Mouse delay in some games

[Thanthos]

I have some mouse delay in some games...
For example i tried DOOM demo... mouse delay
rainbow six siege free weekend that there was... mouse delay
on overwatch mouse delay... (if i put on low and lock fps on 120FPS no mouse delay)
i have roccat lua mouse...
what can be the issue?

Vsync will add input lag, as well as triple buffering. If both of those options are disabled, then I will next make sure you are in Fullscreen mode instead of borderless windowed.

Done it already... Anything else?

Is your keyboard delayed too, or just the mouse?

Only mouse

Have you tried completely uninstalling the mouse drivers and running the Windows default ones?

How do I do that? I will probably reinstall windows if it won't fix.
