Black ops 2 GPU frame issues

i get this frame stutter i notice it when i move my mouse left & right its never happen before & yes i my driver is up to date fucking hate getting that reply. i have a His iceq 7870 ALSO I SEE THE SAME ISSUE WITH OTHER GAMES BF3 & CS GO some i've played

Are your Dri... Just kidding.  Are you sure its a frame stutter issue, and not just an intermittent input lag of any kind? Because it spans more than one game. Hey this is completely unrelated, but my framerate went from 45 FPS to 70 FPS in certain areas if i turned DOF from High to low. And high doesnt really look any better, just different. is that normal??

i really don't know i put most settings on medium to low my mouse tins to stutter left & right when im moving it never happen before
