i have windows 8 and i been trying to get PhysX to work with plantside 2 and metro 2033 but it wouldn't work i have heard of people getting it to work some how
It should work regardless of your operating system. Can you give some more details on your video card, drivers, and the PhysX games you are trying to run?
Asks me to restart and I do so and load the game up and says enabled and nothing has changed
What do you mean "nothing has changed"? Are you looking for PhysX effects and not seeing any? Planetside 2 has light PhysX effects as opposed to something like Borderlands 2 or Batman Arkham.
Oh god I did miss read one of your posts I thought you were talking about enabling physx in game ill try to see if that works with the nivida control panel first
