In addition, I'd also been making use of the option to disable fullscreen optimizations by using the check-box on 'csgo.exe' itself, but as of late have become uncertain if it's truly the best idea to do so? when I choose the Use Nvidia color settings option, I feel there's a bit less input lag & the game feels somehow more responsive? and in a way, I feel by leaving the colors to default, the game feels smoother & overall has less tearing or distortions when moving around? I have a monitor (AW2518H, to be exact) that has an ICC profile that comes installed with the monitor's drivers. Yet one thing that I've been uncertain about is the color options found under the 'Change Resolution' tab of the NVCP, where you can select between Use default color settings and Use Nvidia color settings? In the Nvidia Control Panel, I have obviously set 'maximum pre-rendered frames' to 1 globally, as well as globally disabled V-Sync completely & set texture filtering to high performance. Personally, I specifically play CSGO & mostly care about input lag and 'stuttering'. but seems a lot of debate about overall best optimizations. I was wondering about the above in general, and I have read the stickies.
