framerate progressively worsens as players join your world

im genuinely getting sick of these patch updates that do nothing but introduce problems specifically for pc users

First there was memory leaks that i reported in a post 2 months ago that never got resolved
now theres this

I launch a world and it runs 200+fps just fine, but as players join it, the framerate becomes slowly jittery and unstable, this is ESPECIALLY noticeable on vibrant visuals, as the fps doesnt just become unstable, but it can go from being smooth 200+fps to around 70fps
