Improve your performance using modern variables with good looks, this guide aims to optimize inefficiencies while preserving as much eye candy as you can get.
 
 

Intro

This guide will greatly improve performance on modern hardware and avoid the crap and misinformation or lack of information within a lot of guides, I’ve noticed that source communities outside of TF2 seem to be, quite frankly, incompetent with cvars and how the source engine works. This guide is aimed at creating a balanced config for a modern PC, if you are on a potato you may convert the config I post (based off of but not the same as mastercomfig). https://docs.mastercomfig.com/latest/ – [mastercomfig.com] 
 
 
This Guide assumes you are well accustomed to using a PC. If you are not please look up some basic tutorials on things like Central Processing Units, Graphics Cards, Memory, or you can just copy and paste the commands into your console/autoexec and call it a day.

 
 
 

Launch Options

-novid -nojoy -nosteamcontroller -particles 1 -precachefontchars -dxlevel 95
 
 
Put this into your launch options inside of your game properties tab in steam.
 
 
-novid, removes the dumb source video, saving loading speed slightly.
 
 
-nojoy, disables joystick controls, who uses joysticks.
 
 
-nosteamcontroller self explanitory
 
 
-particles 1 Keeps particles to a minimum
 
 
-precachefontchars self explanitory (if you don’t know what precaching is look it up)
 
 
-dxlevel 95 DirectX 9 with support for extra features, using dx8 on modern hardware is horrible in gmod and does absoutely nothing but hurt performance, use dx95.
 
 
Optional
 
 
-sw -h y -w x Windowed mode, can hurt performance, x is pixel width, y is pixel height
 
-no_texture_stream, if you are not stressed for memory, disabling texture streaming can improve performance

 
 
 

Autoexec PT.1

Copy and paste this entire thing into your autoexec.cfg, if you do not have one go to /GarrysMod/garrysmod/cfg and create a file called autoexec.cfg.

64 Bit Computing

32 bit is ancient and slow, GMOD thankfully supports 64 bit which comes with a HUGE performance and feature boost and allows for GMOD to handle more memory and crash less frequently.
 
 
Go to your properties tab by right clicking on your game in steam, press betas and choose x86-64 chromium.

 
 
 

Singleplayer

While running GMOD on singleplayer in sandbox, while you are not using an addon I highly advise disabling it, if you no longer plan on using an addon EVER again uninstalling it is recommended.
 
 
 

Things to be mindful of.

Gsync reduces max framerate on GMOD cause source engine is funny like that, if you want your maximums to increase but your stability to potentially decrease I recommend disabling it.
 
 
A lot of misinformation is spread about on the internet and it saddens me that so many believe it (like putting high priority on your games in windows, please never do this.)
 
 
Software that says it will improve your performance is likely to degrade your performance and siphon data from your PC, do not install fishy software.
 
 
Trusted software that actually can improve your performance
 
 
NVCleanInstall (Nvidia Drivers)
 
SDI (General Drivers)
 
Ryzen Master/Intel XTU
 
MSI Afterburner
 
DDU (Display Driver Uninstaller, fixes errors if you encounter any on your nvidia/amd drivers.)
 
WinAero (Can disable many telementary features of windows and enables a lot of cool stuff.)
 
TCP Optimizer (Improves web data transfer)
 
Chris Titus Tech’s Debloat script
 
 
Bloatware
 
 
Razer Cortex
 
Anything from ioBit
 
CCleaner
 
Defraggler
 
Anti Virus’ (Windows defender is MORE than enough)
 
Geforce Experience
 
Most microsoft apps
 
 
Not everything I put in this guide may be accurate in a few years time or maybe even now but I tried my hardest to find reliable resources I trust.

 
 
 

More resources

A lot of extra info I shouldn’t need to cover because you can find it right here.
 
 
General
 
Mastercomfig Docs – [mastercomfig.com]  If you are confused about something with source, this will answer most of your questions and has further performance tips I did not go over here.
 
Valve Wiki – [valvesoftware.com]  Useful if you are interested in other things related to source or GMOD
 
GMOD Wiki – [facepunch.com]  Same as above
 
 
Windows
 
 

 
Chris Titus Tech does a wonderful job cleaning up windows TOOLLESS, saved my CPU and memory a lot of resources.
 
 

 
More titus stuff, extremely handy.
 
 

 
Guide on updating nvidia graphics drivers the proper way.
 
 

 
Installation for your other drivers, windows update drivers tend to be months or even sometimes years behind the latest and greatest drivers for your system.
 
 

 
Jayztwocents’ updated MSI Afterburner guide for overclocking your GPU (not very useful for source games but still helps slightly.) WARNING: THIS WILL VOID YOUR WARRANTY ON YOUR GPU
 
 

 
Nvidia Control Panel guide, nearly equivalant to AMD’s
 
 

 
Overclocking your CPU guide by jayztwocents, process is extremely similar for intel CPUs (less recommended however because intel CPU’s these days struggle to get anything out of being overclocked.) WARNING: THIS WILL VOID YOUR WARRANTY ON YOUR CPU
 
 
Windows has a lot of bloat and it takes a lot to deal with all of it, if you think you’re smart enough and you really only play source games (however other games are being well supported too on linux) I would highly suggest making the swap for the benefit of you both for performance and privacy reasons.
 
 
Linux
 
 

 
Everything you could ask for (skip the wine stuff, gmod has native linux support, set it up if you haven’t already however. It is likely if you are not running ubuntu you already know about 95% of this. I would advise against installing a custon kernel if you are running on a laptop.
 
 
As you can see linux requires much less setup than windows does for an optimal setup.

 
 
 

Conclusion

I hope I solved your performance issues running on modern hardware with GMOD, it saddens me there are no good guides out there for people these days to get a solid framerate in Garry’s Mod.
