Rainbow six setup issues

well to start with i am playing on a ps5 using PS remote control on my pc to my console it feels ok there is no delay on that part but when we get in game its jittery and not smooth at all and i am not sayign pc level smooth that will never be achieved but not choppy. I have a death adder v2 i have it set at 16k dpi but no matter what i fiddle with like deadzone or my sense nothing seems to work.
