Is there a way to improve FPS?

I’ve tried some of the various graphic options, and while that slightly improves my FPS everything is still a bit jittery, and sometimes things (people, animals, zombies) don’t appear until I’m right next to them.

um

grass.on false
render.level 0

are the most important changes
and dont worry about render.level 0 you wont get any disadvantage on players, i tested the distance and it stays the same, it just renders objects like bases that are near

dont install ANY game/pc boosters /facepalm
