ATI Catalyst 6.5 Performance Analysis - Benchmarks - High Quality AA and AF

Yesterday ATI released their newest set of Catalyst drivers and we take our usual look at the performance changes.

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.

 

 

Across the board performance is the same except the X1900XT has taken a very easily spotted dip in performance.

 

 

Far Cry hasn't seen anything exciting to report about.

 

 

While the mid-range cards saw an increase in performance in Quake 4, when we turn on AA and AF performance was almost exactly the same across the board.
