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.
In the first of our high quality tests, the X1900XTX is even further ahead of the X1800XT when more intensive 3D action is applied.
Here the X1900XTX is 37% faster than the X1800XT.
Quake 4 even with AA and AF enabled is still being bottlenecked by the CPU but the X1900XTX still manages to edge ahead.
