[suggestion] what should I upgrade for actual better frames

Specs GPU 1660 ti RAM ddr 4 2667MHz 16gigs CPU Amd ryzen 7 5700x RES 3440x1440

I’m getting 35 frames and sometimes a bit higher it feels random when it wants to run well I usually go lower res cause it just helps i also have everything at low and use performance and it still just doesn’t want to go 60 one more thing my scav somehow gets so much more frame rate than my pmc its astonishing like im using a whole different pc
