Hey, So, I read that Nvidia had allowed PhysX to be used with an Ati card. I figured I would install my old 8800 GTX to this system and use it for PhysX. Well, I have a bit of a problem here. I installed the 257.15 driver set which supposedly allows the use of Ati card for rendering. I set up a fake display as informed, but when I go to Nvidia control panel, PhysX tab isn't there. What am I doing wrong?
