Unreal Tournament 2003
In standard quality, no differences are evident between 256 MB and 128 MB of memory, and none appear between AGP 4x and 8x, either. With 4x FSAA, the 256 MB version has minimal advantages, but this can be assigned to the slightly raised memory clock. It's only with 6x FSAA that the 128 MB Radeon 9800 PRO starts to swap. The difference between AGP 4x and 8x consists of only five frames per second. The advantage of the 256 MB card compared to the 128 MB version is only a meager seven fps at 6xFSAA with an AGP 8x motherboard. As expected, with the 256 MB card there's no difference between AGP 4x and AGP 8x.
