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), the frame rate is cut in half on windows, while it is not on linux. So I'm wonder if rendering commands are actually still send to both cards. Driving multiple GPUs independently is a pain anyhow...
