Drivers from the Crimson package have killed my FPS in WoW. Have gone from at 42fps to 10fps. This is unacceptable.
Clean Install AMD Graphics Drivers
If you for some reason don't feel comfortable with DDU & safe mode, I believe that the Crimson uninstall routine defaults to "remove all versions" of the driver when you run it, which removes all AMD GPU drivers from the system, including the presently installed Crimsons and any past-installed Catalysts that may still be there. There is a "Change" button right beside that description, that, when you hit it, changes the default to "current version only" which removes only the currently installed drivers--the Crimsons, in your case. I used it before I reverted to the Catalyst interface and it seems to work as advertised.
I think you've just might gone from a dGPU to the iGPU..
