Other information

Source Dedicated Server

Works with multiple Source-based games.

See the "Source Dedicated Server", "SteamCMD" (for most Source games), or "HLDUSUpdateTool" (for games which haven't received updates for a while) articles on the Valve Developer Community Wiki for more information.

See also the the Steam Support article for setting up a Source Dedicated Server through Steam and the article on setting one up stand-alone.

Command line arguments

Can be used to increase performance in Source-based games and fix various problems.

Longer launch options can be stored in an autoexec.cfg (without the - prefix and with every command on its own line) in the game's config folder for easier readability and editing. Starting the game with the -autoexec command is required.

See the Command Line Options article on the Valve Developer Community Wiki for more information.

Issues fixed

Game launches in an unsupported or unusable resolution

Add your resolution to the game's launch options[citation needed]
Navigate through your Steam library and open the game's properties. Add -width X -height Y to the game's launch options. Where X is your horizontal resolution and Y your vertical resolution. Press OK.

Console doesn't open

Make sure developer console is enabled. This can usually be toggled in the Advanced Settings under Keyboard/Controls.

You can't use the button above Tab ↹ and to the left of 1 to open the console, this is because the game only recognizes ~, which is not present on non-US keyboard layouts. There are two possible solutions:

Bind another key[citation needed]
Navigate through your Steam library and open the game's properties. Add -console to the game's launch options. Start the game. Type in the console bind x toggleconsole (where x is the button you want permanently assign to this). Notes You can then remove the -console switch.

Bind console key with autoexec[citation needed]
Navigate to the configuration file location. Create or open your autoexec.cfg file with your text file editor of choice. Make a new line and write bind x toggleconsole where x is the button you'll press to open up the console. Save and exit the text editor. Notes You might need add exec autoexec to your launch parameters if it doesn't get executed automatically by the game.

Change keyboard layout[citation needed]
Open Language and Country settings in Windows's the control panel. Select Change keyboard into Language and Keyboard tab. Add English (US) keyboard to the list of the available. Make sure you are using it and save.

Missing models or textures

Any missing textures will appear as a black and pink checkerboard pattern, missing models are represented by a large red ERROR model.

Instructions[citation needed]
Find the desired game in the Library, then Right Click on it. Select Properties, Local Files, then push the Verify Integrity of Game Cache... button.

Some maps are way too dark on Intel HD Graphics GPUs

Games and maps using ambient occlusion can be very dark on Intel HD Graphics. Upstream issue here.

Modify configuration file

If the console mat_tonemapping_occlusion_use_stencil is available (e.g. in Garry's Mod): Set mat_tonemapping_occlusion_use_stencil to 1 Notes If the setting does not save, add it to the games autoexec.cfg If the console variable is not available (e.g. in CS:GO or Left 4 Dead 2): Edit Steam\userdata\<userid>\<appid>\local\cfg\video.txt Add "setting.mat_tonemapping_occlusion_use_stencil" "1" Save and set the file to read-only. Notes Not setting the file permissions to read-only will revert the change on the next game launch.

Enabling 7.1 Output (Windows Vista and later)

Even when 7.1 speaker option is selected, game may still output to only 5 speakers, leaving the side surround speakers void of sound.

This issue is typically present in Source engine games that use Miles Sound System.

Enable 7.1 Speaker Output In Source Engine Games[citation needed]

Refer to Restoring Legacy Audio Effects (DirectSound 3D) and enable DirectSound 3D based on the audio device you have. Run the game and open the console (~). In the console, type: snd_legacy_surround 1 Restart the game. Select 7.1 speaker output from the game's options. Notes If only up to 5.1 is available, select 5.1 and the game will discretely output to 7 speakers. If using Creative's ALchemy, Source engine games typically need Buffers set to 5 and Duration set to 10.
