Okay. I've gone through this thread thoroughly. The problems that're mostly observed while using AMD's Crimson drivers are: 1) Fluctuating core clocks while running GPU intensive 3D applications & games. 2) AMD's newly built Crimson control panel crashing on startup. 3) Overdrive settings and other changes made through the UI not being saved and is being reverted to default or a troublesome value upon restart. 4) Random artifacts observed in games that goes away when certain resolutions are used. 5) AMD promising a lot but yet again under delivering as usual, so what else is now? We know by now that this new QT GUI is nothing but a diversion which broke more things than it fixed.
