Steam Set Launch Options and Full List

Steam has the option available to set launch options which allow tweaking when Steam launches. This can be used to fix many solutions and also provide convenience to those who wish to open their client in a different way. We have listed down a number of different launch options along with their description. First, we will show you how to launch Steam using the launch options using the file “steam.exe”.

Please note that this guide is meant for advanced Steam users who know their way around commands. Newbies are advised to stay away from altering things they don’t know about.

How to set launch options:

We have added the ‘-offline’ launch option to help you understand the mechanics involved. You can replace ‘-offline’ with any other launch option you wish.

  1. Locate your Steam client. The default location is C:/Program Files (x86)/Steam.
  2. Create a shortcut of Steam in the same directory.
  3. Click ‘Properties’ and head over to the ‘General’ tab.
  4. In the ‘Target’ dialogue box, add ‘offline’ in the end. The final result looks like this “C:\Program Files (x86)\Steam\Steam.exe”-offline

  1. Open task manager and end all Steam processes like explained above.
  2. Re-launch Steam using the shortcut and click Go Offline by clicking Steam located on the top left side of the client.

There is also a way you can set launch options for any game.

  1. Select the Library tab present at top of the Steam client. Here all your installed games are listed.
  2. Right click on the game and select Properties from the list of options available.
  3. Navigate to the General tab and here will see a Set Launch Options button. Click it.
  4. A small new window will come forward with a dialogue box present. Enter the launch option you wish to apply and save changes. Now whenever you launch the game, it will launch keeping these options in mind.
