High Quality AA and AF
In our High Quality tests we bump the Antialiasing (AA) and Anisotropic Filtering (AF) up causing the cards to be put under more load. This usually helps us remove the CPU limitation.
We'll 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.
High quality tests show very little performance gains.
Again with AA and AF enabled, Far Cry sees no performance increase.
