NVIDIA Game filter (active only on fullscreen) : Smoothness is deteriorating ONI ingame rendering.

[MorphineDZ]

If you got the feeling your ingame picture is wrong at fullscreen (bad text rendering) for no reason... it could be this.

I never used it but it was on 100% (and off) on my Nvidia game filter settings. At 0% it's fine again like before. Some Nvidia drivers update should have done something, I had this issue for some time without taking time to solve it. I tried so much things before finding this.

On borderless screen, the filter is not active and the game is fine again.

Same thing if the game window is active or not. It's easy to check then, windows key.
