I saw in the nVIDIA Forceware 91.31 release notes that there is a new extension named: WGL_NV_gpu_affinity It probably does the same as the Windows function SetProcessAffinityMask but for the GPU on SLI machines. I didn't find any documentation on parameters for that function. Does someone have some ?

I'm betting on that being used for things like HavokFX, where one GPU is used for physics and the other for graphics...

NVIDIA had suggested a while back that they would be opening up more direct control of SLI under OpenGL. My guess is that this allows just that.
