Anisotropic Filtering Performance

When testing the performance of ATI's different Super-AA modes a couple of pages back, we stepped through each successive level of AA while benchmarking FarCry and Half Life 2 at a resolution of 1280x1024. The results on this page were attained using a similar methodology, but we altered the level of anisotropic filtering being applied to the images instead and used FarCry and F.E.A.R running at a much higher resolution. Anti-aliasing was disabled throughout this batch of tests to isolate the effect anisotropic filtering alone was having on performance.

ATI Anisotropic Filtering Performance: FarCry & F.E.A.R.
Sharpening Up Those Textures

 

 

As we demonstrated on the previous page, ATI's high-quality anisotropic filtering modes offer arguably the best anisotropic filtering available in a consumer level graphics card. And the performance data on this page shows that there is virtually no reason to have it disabled and use the lower quality setting. ATI's high-quality aniso modes perform just barely below the comparable "standard" modes in both games, and have a minimal impact on performance versus just using trilinear filtering.
