I have a dual graphic laptop, Radeon R7 and Radeon R9 M280x, but the computer only uses the Radeon R7, and I want you to use the R9 for a better video game experience. What can I do to use the r9 graphics in video games and not the r7?
Have you read the 'Switchable graphics' Tut. (link from) AMD Driver Help Portal
Maker sure the power profile is set to "High Performance"
Then follow the directions on this linked page:
