"To gain a better understanding of DOOM 3's image quality modes, you'll want to read id programmer Robert Duffy's July 26 .plan update. Duffy explains the differences between the Medium and High Quality modes we used for testing and why things look the way they do. Perhaps the most important thing to take away from that .plan update is that DOOM 3's High Quality mode uses 8X anisotropic filtering.

One more thing: although I've managed to include 17 different graphics cards in this comparison, this is by no means a complete collection of low-end, mid-range, and former high-end graphics cards. I'm limited by the stock in the Benchmarking Sweatshop, so if you don't see a specific card tested, it's because I don't have one on hand. I do have a couple of DeltaChrome cards in-house, but S3's current drivers don't work with DOOM 3, so I couldn't include the S8 and S4 Pro in the comparison, either."
