Anti-Aliasing Benchmarks
With modern graphics, increasing the resolution of game play is no longer the
way to improve what eyes see. Anisotropic Filtering, Anti-Aliasing and other
such techniques are being used to enhance the image on the screen.
Anti Aliasing is a method of reducing the viewable "jaggies". This
process smoothes the stepped edges by blending so they appear smooth. The pictures
below show a very small part of a single frame from the "Battle of Proxycon"
game test. The edge shown is the peak of a soldiers helmet, enlarged 300%.

As you can see, the image looks systematically better as you up the sampling
rate. When put back to their original picture sizes, you can imagine general
image quality is greatly increased.
Obviously, this has a performance impact, so here are the average frames per
second for the 3dmark 2003 game tests, run with no antialiasing, then 2x, 4x
and 6x levels of Anti-Aliasing.
The difference figure is created from the average FPS of all the game tests
and shows the performance difference between each type of Anti-Aliasing, compared
with no Anti-Aliasing. All tests were still done at 1024x768.
The tests are:
- Game Test 1: Wings of Fury
- Game Test 2: Battle of Proxycon
- Game Test 3: Trolls Lair
- Game Test 4: Mother Nature
