ATI Catalyst 7.4 Performance Analysis (Windows XP) - Benchmarks - High Quality AA and AF

Catalyst 7.4 release came early, but with only a single noted performance improvement, should we rush to update?

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 normally use 4 x AA and 16 x AF as this is quite a common setup for most people who are venturing into the AA and AF area.

 

 

Cranking up the AA and AF we can see that no difference in performance is seen.

 

 

The increased load onto Lost Coast shows us no performance difference.

 

 

The only form of performance increase we have seen in the whole driver set comes with a bump in performance from the X1950XTX in the OpenGL based Prey.
