Let me start with what i did when there were settings, which actually allowed you to do stuff.
I UNDERCLOCKED my amd r290 to make my room not feel like a sauna in the summer, all was well, because i didnt need that much power at the moment.
Now i would have actually liked to increase the clocking back to normal, but suddenly the new settings dont allow me to do anything anymore.
I downgraded to the previous driver where the settings were still manipulable, but the settings instead stayed the new way with the added benefit of not being clickable anymore, save for the close button.
all in all i am really happy with the new setting's look, but i don't know why i should ever look at them if i don't have anything to configure.
