As the rest of you, my FPS is all over the place,very unstable. The FPS can range from 70-90 ( sometimes 100 at times ) then nose dive if I pan the camera around right down to 40 fps or less. I wouldn't be so irritated if there was a lot going on,but it drops when there is virtually nothing there. The other thing I've noticed when this happens is the GPU and CPU usages are low,so why isn't the game pushing my GPU to 99% like every other game does. I've posted these screenshot a few times, but I'm going to post them again to show the constant fps battle going on:
