When everyone started complaining about input lag, I didn't experience it. Then 2-3 weeks ago, suddenly I did. Has anyone actually been able to solve it yet?
Do you have vsync on? Don't use ingame vsync, if you want to stabilize your framrate then use the vsync option in Nvidia or AMD CCC panel instead (and enable triple buffering too).
If itsthe same input lag I was getting, try running in windowed full screen. see if that helps. I had a hitching/stutter issue in addition to input lag, not sure if it was the same but may aswell try it.
