Issues with Games on Windowed/Borderless Only having Low Contrast and Unsmooth FPS

[Denis_Twin]

Hi, I recently upgraded my PC with a fast nvme drive and cleaned it then put it properly together, then I installed windows 11 with a single drive and all, nowI noticed in games the monitor is sort of losing FPS/Stutters more like (the effect of unsynced fps I would describe as) while at the same time the brightness and contrast are not in harmony, this fixes when I put the game in full screen. This effect does not happen with windows, they move smoothly, I tested on League of Legends and Warframe amongst other titles.

The order of clean installation was as follows: W11->Chipset->GPU Drivers->Audio Drivers->Network Drivers->->W11 Update->Games, restart in between each step.

Specs can be seen in my profile, GTX980 is the unit.

Thanks in advance.

Personally I've always found some games behave strangely in windowed mode vs exclusive fullscreen, but I assume these are game that did not exhibit this before?
