The next game engine to come onto the horizon was the Doom 3 engine, which will put cards through an ordeal with its complex lighting. 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 we disable FSAA and the high-quality setting in the game for the first run. 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.
