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.
