Weird stretched out graphics

Alright this is really getting on my nerves. CSS was doing this awhile ago and i forgot about it. So I went ahead and bought gary’s mod yesterday and Buildings are not looking right and all the guns are stretched out really bad.

Here’s a screen

I would really appreciate some help as this game looks freaking awesome

EDIT: FIXED!!! for anyone else having this issue I used -dxlevel 81 in the launch options

What are your specs?
Use Speccy and copy the stuff.

You need a new GPU. Or -dxlevel 81 as you said.
