Performance Comparisons with Doom 3 - Single Player

Doom 3
id Software's games have long been pushing the limits of 3D graphics. Quake, Quake 2, and Quake 3 were all instrumental in the success of 3D accelerators on the PC. Now, many years later, with virtually every new desktop computer shipping with some sort of 3D accelerator, id is at it again with the visually stunning Doom 3. Like most of id's previous titles, Doom 3 is an OpenGL game that uses extremely high-detailed textures and a ton of dynamic lighting and shadows. We ran this batch of Doom 3 single player benchmarks using a custom demo with the game set to its "High-Quality" mode, at resolutions of 1,280 x 1,024 and 1,600 x 1,200 without anti-aliasing enabled and then again with 4X AA and 8X aniso enabled simultaneously.


Ever since its release, Doom 3 performance has been somewhat of a feather in NVIDIA's cap. Their high-end cards simply dominate ATI's current generation with regard to Doom 3 frame rates, as is evident in the graphs above. A single GeForce 7800 GTX is faster than a pair of X850 XT cards running in CrossFire mode, not to mention the 7800 GTX SLI and GeForce 6800 Ultra SLI configurations which are faster as well.

If we focus only on CrossFire's impact on performance, however, things are not all bad. At a resolution of 1280x1024, enabling CrossFire results in performance increases of 65% (No AA) and 79% (4x / 8x). And Doom 3's performance scaled even more at the higher resolution. With Doom 3 running at 1600x1200, enabling CrossFire boosted Doom 3's performance by 76% (No AA) and 81% (4x / 8x).
