Doom 3 "Turkey Baster"

Our Doom 3 "Turkey Baster" test uses and extended sequence from the Alpha Labs 1 level and is intended to be used in Doom 3's Ultra mode as a slightly heavier stress test as this level has a few areas where texture swapping will occur on 256MB boards.

6800 Ultra -2.0% -1.4% -0.4% 9.7% 28.0%

Thanks to the performance of these boards we can see that this test is also CPU limited for the most part, with only the 6800 Ultra displaying much of a graphics limitation that enables the 7800 GTX to have a 20% performance difference at high resolutions.

6800 Ultra -0.2% 5.7% 20.8% 51.6% 66.4%

With 4x FSAA and 8x AF enabled the test does become a little less system limited, such that the 7800 GTX opens up a 34% performance advantage over the 6800 Ultra, staying above an average of 60 FPS at 1600x1200.
