Performance issues with good setup

i have performance issues too…fps are very low, i can drop to 14, barely reach 50. that makes the game unplayable. it can happen in most areas and i thought that changing my graphic options set the issue but no.
here is my setup :
ROG strix B550 F wifi2
32 GB Ram
3080 TI on display port
AMD ryzen 7 5800X
screen samsung odyssey G5 144hz
