I'm not sure if this is a bug but it is really frustrating to deal with from an fps gamer's perspective. The game seems to have a mouse deceleration that I can't get rid of. I have tried disabling mouse smoothing as well as running as administrator. If I slowly move my mouse to the edge of my mouse pad and then swipe back quickly, in most fps games I would return back the the original position, but in DAYZ I go about half the distance back. This makes combat really inconsistent for me and I am sure a lot of other people. {F1508420}
Edit: I remember another developer for a different game had this issue and they fixed it and told me that the reason why it happened is because they were limiting the rotation speed per engine update on the players camera. Maybe that could be why.
