Doom 3 – High End
Doom3 (OpenGL)

Without a doubt, the release of Doom 3 has been one of the most anticipated gaming releases on the PC market, ever.  And it’s easy to see why; 4 years of heavy press-covered development and a promise to change the way computer games look.  John Carmack and the id Software team are never one to disappoint. 

For our testing, we set the Image Quality to High and turned on all the options that you see in the screen shots below.

For our image quality settings during testing, we set both ATI and NVIDIA drivers to “Application Controlled” Antialiasing and Anisotropic filtering, leaving the Doom 3 engine the task of setting the options.  Since we left the game on High Quality mode, 8x AF was always enabled, and we ran tests with both Antialiasing set at Off and at 4x.

Since Doom 3 has a convenient 60 FPS cap on performance, the X1800 XT actually does quite well here keeping up with the performance levels of the GTX.

The XL card running at much lower frequencies isn’t as lucky and sees a noticeable performance gap between it and the GT and GTX cards from NVIDIA.  As we expect to see with Doom 3 and OpenGL apps in general, the R520 is lacking.
