Vireo & GPUs (nVidia Optimus)
Posted: Fri Apr 26, 2013 7:43 pm
Apologies if this has been asked or answered before, still learning and a quick search here and the wiki didn't turn up an answer.
I'm using a laptop running Windows 7 with an nVidia 680m as my Oculus machine and am having difficulties getting it to use the proper GPU in conjunction with Vireo Perception. For example Mirror's Edge will use the proper GPU until I toggle Physx in the options to get Perception to hook in, after that it stops using the 680m and switches to the integrated graphics. Skyrim behaves the same way, with the Perception application open, running SkyrimLauncher.exe doesn't detect the nvidia GPU unless I force it to use it. In that case it then detects the proper GPU, but the game still won't use it when it runs (as confirmed by the GPU monitor).
If I don't run the perception application at all but instead just place the three .dll's into the games directory, we have the same behavior - only the Intel integrated graphics are used.
I've tried running the Perception utility as admin and assigned both its .exe and .dlls, and the game .exe's, to use the nvidia GPU in the control panel to no avail. As soon as it hooks in it the game switches to the integrated graphics and won't let go!
If anyone has any ideas or anything I could try I'd appreciate it! Unfortunately disabling Optimus entirely doesn't seem to be an option.
