Doom 3 - Delta Labs
We'll kick off our gaming benchmarks with Doom 3. Our first Doom 3 test uses a gameplay demo we recorded inside the Delta Labs complex, and it represents the sorts of graphics loads you'll find in most of the game's single-player levels. We've tested with Doom 3's High Quality mode, which turns on 8X anisotropic filtering by default.

The GeForce 6600 GT AGP's performance in our DOOM 3 Delta Labs demo is fantastic. The card averages over 60 frames per second at 1600x1200 and is nearly as fast as the more expensive GeForce 6800. The 6600 GT AGP loses some of its luster when we turn on 4X antialiasing, though. With 4X AA, the card is considerably slower than the GeForce 6800, but still much faster than the Radeon 9800 Pro.
