Autoexec

Autoexec.cfg

Overview

The autoexec is a configuration file that stores settings. .cfg Files can be executed by Portal 2, and the autoexec is a configuration file that is executed upon launch of your game. It is most commonly used to alter settings that are reverted after every game close.

For more information on .cfg files, and configuration files check out the page on .cfg Files and Aliases

Where is my autoexec?

The autoexec is located at Portal 2's installation folder (usually C:\Program Files (x86)\Steam\steamapps\common\Portal 2\portal2\cfg), and is called autoexec.cfg. There is a chance you don't have this file by default, creating it should be fine, just ensure that you have the right file type. How to show/change file names on Windows 10.

What should be in my autoexec?

You can put anything you want in your autoexec, a good autoexec should save you time and keep you from having to type any commands into Portal 2 when you launch the game.

• SAR commands are not kept between sessions, as well as SAR loading itself.
• Aliases are not kept between sessions.
• cvars like cl_showpos and r_portal_use_pvs_optimization are reverted to 0 after restarting.

Alias

Alias is a console command that takes two arguments. The first argument will be the name of whatever command you are creating, and the second argument is what will happen as the result of you calling that command. They are incredibly powerful, but are forgotten by the game upon closing, so they are perfect for an autoexec.

Showing Textures Out-of-bounds

By default, after leaving the games normal bounds, the surrounding area is just white. You can fix this to see out of bounds with the command r_portal_use_pvs_optimization 0. It's another command that should be placed in your autoexec if you plan on ever playing around OoB.
