WGL_NV_gpu_affinity

OpenGL OpenGL: Advanced Coding

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?

2

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

3

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

4

do you reckon?

5

It probably involves a single function call like
wglSetGPUAffinity(integer)

and

glGetIntegerv(GL_GPU_COUNT_NV, …)

6

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.
