So I’m running a GTX 670 and I was happy when I got it because I could finally use borderlands 2 and pre-sequel PhysX. But to my surprise it lags like hell. 15-30FPS in combat and its even worse in pre-sequel. I installed those legacy drivers and the one that everyone says works and I only got a tiny increase in FPS. Any help? I love physX and what it does but there is no way it runs that bad especially on a GTX 670.
