ATI's Radeon X1900 Heats Up With 48 Shader Units

Doom 3

The next major title to hit the scene was Doom 3, a game that brought existing cards to their knees 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 (Full Screen Antialiasing) 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.

Newer uses for the Doom 3 engine include Quake 4, which produces similar results to using Doom 3 itself.
