  1. You may have turned it off in the Nvidia control panel. You need to right click the desktop and click on "Nvidia Control Panel", there will be a tab on the left that has a PhysX option, and make sure to enable it.

    ill check that when i get home, but why in the hell would nvidia have this turn off when i have those cards install.. lol :non:
  3. I do not know why, usually it's due to user error :P It's the most logical reason it's not recognized in game.
