I often have a steady 20 fps with a pc that should get more than a 100 fps. (got the amd radeon rx 5700 xt and amd ryzen 5 3600x with 16GB), I even had gpu crashes when playing for a while on a friend's server. Yes my drivers are all updated. Also switching from 4k to 1080p (or even 1440P) doesn't even increase performance or lowering graphical options. It's just plainly bad performance.
