1. Install Forceware 258.96, do not restart.
2. Run the patch, restart pc.
3. No need to go to NV panel to do anything.
4. No need to create fake display.
5. Check GPU-Z, if PhysX is checked then it is working everywhere.
6. Keep it simple.
i thought i had to dedicate the card to physx in the control panel.
CUDA isn't enabled on GPU-Z though, is that a problem, or is that only needed if it is your primary card.
