this problem has only just popped up for me, when I look around my screen stutters. when I approach a task group my frame rate drops dramaticaly. My frame rate used to sit on a solid 60 now its all over the place, look up and its 118 or higher it just seems unstable. When I look down or left or right it drops to slide show rates.
