Catalyst AI Texture Filtering updates
The Quality setting has now been improved to match the High Quality setting in all respects but one; it enables an optimization that limits tri-linear anisotropic filtering to areas surrounding texture mipmap level transitions, while doing bilinear anisotropic filtering elsewhere. This optimization offers a way to improve filtering performance without visibly affecting image quality
The Performance setting has been updated to address the sharpness of the default Quality setting causing shimmering in certain cases. It now provides a smoother filtering option that eliminates most shimmering while preserving the improved detail provided by anisotropic filtering.
Tessellation Controls
Supported on the ATI Radeon HD 5000 Series and the AMD Radeon HD 6000 Series
New settings give users full control over the Tessellation levels used in applications.
The default selection “AMD Optimized” setting is intended to set the best level of Tessellation on a per application basis. The “AMD Optimized” setting is designed to help users get the maximum visual benefit of Tessellation, while minimizing the performance impact associated with enabling Tessellation. Currently no applications have been profiled.
The “Use Application Settings” option gives applications full control over the Tessellation level.
Users can also manually set the maximum tessellation level used by applications with the slider control
Morphological Anti-Aliasing support for the ATI Radeon HD 5000 Series
