I have problems with dual graphics since I upgraded to Win10. I have Radeon R5 graphics and Radeon R6 M255DX both with the latest same driver version 15.200.1062.1002. I've noticed problem when I tried to play game Football Manager 15 on High performance mode (external Radeon R6 M255DX card), game froze with the whole laptop and I had to restart. When I set the game to run on power saving mode (integrated graphic card Radeon R5) it works. What could be the problem here? How can I check if my external R6 graphic card is working correctly?
