• gm_addon_optimization_tricks Tips & Tricks to make your addon slim and fast

• gmod_random_patches A kit of in-game fixes not affecting gameplay but making the game more productive and fixing some bugs.

  ^{Most of the patches are already in the repository, but I thought it would be worth adding this as well.}

• cl_limit_render.lua

  • Disables the HDR player hardware. (High Dynamic Range)
  • Disables Pixel Shaders 2.0/1.4 and Vertex Shaders 2.0
  • Sets the maximum available DirectX version.

• Hook-Library This is a simple, realible, fast and optimized hook library for Garry's Mod. It's well tested and will not mess anything when added to your server. It can/should improve your server performance.

• BadCoderz "Find unoptimized gmod addons and KILL the devs who made them"

• Simple-Render-Distance Addon that allows you to change render distance of certain categories of entities on your server

• gmod-lua-performance A simple comparison of performance optimizations for gLUA

  • These are a few benchmarks that are tested on a Garry's Mod Server idling with DarkRP with only 1 player online. Some of those benchmarks, if possible, were also tested in a LUA5.3 console on Debian 10. If not otherwise stated differently all tests have been done on a gmod server on linux.

• gmsv_async_stdout This is a Garry's Mod server module that moves -condebug file I/O out of the main thread, which should significantly improve performance for noisy servers.

• gm_microoptimisation_war_crime This attractively named repository contains a Garry's Mod module that performs a micro optimisation that makes use of LuaJIT's constant folding on all Lua scripts.

  • The module intercepts the loading of Lua scripts and preprocesses the Lua code to replace all instances of SERVER and CLIENT with true and false depending on the current realm.

• sh_disable_widgets.lua Disables unnecessary widget hooks that no one ever uses.

• sh_limit_phys.lua Changes the physics of objects, both for the server and for the client.

• sh_nw_to_nw2.lua "I don't think this is a good idea for now, NWVars2 have some problems right now which need fixing before this can be even considered."

• sh_remove_ents.lua Deletes entities that are not normally used. I think it's worth checking if you're using any of the list.

• sh_remove_hooks.lua Deletes hooks that. Also check if you need to.

• cl_remove_ragdolls.lua

  • Starts a timer to delete all ragdolls and objects on the client side.
  • Disables the unnecessary depth display hook after death.

• sh_umsg_to_net.lua Forces the obsolete umsg library to use the new net.

• sv_animation.lua Disables server-side movement of the mouth and ears.

• sv_run_commands.lua Runs a bunch of commands to optimize the client and its graphics. Some idiot wrote this, but it seems to work.

• sv_seatsoptimaize.lua Makes corrections to the seat network?

• cl_fontcache.lua Caches fonts and prevents them from being overwritten without changes.

• cl_blink_gc.lua "This addon will check your client's current LUA memory and if too much memory is being used, will manually call for a collection of unused memory." BlinkGC

  • Reduces the amount of crashes you have due to bloated addons.
  • Gives information in your console about your Active LUA Memory.

• simplegc/sh_simplegc.lua Regularly adjusts garbage collector behavior to reduce performance overhead. scuroinside/snippets

Here are just some observations that might help you.

• In ./srcds_run - find the lines ulimit -c 2000 and replace it with ulimit -c unlimited. This will allow us to use more resources and remove some segmentation errors.

• You can play with the values in server.cfg:

    mem_max_heapsize "2048"
    threadpool_affinity "4" // 8 for octa-core, 6 for hexa-core, 4 for quad-core, 2 for double-core

• Startup parameters:

  -high High process priority

  -novid Disables video decoding function - disables codec, not splash screen, does not affect video work directly in the game, - the effect on fps is negligible

  -malloc=system Allows you to choose the size of memory blocks = loads the RAM, offloads the CPU

  -swapcores allows you to change threads for materials

  -softparticlesdefaultoff Disables particle depth filter - gives fps boost, reduces quality of particles

  -gl or -r_emulate_gl Simulates OpenGL on Windows - high fps boost, does not work for everyone
