driver optimizations, that have been targeted at Anisotropic
Filtering performance and run a psuedo-filtering mode,
rather than true Aniso Filtering, will skew the numbers in
our Unreal Tournament tests. However, image quality is
still fairly good with the GeForce FX 5900 Ultra here, with
the exception of NVIDIA's AA quality and since this game and
its game engine are so popular, we decided to roll with the
numbers regardless. However, we'll reserve too much
commentary and let the scores do the talking, since the
picture is fairly obvious to those of you in the know.
With Unreal Tournament 2003
Performance In The Mainstream
attention to the numbers here just a bit to put things in
perspective. The Radeon 9800 XT is able to best the
GeForce FX 5900 Ultra with 4X AA enabled but when we enable
8X AF, the GFFX takes the lead handily. Again, this
doesn't correlate to what we've seen in the past here and as
a few other sites around the net have noted recently,
NVIDIA's image quality doesn't exactly stack up versus ATi's
in Aniso Filtering with UT2003. The real story here is
that the new Radeon 9800 XT drops in a solid 23 - 25%
performance improvement with AA and AF enabled, versus a
Radron 9800 Pro 128MB card and about a 9 - 10% improvement
over the 256MB Radeon 9800, in this test.
Stealth Pixel Shading Redefined
currently has a bug in the game engine that doesn't allow
either NVIDIA or ATi cards to properly run AA modes.
As such, we've taken scores with various levels of
Anisotropic Filtering enabled or at default in the driver
Game, set and
match...The Radeons all sweep this test, with the Radeon
9800 XT posting a 7 - 10% lead over the Radeon 9800 Pro
cards. NVIDIA's product doesn't like the DX8 Water
Pixel Shader effect, that is used in the Caspian Oil Rig
demo, that was created by the folks at Beyond 3D.
Although, this effect isn't utilized in every level or map
in the game, the effect itself is indicative of the types of
high quality viisuals you'll begin to see more and more of,
in upcoming DX8 and DX9 titles.
