UT2003 MAX settings
We've tried to compare like for like thus far. We'll re-run UT2003's benchmarks, but this time we'll set each card to its maximum possible image quality setting. This will yield results that aren't comparable over GPUs, although this should tell us just how they perform when cranked up to their respective maximums. For the ATI cards, this is 6x FSAA and 16x AF. For the NVIDIA cards, this is 8x AA and 8x AF.
The FX5900 Ultra finds 8x FSAA truly savage, even with 27.2GB under the hood. It's remarkable to see the drop in performance from 4x FSAA to 8x FSAA. All the bandwidth-saving colour compressing tricks up the FX5900 Ultra's sleeve don't stop it from being hit for six with 8x FSAA.
