So I'm playing mirror's edge and the difference between enabling and disabling PhysX is massive - mainly due to the fact that it's trying to use my CPU rather than my GTX 680 graphics card. Installing physx via winetricks made no change to performance so I have to ask: Is lack of working hardware physx support a result of lack of wine support or a lack of nvidia driver support? (I'm using 295.40 proprietary nvidia driver)
