Hello guys. I have 20 fps in gmod and i can't play in DRP and other minigames normaly

Hello it depends on your config that you have in your pc

Whats your max_fps set to?
if its capped it might be limiting your game and also check your video settings in options they might be too high

Only thing you can probably do, is upgrade your PC. :/

Either lower the settings or buy a new toasteEither lower the settings or buy a new toaster .. more powerful than oldr

Not to sound rude but gmod is gonna be gmod on high end pc's it runs like shit soemtimes, just invest in a better pc thats what i would say

set the graphic settings to lower or clean up your pc

There are configs for source engine games that help the games fps run smoothly and efficiently for low end computers. You can also make gmod a "priority application" which will end up having more of your computers power go towards it.

But let's be real if you can't run gmod with 60fps in 2018 then you need to get a new pc

Buddy, what are your PC specifications? If you answer, I will help you.

You should set the graphich setting low. It is the best way ever :D
