Yes all well and good for testing purposes only but don't follow the logic behind it because maybe 50% of people are gonna be crossfire.... Just wondering why remove perfectly valid and working OpenGL profiles for apps and games when they actually work better in 99% of cases than including nothing at all with a filesize of 0. ?!? It's just going to lessen performance+cause issues for those in crossfire trying to play with old games n apps and stuff... This is because the caps not only activate AFR for crossfire in OpenGL, they also patch in/restrict OpenGL extensions to work around existing game/app bugs on ATI hardware. Because the implementation of Nvidia's and ATI's OpenGL is different, and so profiled games or apps were developed on NVidia hardware, but crash on ATI without the said OpenGL workarounds. If no profile entries don't exist, then in crossfire they will just crash/perform badly now instead... You may add to the atiogl.xml file (like I have done), but removal of all existing entries for those in crossfire isn't really a favourable option.
