After the new update, it became possible to increase your FPS due to improved multi-core render or something. It works in a test mode, and to turn it on, enter the following command in the console!
Here is the command Gmod_mcore_test 1; mat_queue_mode -1; cl_threaded_bone_setup 1
To perform the method, turn the console on the main menu (Shift + ~) If it does not turn on, turn it on first in the game settings. Insert that command, and press Enter.
Now, when you play on servers or in a singleplayer, your FPS became really better , and you can play comfortably (or super comfortable)! You need to run this command every launch of Gmod. Rate this guide and share it with the friends!
You can add it to the autoexec.cfg , if u don't want to enter this command every single launch PATH: Steam\steamapps\common\GarrysMod\garrysmod\cfg Add it to the autoexec.cfg and save this file then.
