Even on low power-settings my laptop (and those of many others with AMD chipsets) runs 15°C hotter than on Catalyst, making this driver unusable on the hardware. So what does it matter that there is manual settings if it is still crap? And yes, there is a bug report for it, marked as critical, but nothing happens. I suspect just because AMD is working on power-saving code that maybe will released, maybe not, dependent on what the legal department says.
Catalyst is a must on that machine and if you look at AMD's enormous development speed maybe we will see Wayland support in 3-5 years in Catalyst.
