You need to update the next Driver with a general Crossfire settings for Radeon 7990HD and all the other Dual/Crossfire GPUS. I can't run any Xbox App games via Windows 10 with Crossfire enabled because there is no setting to enable Crossfire on Crimson Profile "Global Settings". Only way to enable Crossfire is for Games with a Gaming Profile and Windows Xbox Store games are locked and encrypted, making a Gaming Profile is impossible with games like "Forza Motorsport 7". Pleas FIX this Crimson issue for Crossfire settings on Windows 10 Xbox Store Games Soon! I Really want to run my Radeon 7990HD and i don't want to buy another Card! Please Update Crimson with a Crossfire Global Settings!
Thanks, I am really looking forward to playing some Great Games on Windows 10!
