5 is the highest I can go. It won't go above that. The normal map is 2048.

Some interesting things have been happening regarding GPU acceleration. Some people over at Luxrender have been experimenting with OpenCL rendering. http://www.luxrender.net/forum/viewtopic.php?f=21&t=2947&p=28569&hilit=opencl#p28569 I remember that there were some interesting elements of your CUDA implementation.…
Oh, nice... the new FW 196.75 seems to fry the GPUs! http://www.incgamers.com/News/21293/nvidia-19675-kills-video-cards http://www.brightsideofnews.com/news/2010/3/4/nvidia-retracts-whql-certified-gpu-killing-drivers.aspx The 196.34/196.21 breaks Optix... The 195.62 are old but seem to work ok.

The biggest file I could manage was 51k polys, with 420MB(setting 450 would crash xnormal) set in the…
