nonissue. nvidia didn't release a big press release condemning this, so there's little point in holding it against amd and no point whatsoever in criticizing nvidia for bringing it up.
Yea, the way I read it... nVidia posted some instructions for reviewers, saying "Hey, take note that when you enable Catalyst AI, they degrade the texture format in some cases to boost performance. If you want to do an apples-to-apples comparison, either disable Catalyst AI, or use this tool to enable our texture format degradation feature in the 260 drivers as well".
