Has anyone noticed this since the last patch (2/7) in addition to some performance issues. I don't mind a drop in fps, but even at a solid 60 fps my mouse movement went from fairly smooth with predictable acceleration to erratic acceleration with panning to the left or right feeling jerky rather than smooth. Again, this started happening probably about half of an hour after the patch yesterday. I just want to rule out something on my end vs a game thing.
