I have the same issue, PC version, windows 8.1, GTX980, i7 5820K @3.30GHz., using mouse and keyboard (hardware cursor on)For me It is more noticeable when moving the camera around slowly, rapid movements are very fluid.When on horse it is also more noticeable on slow camera movements. I have hair works off and shadows on high, everything else on ultra, and it runs fine most of the time just this jutter/stutter on slow camera movements and the occasional freeze while in the inventory, that bug is also a pain in the *ss.
