Hi!
In my experience, NV_gpu_affinity does not work correctly on WindowsXP either. The last working version of the drivers are Forceware 186.x All drivers above 190.x have a "broken" NV_gpu_affinity. So you might consider back-dating your drivers ;-) quoting an Nvidia engineer: "Sadly this is a known limitation with the new r190+ drivers. The limitation is that since r190, using GPU affinity on a window DC doesn't work anymore. The solution now is to use an off screen drawable for GPU1 and then use NV_copy_image to transfer the image data from GPU1 to GPU0. I don't believe this is documented anywhere either. In fact, I didn't even know about this limitation until today." . "wglMakeCurrent() should be failing when used with a window DC. If that's not happening, that's a bug."

The GPU affinity extension does only work for FBO's on these platforms. We're working with nVidia on resolving this issue.
