"As part of the new driver released for the HD 6800, there were some changes to the image quality options available. Gone were the Narrow and Wide Tent MSAA modes, leaving only the standard Xox and excellent, but performance sapping, Edge Detect MSAA modes. Changes to the Catalyst Application Intelligence (AI) slider appeared as well, with a new Texture Quality slider replacing Cat AI standard or advanced. The new default settings for Texture Quality is Quality, which is not the highest quality mode - there are some optimizations performed, that AMD states shouldn't visibly affect image quality but can increase performance." That link, you know, the one there I posted, if you scroll down, you know with your mouse wheel. Perhaps you can't as you have a old mouse and don't know about that yet.
