Doom 3 Tweak Guide
[Page 2] Essential Optimization
Before getting into any Doom 3 specific settings and tweaks, this section covers the obligatory system optimization information I include in all my guides. If you've followed this advice recently from one of my other guides, you can skip this section.
I strongly urge you to take some time and follow the advice below if you truly want Doom 3, and indeed every other game you own, to run at its fastest and most trouble-free.
The place to start is my System Optimization Guide for Gamers. This guide provides detailed information on where to find the latest BIOS and drivers for your system, how to install them "cleanly", understanding more about the hardware components that you're running, what overclocking is, how to correctly test an overclocked system for stability and so forth. Everything is explained from scratch, and technical jargon is kept to a minimum.
Once you've updated all your drivers and tweaked your BIOS, the next step is to examine my walkthrough guide to optimizing Windows: WinXP Tweaking: From Reformat to Relax. It has every known WindowsXP performance tweak in an easy to follow walkthrough style. It is vital to smooth, fast, stable gaming performance.
If you have time, make sure you check my second XP Guide, WinXP Tweaking: From Relax to Righteous, because it contains a wealth of information to complement the first one. Everything from troubleshooting common Windows error codes to cosmetic and convenience tweaks.
If you are wondering what Antialiasing and Anisotropic are, and how they affect a game's visual quality and performance, check out my Simple Antialiasing and Anisotropic Guide for all the details in an easy to understand format.
Finally, if you run an ATI graphics card, I have written a comprehensive ATI Catalyst Tweak Guide which covers absolutely everything about the ATI Catalysts, and all associated graphics issues. It's a must-read for ATI graphics card owners, and even Nvidia owners will get a great deal of benefit from reading the general sections of the guide.
Note that all of the above System and WinXP guides are written by me, but are on Tweaktown.com (where I used to write), so if you click the links you will be taken to that site. The ATI guide is more recent, and is right here on TweakGuides.com. If you have any issues or questions about using any of these guides, Email Me
The above information really will serve you well in the long run, not just in Doom 3. If you don't optimize your system and keep everything updated and maintained correctly you will keep running into "mysterious" problems time and time again. Do yourself a favor and when you get a chance print out these guides and spend an afternoon or two optimizing your machine the right way.
The next section goes into more detail about specific troubleshooting tips which address common Doom 3 issues.
