High end PC & Game is not smooth

This is the only game that is not buttery smooth on my system

I have RTX 5080 with amd ryzen 7 9800x3d
RAM 32GB DDR5 6600HZ
my monitor is Asus rog strix xg27acdng 2k 360 hz with freesync and g-sync compatiability

My game is not that smooth in so many sitiuations,I can't move my aim as the enemies move not because of mouse sensitivity or aim problems but because the game is not smooth
I've tried so many shooter games and this issue only exist in bf6 

I play on 2k with low graphics

when I try my friend's pc which has 4060Ti and much less CPU and RAM the game is perfect and I can even switch aim between 4 and 5 enemies with so much smoothness
I am not close to do that on my high end PC
