Choppy gameplay

Hi, I’ve been having a problem with all the source games, but I just want it gone with GMod. And I’ve already asked several forums for help but none have been successfull so far.

So my problem is that my gameplay is very choppy and too fast paced. The FPS goes from 10 to 100 to 200 in a second.

I’ve tried everything, dirvers, reinstalling, verifying game cache, disabling multi core processing, enabling Vsync. I wonder if people here have any solutions to offer. I really need it working before tuesday or else I’m f*cked.

So thanks in advance for your time and whoever finds the solution will get my 10000 internet points.

Here’s a video of the issue.
