Thought i would post some screenshots of my issue that you could send to the devs about my problem.
Catalyst 15.7 and earlier versions. Crossfire working.
Catalyst 15.7.1 or 15.8 beta Crossfire missing but both GPU's still detected on my PC.
Take note i have done a fresh install of windows as well and did a format in the setup of my SSD before installing Win 10 and i have the same problem.
