?Is it GPU-Z?

brick: Try to download now and let me know...If even so you can't, I strongly sugget you to contact your ISP, as you've stated you can't download the file even using a proxy server..

For all: there seems to be a problem with nodes, where you actuallty can't add nodes, it doesn't matter the context you're in...Scene, material, etc....

Lets wait it's fixed soon, cause it can be of no use if you're going to work with nodes in your current project....

And what is the card and driver you are using?

04:56 November 14th, 2011
I have notebook with a Cuda graphicscard, that's supposed to have 48 GPU-cores and an i7-CPU quadcore (emulated 8 cores).
When I use autodetection for Cuda I still only get 8 cores, could it be that only my CPU's cores are detected instead of the GPU's.
I've had this with every build of Cycles I've tried so far.
Has anyone an idea that might help me?
Thanks alot for these great builds though love it.
Thx in advance.

Yeah, it runs GPU now, and has all the usual snazziness we're used to in BI Fastest builds. I really love this. Now I don't have to have a Cycles and a BI anymore. Just ONE Fastest.
Thank you, Alb.
And it's got OCEAN SIM!!! :D
22:40 November 13th, 2011
would it be possible that your builds resulted being faster than any other optimized build on tests you have done on "your machine", because they are built on "your machine"? therefore the build is optimized for your hardware? :)

kalifrago: I'll investigate...But, still, the OpenCL support is incomplete

MartianStories: I'm adding added experimental CUDA support to this build right now...please test and let me know..I've tested with a simple render and it seems like it's working.... ;)

Best regards
14:34 November 13th, 2011
Hey Alb, I've always loved your Fastest builds and I'm really excited to see you putting Cycles in them (I've always looked forward to having a Fastest Cycles.) This is very exciting stuff, and it was only a matter of time.
However, your Cycles Fastest is NOT THE Fastest. That's because there is no GPU CUDA rendering here.
You make a Fastest, and make it so that NVidia Cuda cards can run on GPU, you'll have a smash hit on your hands. And if you apply all the little tricks you've done to BI to get your Fastests, you'll have an army of Cycles addicts like me sending you love poetry.

Perform a test render;

Also how come no CUDA?
14:15 November 12th, 2011
Sorry quys!

I am not very good using Cycles yet and I just made little mistake.
I didn´t know that you can´t create or upload new image in Edit Mode if you are not added Texture Coordinate node to your object.

I can create new image in Object Mode, but I can´t do it in Edit Mode to specific object without adding Texture Coordinate node in Node Editor.
In blender Internal Render this was posibble.

Hopefully you get my idea =D

i think it would be cool if he made it like the bat3a builds they have everything..

lux render, yafaray and mitsuba exporter.

along with all the contrib and external addons.

this one..

18:04 August 21st, 2011
hi, if you look at my build here: http://www.graphicall.org/82
It includes the External scripts & some more stuff.
Basically it's your build with the extra scripts & file structure added.
If you can contact me on irc freenode #blenderpython
I can help with issues that sometimes arise with the scripts/modules or any other info you may require. :)

10:29 August 18th, 2011
hi, could you please add the contrib scripts into a folder 259/scripts/addons_contrib.
this is much nicer than all the scripts in the one folder.
22:40 August 17th, 2011
Mmmmm.. add-on's !!! :)

19:39 August 15th, 2011
would be cool if you started putting the contrib and extrenal addon scripts into your builds

and adding lux render, yafaray and mitsuba exporter.

Maybe have 2 builds "fastest lite" without all the addons.. and

maybe something like "fastest complete with external addons/lux, yafaray, mitsuba exporter" or something :)

(it would basically be like the nice bat3a's builds, just with a faster blender internal render,
would the build optimizations make external renders faster as well? hmmm dont know)
19:22 August 11th, 2011
It does render faster. Nice work!

A few percent is nothing... Limit of CPU is reached.
Blender has to be OpenCL entirely - composer, rendering (Cycles), animation playback and so on. Graphics card MUST accelerate calculations.
