Debug Menu

The Debug Menu are present (in all games since Source 2007) except in Counter-Strike: Global Offensive. It can be shown by pressing Shift + F1 or by typing "debugsystemui" in the Console.

Warning:Enabling certain options like MatSys > Software Lighting can cause the game to crash.

Bug:Does not draw over video backgrounds like Portal 2's main menu.  [todo tested in?]

Note:Some games may not include the scripts/debugoptions.txt which cause the Debug Menu UI to be broken, copy it from any other Source game (example: Half-Life 2) and paste it into the same directory on a game that have the broken Debug UI.

Contains a few debugging options that run commands in the console.

The file is located here: scripts/debugoptions.txt and can be modified.
