Use this guide. I did and can get 120 easily in COD:Modern Warfare 2019
Normally, we'd suggest a slew of settings to tweak so you can eke out some additional performance, but in the case of Modern Warfare everything's been streamlined to ensure that the default settings run well on the widest array of systems possible. That leaves us with only Screen Space Reflections to switch to Normal, and Depth of Field to Off in multiplayer.
Instead, the biggest gains will be found scaling your resolution. For instance, 80-90% at 3840x2160 boosts performance by double digits, with only a minimal reduction in clarity (which you could counteract by using GeForce Experience's Alt+F3 Sharpening filter).
Enthusiasts will perhaps be disappointed by the lack of Ultra future-proofed settings, but you can't argue the game looks great, runs fast, and will deliver a great visual experience to tons of PC gamers.
thank you ill take a look at that
The biggest MW COD fps killer appears to be under Graphic / Render Resolution. Since you are running a 1440 display make sure this setting is set to 1440 as well (last number). Adjusting to a higher rendering above your 1440 display will not only reduce fps considerably but also distort the game graphics.
Also you need to OC your card as well as far as it will OC. MW seems somewhat demanding on the video card.
Adjusting the Rendering Resolution from 4K to 2K improved my fps from 50's tp 90's with my monitor refresh rate at 144, 1440 (2k) and Render Resolution at 1440 as well. Blur off and all other setting set to max.
I just cant understand why the darn movie at start up keeps playing when I have that option disabled.
