Q: What is ratGPU?
A: ratGPU is a free OpenCL ray tracing renderer. Currently it works for 3dsmax 2010/2011/2012 and Maya 2012 ( Windows & Mac ).
It also includes a benchmark.
 
Q: Which are the minimum requisites to execute it?
A:  It should work with any NVIDIA GeForce 8 (or above) or ATI Radeon 4XXX ( or above ) with almost 512Mb of VRAM.
The operating systems supported are Windows XP/Vista/7, Ubuntu linux 11.10, Linux Mint 12, OpenSUSE 12.1, Fedora 16 and MacOSX 10.6/7 by now.
 
If you use ATI card you'll need the latest Catalyst 11.9 APP drivers ( the ones including OpenCL ). Drivers prior to those ones may hang ratGPU.

If you use an NVIDIA card you'll need the lastest Forceware 28X drivers or above ( the 19X, 25X and 26X have several problems with ratGPU ).
Please, notice that there is currently a limitation that forces you to use the x64 application in a 64bits OS. If you try to run the x86 app in a 64bits OS it will fail !
 
Q: Screenshots, please !
A: Well, here are some screenshots showing the normal's output, ambient occlusion and reflection/refraction/Fresnel/caustics
