This launch option can help players with lower-end computers to get less lag and a few more fps, but it is not a guarantee. Launching in high mode will start the game in a high-priority way. If it isn’t and you set this launch option to 120, you can seriously damage your monitor. Setting up refresh rate will make sense if your monitor’s maximum refresh rate is higher than 60. You can force your monitor to run at a specific refresh rate with this launch option. If this launch option is set, the offline servers will always run at tick rate 128.
If you create an offline game with bots without this launch options set, the designed server will run at tick rate 64. A must-have launch option, in my opinion, because I find that intro is annoying as hell. Starting the game with this launch option will remove the valve intro that plays typically at the beginning. Some people still like to set this launch option to see echos they put in their auto exec and know that CSGO executed the auto exec correctly. There is no real need to set this launch option in cs: go because you can just put a toggle key in your in-game options or your auto exec, and, unlike cs:s, the toggle key works. Setting this launch option will open the console automatically when opening the game.
