I look at the release note of the new NVidia driver (91.28 Beta) and I realize they add a new extension:

The following extensions have been added:
• WGL_NV_gpu_affinity
Anybody has information about this extension?

something to do with SLI, I shouldn’t wonder.

I can imagine it’s about SLI, but I’m sure some NVidia guys have a lot more details about this extension.

do you reckon?

It probably involves a single function call like


glGetIntegerv(GL_GPU_COUNT_NV, …)

Yes, this extension gives applications more control over SLI on Windows. We are currently beta testing this with registered developers. Please contact Nvidia developer relations for more information.

Simon, will it also be aviable on linux? If so, when?
