Perhaps you´re right -- what is your hardware by the way?
i5 3570k, gtx 660, 8gb ram, game on samsung 840 120gb ssd (40gb free) + 1tb wd blue
Its not my hardware since i run bf3 smooth on 1080p capped at 80fps, but it might be some driver issue, if i change drivers and they are no good i can always switch back right
Or maybe some windows update has gone bad, but i disabled auto update ...
