Doom 3
The Doom 3 engine can put cards through an ordeal with its complex lighting. It was the first game in a long time that made gamers change what they thought were acceptable frame rates. Prior to the game's release, gamers expected frames rates to be in the hundreds-per-second range. Afterwards, they began settling for anything above 30 frames per second with Doom 3.
We use the Doom 3 default time demo, "demo1," for each of our tests. First, the graphics card driver is set to "application controlled." Then, for the first run, we disable FSAA and then run the high-quality setting in the game. When set at high quality, anisotropic filtering is automatically enabled and set to eight-sample mode. For the second run, we turn FSAA to 4X to really tax the GPU.
