HI, i have a problem with Nvidia PhysX. i have ATI 6770M and problem is whenever there is a game that requires PhysX the lag when particles start flying around is enormous. i read about moddified drivers but cant seemed to find any newer that will work. i played mirrors edge and started noticing this problem, but there you can switch off and is fine. but now im playing binary domain and there is no option for this and when big fights start the game lags tremendously. can anyone help me with this problem? thanks.
