I have cpu fx7500 quad core with integrated GPU radeon r7 ~786MB and r7 m265 2GB GPu. Also i can t use my dedicated gpu in games.. Configured in ccc on High performance games , all things with performance and stuff done. In device manager, both gpu s are installed. I reinstalled the drivers.. the same issue. Help ,please.
