I am running windows 8 developer preview on bootcamp with my late 2011 macbook pro (Radeon 6700 card I believe). I can't get the brightness to work correctly. I HAVE tried turning off adaptive brightness. It is not the same issue. No matter what set of AMD display drives I download, my brightness level only maxes out at about half of what the screen is capable of. I can fix this if I disable the amd driver...but obviously I don't want to do this. Any ideas on how to fix this?
