By default, when the game engine starts, it automatically detects the presence of, and runs the command variables from two specific files: DoomConfig.cfg and AutoExec.cfg. This is because the game engine resets these variables to their default state as the engine initializes at startup. remain enabled even after quitting and restarting Doom 3, you will need to insert it into a Config file, or in the game icon's Target line, both of which are covered below.Īlthough you can alter many variables by entering them into the console, most command variables need to be set each and every time you start Doom 3. Note that to make this setting (and many other settings) "stick", i.e. This means that you can now open and close the console by simply pressing the '~' key (the key above TAB), and not three keys at once. To make regular access to the console easier, enter the following line into the console: A list of commands you can enter are covered in the next section. You will see the console come down, and you can enter text at the command prompt. To open the console, start Doom 3 and then press the CTRL, ALT and ~ keys together (in some countries you will have to press CTRL, ALT and the key directly beneath the ESC key if ~ doesn't work). Through the console you can enter commands to change engine variables during the game. The console is the closest you can get to having direct real-time access to Doom 3's engine. The methods are essentially interchangeable, meaning changing the variable using one method has the same impact as doing it another way - the only difference is which is more convenient for you. To save time in this guide, I detail all the major commands one by one in the next section, and you can then decide the method to use to implement particular ones. There are two main ways in which you can access and alter command variables in Doom 3 - through the Console and through. It yields real performance improvements and allows you to exercise your right to have the game looking and feeling precisely how you want it to. Tweaking is not something people do to appear cool, nor is it a waste of time. Furthermore, since you can alter many of the settings within the game to suit your personal preferences, so too there are many more finicky settings you can access in the console to further refine image quality and controls to suit your tastes. So tweaking command variables means you can further customize the engine to run at its best on your particular setup.

But there are so many different combinations of PC hardware and software that it is impossible for any games developer to customize the game to suit your machine perfectly. Why would we want to alter these variables - shouldn't the programmers who designed the game know best and have already set them up optimally? Well of course they do, and yes Doom 3 is heavily optimized already. Since it is based on a highly advanced engine, there are many, many variables which can be adjusted to alter the way in which Doom 3 looks, sounds and operates on your machine. You can change more than just the settings available under the in-game menus in Doom 3.
