Guys, your PC specs are good, more then good to play FIFA 12 on high settings. Problem is in EA, they didn't optimize their game, they fu*ked up big time. I also have same problem. I removed crowd and put all my settings to low, with lowest resolution and still I have lags. Maybe there will soon be an official patch which will solve those lags, but don't take it for granted, cause EA never learn. Also, try solution with Fidel's Optimizer or use D3DOverrider.
