Right-Click the game, then click properties, - Go to Betas, - Select X86-64 - Chromium + 64-bit binaries, - Close the menu and wait for the game to update. Go to your library in Steam, find Garry's mod. RUN THE x86_64 BIT BRANCH This 'beta' branch will allow Garry's Mod to use more of your resources, which equals to better performance.Doing so will significantly increase performance (regardless if Garry's Mod is CPU bound or not.) FOR GAMING LAPTOP USERS: If you have a feature called MUX SWITCH, make sure you set from 'Hybrid Graphics' to 'Dedicated Graphics'.TURN OFF PROGRAMS DURING GAME PLAY! If you use apps that consume hardware resources, make sure you turn them off.Document what drivers are stable and don't update until the said drivers are stable enough (AMD GPU users can ignore this, as apparently latest and greatest is good for them?) Sometimes there can be either performance issues or memory leaks, which can cause major issues especially during gaming or high load workouts. MAKE SURE THE DRIVERS ARE STABLE! The latest and greatest driver version for both your cpu and gpu won't automatically mean great performance.Check both Linux Build/Proton version and see which runs best for you. The LINUX NATIVE BUILD is not great as it lacks some features from the non-native build.

Don't use DXVK-ASYNC=1 as 'ASYNC' has been replaced.

FOR LINUX USERS: Make sure the Proton/Proton-GE versions are up to date.

Just make sure you know what you are removing.)

DEBLOAT YOUR OS! If you use WINDOWS, there are plenty of tools to debloat your OS, one of which is WinUtil(it is completely safe.
