So far I have had this problem which I know I am going to have trouble describing accurately with three games. Assassins Creed: Origins. Far Cry 3. Ghost Recon: Wildlands. With Origins it happened after a patch so assumed that was the cause. With Far Cry 3 I noticed after installing the game but assumed it was a driver thing being a 5 year old game and I have just reinstalled Ghost Recon after buying the DLC Narco Road. The issue is movement, there may be a nano second of lag when I move the mouse this means the view does not have its usual sharpness until I stop moving. I am currently reinstalling Crysis 2 a game I played a few weeks ago and which was perfect. Whether there is any relationship between the issues I am having with games and the Oculus Rift I installed at around the same time has crossed my mind.
