Try flipping those settings to high, and if you're using DLSS try balanced or quality.

I wouldn't expect you to be cpu bound at 144fps. Make sure the game is capped at that and it isn't trying to make frames over that. But then again the 12100 is only 4 cores.

Also, try closing out any other background programs you don't need. Take a look at the system processes (control shift esc) and see if anything is taxing the cpu aside from the game.

Anything is possible when it comes to MW2 and shitty optimization.
