This is an experimental win32 SSE2 build with CPU/CUDA support.


Make sure you have up to date drivers or you won't see the 'GPU' Device!

Tested with NVIDIA drivers 270.61


Have Fun!

Had the same issue while working on complicated scene and using nVidia GeForce 320M,
what kind of scene you're trying to render ? Could you try to render standard cube and see if that solves the trick ?

In my case I assume that at first scene was too complex to fit into 256MB of mem that GF 320M operates on.
Try it yourself

Can't find an edit button sorry.
I mean the 64 bit version of cycles does the same for me.

CPU mode works fine for me but GPU mode just gives me a black screen. The console reports
CUDA error: Out of memory in cuLaunchGrid(cuPathTrace, xblocks, yblocks)
Athlon x2 3.2
8800GTS 320
Vista 64
I've installed 270.61, Cuda Toolkit 4 64 and 32
The 32 bit SSE2 version does the same for me.
Any thoughts?

the same!
I did tests on the performance CPU and GPU
I realized that when you use GPU cycles is less than 35% processor use
And when using the CPU, processor using 90% -95%
Why not use processor cycles within 90% with GPU?

Thanks for the cycles.

You need to use it with Fresnel lower than 0.45 (0.15 is very close to glass).

Reflection isn't looking right, I'm using Glass BSDF with roughness at nil and Frensel at around 0.600 and up.

Nice... made a test (for info, downloaded to a x64 i7, Nvidia 1.5gb, 8gb ram).
Used this startup scene (with some new settings. Rendered with 100 Passess

Render with CPU: 1 minute 44 sec
Render with GPU: 40 sec

Can Cycles support Muti GPUs mode ?

does anybody managed to put a texture on to a material ?
what's the procedure?

This build is working on my system, but I have to test it more.

3.0GHz Athlon II X3
Windows 7 Professional x64
EVGA GeForce 460 GTX se

The GPU rendering speed is faster than the video demonstrations I have seen, but again I have just started to test.
Fantastic job so far!

Also, have you a lead on whats causing those UV problems?
19:18 May 3rd, 2011
Even faster :) Amazing!

I heard someone talking the other day about particle support, is there a trick to getting hair to work or is that not ready yet?

I updated my drivers to 270.61, but it doesn't work, heres the dump from blenders console:

Traceback (most recent call last):

from cycles import libcycles_blender as lib
ImportError: DLL load failed: The specified module could not be found.

My graphics card is the Nvidia GeForce GT 230M, its a mobile card.
