--- Comment #2 from Mike Lothian mike@fireburn.co.uk --- It's not a regression, you'll need to get a kernel from drm-next (with amdgpu.powerplay=1 set) or a kernel from the powerplay branch in order to get your card to clock to its maximum frequencies during gaming. Equally you could wait for kernel 4.5-rc1 to be released
