Is it normal to not be able to jump worth shit?

Seriously, I can’t even jump on a simple wooden crate. Is this normal or did I fuck my game up somehow?
Edit: I can do it using crouch jumping, but I can remember being able to jump much, much higher.

Aye, check your addons for movement related things, like the climb swep.

You have managed to get your tickrate to 100

use noclip :v:
