Now, I don't know if i'm just misinformed or I'm being held back some how.
I was under the assumption the 'activity' should be above 98% - if I'm overlooking something and looking like an idiot I would be very happy =)
You probably have Vsync checked in the game which limits the FPS to your refresh rate, i.e. 60 most likely. There's no reason for your GPU to push more frames than what your monitor is capable of displaying, so it's fine.
