Doom 3 Benchmarking

Again, Doom 3 runs in AFR mode with our dual GeForce 6800 cards, in SLI on the ASUS A8N-SLI nForce4 motherboard.  NVIDIA's edge in Doom 3 has always been significant versus ATi solutions.  Let's see what SLI does to widen that gap.

Benchmarks & Comparisons With Doom 3
AFR For SLI Performance

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, years later, with virtually every new desktop computer shipping with a 3D accelerator, id is at it again with the release of the visually stunning Doom 3.  Doom 3 is an OpenGL game using extremely high-detailed textures and a ton of dynamic lighting and shadows.  We ran this benchmark using custom demos with Doom 3 set to its "High-Quality" mode, at resolutions of 1,024 x 768 and 1,600 x 1,200 without any AA and then with 4X antialiasing and 8X anisotropic filtering enabled.  Note: Doom 3 enabled 8X anisotropic filtering automatically when set to "High Quality" in the game's control panel.



We don't even have to do the math for you here.  The numbers don't lie, and this is one scenario where the marketing boys were actually speaking mostly the truth!  With AA and AF enabled, you're looking at a 2X SLI performance lead over ATi's fastest card and nearly that (80% or so) as compared to single GeForce 6800 series performance.  If you're a "Doom 3er", this is nirvana but for a price.  Because there will most likely be more than a few titles based on the Doom 3 engine coming to market in the next few years, this performance profile for NVIDIA's SLI solutions is only that much more significant, as well. 

Can you believe 1,600 x 1,200, with all the eye candy turned on, with AA and AF, at 75 - 83 frames per second?? Believe it...
