NPC animation is crap

Whenever I spawn an NPC its animation frame rate is slow. It feels like I’m playing an old DOS game not Half-Life 2.

Is there a way to fix this?

Let me rephrase the problem. When I spawn an NPC the movement is choppy, not smooth like it should be. I don’t have this problem in HL2 or any of its episodes so I don’t know how to explain it.

Try Re-installing Gmod?
I know this is like the worst choice ever.
Maybe validating files and deleting files might help.

I reinstalled the game and that fixed it. But as soon as I added any mods the problem came back.

I reported it in the beta but no-one saw it

I hope someone sees this because I would really like it to be fixed.

What addons are you using?

Make an autoexec.cfg in your cfg folder, worked for me.
