NV PerfKit Context Creation Issue
I have recently downloaded the latest NV PerfKit (18.104.22.16842) and tried it on my new laptop with GTX850M (Win 8.1 64-bit).
Unfortunately, I have to report a problem in the initialization process. Namely, the function CreateContextFromOGLContext() returns NVPM_ERROR_INTERNAL (17) NVPMRESULT.
The result is the same with all drivers I tried (340.65, 340.52, 337.88 ...).
Does anybody have the same experience or any hint what might be the problem?
The reason is in the fact that 22.214.171.12442 version (and probably earlier versions also) of PerfKit cannot create a context on Optimus platforms.
It is a known issue. I'm crossing fingers and hopping it would be fixed soon.
