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.
