Console commands[edit]

Games running on the Source engine can utilize Source Engine Console Commands for various tasks.
Enabling the console in Source games[citation needed]
  1. Launch the game
  2. From the main menu select Options
  3. Select the Keyboard tab
  4. Click the Advanced button
  5. Check the box next to Enable developer console (~)
  6. Click Apply


Press ~ to open the console.
Some commands may first require you enabling sv_cheats. You can do so with sv_cheats 1.
Many servers will not allow you to play with cheats enabled, or will disable them upon entering the server.
Users without a US keyboard could experience some problems.

Command line arguments[edit]

View this Steam Support Article regarding launch options as well as the relevant Valve Developer wiki page for further information and a list of useful Source engine launch options.
Some useful commands can be found in the table below.
Command Output
-autoconfig Restores video and performance settings to default for the current hardware detected. Ignores settings inside any .cfg files until this parameter is removed.
-console Starts the game with the developer console enabled.
-dxlevel xx Forces the game to launch in a specific DirectX version, where xx is: 80 (DirectX 8 (buggy, use 81 instead for high performance)), 81 (DirectX 8.1), 90 (DX9 with Shader Model 2), 95 (DX9 with Shader Model 3) and 98 (DX9 on DX10 hardware (SM 4)). Remove this argument after starting CS:S once or it will keep reseting your other settings. The overridden DirectX version will still be saved (mat_dxlevel).
-h # or -height # Forces the engine to start with resolution set to #.
-w # or -width # Forces the engine to start with resolution set to #.
