We took a lot of
time studying the Anti-Aliasing quality of the GFFX 5900
Ultra. In fact, we re-took shots several times with
Hypersnap with its "post processing" setting enabled, to
make sure we were capturing the true quality with each
card's output. We then dropped the shots into high
quality, low compression JPEGs to make sure artifacts didn't
clutter the edge cleanliness in each scene. Here are
the results. Again, put your screen into 1024X768
resolution for the truest viewing of these shots.

First things
first, this area and scene in the UT2003 map we chose, is
especially difficult to clean up with AA. Look at the
staircases and the far wall, on the left of the screen.
Here you'll see with good detail, what each card is doing to
get rid of the jaggies in the scene. This scene is a
bear to make really crisp on all visible edges and
there are a lot of them. In our opinion, up to 2X mode
both cards are about on par with each other and 3X or
"Quincunx" mode for NVIDIA is definitely smoother but things
are blurred slightly as a result. It's at 4X mode that
things begin to fall apart a bit for the NV35. 4X
definitely looks sharper for the ATi card but in 6X mode,
both cards seem to level out again. At 8X for the
NV35, we're pretty sure the AA engine was reverting
back to 6X mode, because there was virtually no improvement.
So we set out to
look at AA through the eyes of another FPS, Delta Force
Black Hawk Down, from Novalogic.

Focus your
attention on the lamp post and the docks across the water,
in this scene. At 4X and above, we'll tip our
collective hats again to the ATi Radeon 9800 Pro.
Again, at 1024X768, NVIDIA's 8X setting doesn't seem to be
doing much more than in 6X mode. In our opinion, ATi's
6X quality is the winner here hands down but again, you be
the judge for yourself.
