Hey guys. I'm wondering how to disable the nvidia control panel from making one of my cards just for PhysX use. I want to have full SLI and not one for PhysX and other for horsepower. And I don't want to make my CPU handle the PhysX either. Thanks for the help.
Two things you can try.
1) Look up simple code lines for the game you are playing and see if you can turn PhysX off in that application. One example that I use myself is "GPUphysics = 0" under "rendering" preferences in Planet Side 2 (because hundreds of explosions and people would be death to my GPU.) (You would set Physx to GPU then disable via game code in useroptions.ini
2) Uninstall PhyX (not recommended) because it could cause compatibility issues, however if it did mess up, just reinstall the current drivers and it will fix it.
