That's the feeling I had when I first thought about writing a Doom 3 Tweak Guide. One of the most highly-anticipated games of the last few years, and the pressure was on for me to write this sucker and put it up for everyone to improve their Doom 3 performance. But enough about me.
Elegantly scary. That's the best way to describe Doom 3. It's a blend of science fiction and horror which, with the aid of an incredible graphics engine, immerses you in the heart-pounding action which underlies every aspect of this game. Now I'm actually not a huge horror fan, however for some reason the game seems to work for me. I can't put my finger on it, but I guess the main reason is the amazing game engine. This elegant, optimized, beautiful piece of work shows remarkable atmosphere and attention to detail. It is quite clear why the game took so long to develop and release - the developers were putting every ounce of their energy into making sure this thing is as close to an interactive movie as you can get on a modern PC. If you haven't played Doom 3 yet I honestly think you should try it because chances are you will like it. You can download the demo from here.
Now this isn't a review of Doom 3, as many writers better than I have already churned out dozens of those for you to read over. This is a Doom 3 Tweak Guide, and once again other writers have already turned their hand to this topic too. However I have a feeling you'll consider this the mother of all Doom 3 Tweak Guides. Why? Because this one gathers all the known tweaks, and many new ones I've experimented with and documented, all in one place. I can confidently say that if you read this guide, you will find at the very least several major tweaks which you haven't tried before, which can help you improve your performance in Doom 3. The guide covers all the in-game settings in detail, but it also goes into lengthy coverage of many of the all-important advanced console and config commands which will let you eke out as much performance as possible from an already-optimized engine.
Don't be scared - start the tweaking journey with the Doom 3 Tweak Guide!
Note: This guide refers to the latest version of Doom 3 Version 1.3.1, including the Doom 3: Resurrection of Evil expansion pack. Make sure to check back regularly for updates.
