This is the second time I've had trouble with ATI Control Panel. In games, it causes my controls to gum up and become sticky. It's pretty hard to snipe if when you move your cursor, it randomly moves or waits 2 seconds to move...in the mean time you get killed.
It isn't a good feeling to be moving then take your fingers off the arrow keys and you still move for another second. It isn't lag, it's the computer. And really, it isn't the computer, it's ATI's forking retarded software.
You would think they'd fix it by now. Oh wait, they did--but then they broke it again 4 versions later.
