Can anyone explain Gpu usage to me? When I play BF3, my CPU (i5 2500k) sits around 60-70% usage and GPU is at 99% usage, which is good. But now i'm playing F1-2012 and CPU usage is at 75-85% while GPU usage only at 65-75% usage. Why doesn't this game run at 99% usage? Isn't that ideal? Wouldn't I get more FPS out of the game if it ran at 99%? Another questions is why isn't running at 99%?
