High Quality AA and AF
In our High Quality tests we bump the Antialiasing (AA) and Anisotropic Filtering (AF) up causing the card(s) to be put under more load.
This usually helps us remove the CPU limitation. We use 4 x AA and 8 x AF as this is quite a common setup for most people who are venturing into the AA and AF area.
3DMark 5 again shows that performance is quite close between the two cards but this time around the 7800GT does offer a more visible difference.
Half Life 2 with AA and AF on brings both cards to exactly the same point which is interesting seen the 7800GT saw larger improvements when running without AA and AF.
Doom 3 shows huge differences when running without AA and AF but as soon as you turn it on, the X1800XL really begins to close the gap on the 7800GT.
