[osg-users] WGL_NV_gpu_affinity

2008-12-24 Thread Ferdi Smit
Is WGL_NV_gpu_affinity no longer useful on windows? Because it is not used in the win32 graphics window. I'm asking this because even though I can open rendering windows on two GPUs and use them in parallel in two distinct processes (by having two screens, one for each gpu, just like in linux/X

Interesting Stefan, I didn't know that. So how would one achieve similar effect on non-quadro cards? Surely it must be possible to use two GPUs independently? If not, that means that multi-GPU systems are inherently broken on windows? Or can I setup truly independent screens in driver settings
