modern warfare terrible stuttering

[Ls9L]

so i just bought modern warfare for pc and i have all the settings to low and im getting a constant 120 fps but the frame stutter is horrendous,when i try shooting at someone the frame stutter is so bad it looks like it skips a bunch of frames and the next frame is not even pointing at the target when 2 seconds before i was pointing right at him. i play rust,fortnite,csgo,fallout76,pcbuildsim,the forest,beamng etc etc and none of these games stutter at all they feel butter smooth so i dont think its because of my pc specs but here they are

gpu- rx570 8gb  (oc to 1450 mhz lmao) weird thing is that all games get my gpu to about 75-85c but on modern warfare its staying at 55-60c

cpu ryzen 5 3600 (oc to 4.2ghz)

How much system RAM do you have? It's pretty damn heavy on system RAM, so that could be your issue.

Never mind, you've got 16GB. Is the game on a hard drive?
