Blocky Movement (Need Help)

Alright, since the last update (New noclip?), player movement in Gmod (Singleplayer) has been blocky as hell. I didn’t find solution via googling, but I noticed that some people have this problem too.

I’ve tried different things (Changing Graphics, Deleting Addons, Reinstalling Gmod couple of times etc.), but it didn’t help at all.

So is there a way to fix this problem (Console command or something like that?). It’s so annoying.

what do you mean by blocky movement?
