for dudes who have a nice computer, but still getting weird lag, and who have downloaded the latest beta driver from Nvidia.....what really eliminated the fps drops for me was
www.nvidia.com/Download/Find.aspx?lang=en-us
1. You can select Ultra settings ( if u have good pc )
2. DISABLE anti-aliasing ( u won't notice the difference since the AA in this game is small )
3. DISABLE SSAO ( wont notice hardly too much
4. Disable Uber Sampling ( it's a waste since it drops FPS even on the most powerful systems )
Let me know if it worked for u
ohh i thought it was on purpose it lagged like that because its such an annoying game
