Unreal Tournament 2003
Here we have the latest and greatest multiplayer first-person shooter engine. UT2003 uses larger textures and more polygons than older games, and it uses pixel shaders for some effects.

Without aniso and AA, the FX battles the ATI cards for supremacy. The FX does relatively better with UT's high detail settings than with lower detail.

With AA and aniso, the pattern reverses itself. The FX is competitive at the low-detail settings, but has trouble keeping up at the higher detail level.
