Low fps in Tarkov 13.5 Share your perfomance and tips!

Just wondering, if it's okay to have such poor perfomance on my system. My friend is playing on a laptop with rtx 3060 AMD Ryzen 7 5800H 3.2MHz, 16 gb ram in 1080p and getting pretty much the same fps as me.
System:
GPU: GIGABYTE GeForce RTX 2080 GAMING OC 2950 MHz
CPU: Intel Core i7 8700K 4.5 MHz
RAM: 32Gb 3400MHz Corsair Vengeance LPX 3000 MHz.
Resolution: 2560×1440
I'm averaging around 55 fps on Interchange for example. Dropping to 40, and rarely it jumps up to 80 but not for long, but most of the time it's 50-60 fps with occasional stutters. Lowest settings, automatic ram cleaner: on, physical cores only: on, dlss and reflex off, paging file is customized, Process Lasso instaled with all the settings from the guides, ISLC is set, game mode on, high perfomance in graphics settings, full screen optimization is on, xmp on. All theese things didn't help much.
