I have i9-10900K, 3080, 32GB RAM, M.2 SSD so a pretty decent system. With the graphics tuning fairly high and on 4K I get 25-50 FPS depending on the situation, with occasional stutters. The game is totally playable at 30+, its slightly noticeable 25-30, starts to get irritating below 20. It doesn’t feel any different whether you are at 30 or 50 to be honest. So, optimise settings to reduce load on your CPU (other traffic is a good suggestion above), and you will find you can turn some of your graphics stuff up quite a bit and it will look nicer without impacting FPS. Get to 30-40 FPS in some circumstances then turn the framerate monitoring off!
