In any game that uses 2-dimensional rendering, (not necessarily a 2d-based game), I find that there is a consistent stutter happening approximately twice a second ONLY affecting the 2d part. Sometimes the stutter slows down the animation for a frame, and sometimes it jumps ahead a frame. Because of the forward-jumping, I suspect it is not a problem with my GPU being overloaded, but might have something to do with over/underclocking. I have tried resetting my graphics card, but nothing changed.
