to make additional settings work you must install a catalyst driver and then install crimson 16.3.2 and that is it.
Note: You have to NOT uninstall the catalyst drivers instead just install the crimson drivers without doing anything to catalyst.
What I would try is removing the drivers in safe mode using either DDU or the AMD Clean Uninstall Utility. Then install the 16.6.1 Crimson Driver.
You may want to add your info/error/s, and follow for when fix is announced.
Try using 16.5.3 and this method Clean Install AMD Graphics Drivers
