I have a Aspire E15 E5-553G-12C6; A12-9700P, Radeon R8 M445DX. I've install the latest Radeon software and it still doesn't solve the issue, but instead register a driver for Radeon R7 M340. Also the crossfire function isn't working properly because the graphics is very slow when playing very basic games and it doesn't seem to be using the discrete graphic card. I've set everything to performance and even in the display/graphics settings added the game/program and set it on performance. In the Radeon software I've enable crossfire too.
