I've noticed that I can't get my FPS in MW2 multiplayer to what I want it to be. I'm playing at 1024 by 768 LOW settings on the 2010 2.93 GHz i7, so I don't really see why it seems choppy on maps like Rundown and Subzero. Every second there's a slight pause, very short, but it's also very uncomfortable. Am I doing something wrong?
