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.

NVIDIA GPUs have long excelled in Doom 3, and so it is here. The Radeon X800, even with its theoretical fill rate advantage, only manages to catch the GeForce 6600 GT at 1600x1200 with 4X antialiasing. Still, the Radeon X800 hits reasonably playable frame rates at almost every resolution.
