If your first instance of the game is only on the title screen the second will be significantly faster to start Running a new game while one is already in a game/not the title screen, it can take some time to initialize and will freeze the currently running game for some time.Keep in mind connecting to an online multiplayer game with the same game will disconnect you.The command should work on Mac and Linux systems, but the process will be a bit different.This will bypass the “Only one instance of the game can be running” dialogue.if you don’t see the hl2 folder or there’s only one sourcemod folder, this is not needed (like in Gmod’s case, it does not include any other sourcemod folder) In most cases, you will also need to specify “-game ” as most games include their own folder and hl2, or multiple games share one folder (HL2, Episodes, and HL1 Source), and an error will occur.In cmd type your games executable (most of the time, ‘hl2’) and type -multirun after a space, in PowerShell, type.

Make sure a source game is already running beforehand (otherwise this command doesn’t do anything different!).
