Before installing any of the configs make sure to go to steam and open the csgo properties. Then add the following to the Launch Options
-threads 9 +exec autoexec.cfg
- threads {number of cores + 1}: allow cs2 to use all CPU cores
- exec: executes a config
Copy and paste the autoexe file to this path: C:\Program Files (x86)\Steam\steamapps\common\Counter-Strike Global Offensive\game\csgo\cfg
Copy and past the video file to this path: C:\Program Files (x86)\Steam\userdata\XXXXXXXXX\730\local\cfg
