What is GMDM resorces

i dont play muitiplayer whats it for its 2.09 mb and my addons folders is 2.29 GB

size on disc 2.34 GB Any way i can make my gmod faster like type fps max 300 in console?

What does 2.09mb matter? Thats practically nothing,
And there are a few ways to make gmod run faster:

  1. Go to Steam > Games > Right click Gmod > Defrag game files
  2. Remove unused addons
  3. start gmod with this:

-window -dxlevel 80

  1. Get a better PC
