Guide Optimal FPS in Gmod Configuration(s)

[Aesop]

I have an ancient install of Gmod and with that, I run into frequent performance issues due to bloat. This gave me an immediate, noticeable increase in performance.
Shoutout to the original guide which I ripped off and stuck here. x64 branch is already a known thing, but there's some new in here that I didn't bother trying until now.

Step 1: Install the Chromium Beta branch

• Right click Gmod.
• Choose "Properties".
• Go to the "Betas" Section.
• Select the "x86-64 - Chromium + 64-bit binaries" Beta.
• Wait for it to install

Step 2: Modify the game files
Open the config file >>

• Right click gmod
• Go to the Games properties again
• Go to the "Installed Files" section
• Click "Browse"
• Navigate to this folder "./garrysmod/cfg"
• Open the "autoexec.cfg" file with notepad, or another text editor.
• Paste these variables into the file:
  

  gmod_mcore_test 1
  mat_queue_mode 2
  cl_threaded_bone_setup 1
  cl_threaded_client_leaf_system 1
  r_threaded_client_shadow_manager 1
  r_threaded_particles 1
  r_threaded_renderables 1
  r_queued_ropes 1
  studio_queue_mode 1
  mat_specular 1
  
  fps_max framerate_value
  menu_cleanupgmas
  host_writeconfig

• Change "framerate_value" to the desired Framerate. For the most optimal result set your monitors refresh rate. When in doubt, 60 is adequate.
• Save the file

Step 3: Add launch option

• Again, open the Game's Properties
• Navigate to the "General" Section
• Down in the "Launch Options" Box, paste this:
  

  +exec autoexec.cfg

Step 4a: Bonus launch options

• I personally use the following to allow my gmod to open in windowed borderless. Here's how my launch options are configured:
