Gaming: Doom 3
Putting Doom 3 in our motherboard test suite was yet another attempt to see some difference between the AGP and PCIe motherboards, as this will soon become a bigger topic of discussion among gamers and enthusiasts. I ran the default timedemo, ‘timedemo demo 1’, three times on each resolution and quality setting, and took the average of the second and third scores. We ignored the first one as it was always much slower than the following ones as the game was caching textures off the hard drive. The tests were done in Medium Quality (MQ), High Quality (HQ) and Ultra Quality (UQ) and in both 0xAA and 4xAA modes.
In looking at the resolutions without AA enabled, we see that the processors play a key part in performance until you get above the 1024×768 resolution. The AMD FX-55 processor shows a nice jump in the lower resolutions and keeps the AMD gaming dominance in place.
With AA enabled at 4x, the processor bottleneck is removed at 1024×768, where the video card becomes the most important part of the system. If you see the last two Intel scores, you’ll notice they are significantly lower than the rest of the scores, but I can’t find any reason for this to be the case, though the results are completely repeatable.
