You can make it better by using you video card driver software to override in game settings for AA. I, for instance, use an ATI video card and use Catalyst Control Center to change AA settings and others to try and get the best looking game I can with the best FPS that I can. All you really have to do is alt tab out of game, change your settings in the driver software, tab back into game to see if it made any difference. On a side note, not sure if you know this but pressing crtl+shift+F turns on the in game FPS meter, you will see it in the bottom left hand corner.
