OpenGL GPU Affinity Checker


GPU Affinity Checker is a small command line tool that allows to know if your
graphics card is ready for multi-GPUs tasks. This tool lists all available GPUs using WGL_NV_gpu_affinity OpenGL extension. Actually this extension is available only on professional graphics cards like NVIDIA’s Quadro series. On a Quadro with 2 GPUs (Quadro FX 4700 X2 for example) or with 2 Quadro FX 5800 (one GPU per board), you can assign (using WGL_NV_gpu_affinity) each GPU to an OpenGL render context and thus do real parallel rendering. Now if you have a graphics card for gaming with two GPUs (like the GeForce 7950 GX2, GeForce 9800 GX2 or GeForce GTX 295), you can make WGL_NV_gpu_affinity available via software modification

I think I will add GPU Affinity Checker functionality in one of the next versions of GPU Caps Viewer
