Microstuttering with Mouse on PS5

Hi, 

i‘m playing not the first time with mouse and keyboard on PS5 in a FPS-Game, so here is the thing:

FPS are perfectly fluid, but if I want to aim precisely, the dot jumps across multiple pixels and I can’t do anything about it.

I tried to go down to 125Hz it didn’t help.

Like I said, if I play a another FPS the Mouse is as smooth as it can get, so please fix this problem.

Has someone found a work-around, or facing the same trouble?

PS: Please turn up the level of destruction ;)
