We are investigating reports that additional settings are not loading for some users. I would recommend using Crimson 16.3.2 or earlier drivers as a temporary workaround.
This has been a problem since the launch of crimson I myself have posted many times about the bugs and crashes of using two GUI's.
AMD you need to implement all CCC options into crimson. How long does it take to complete this task?
If I could offer any advise it would be to either install CCC15.7.1 or try out the RadeonPro mod drivers.
Having a similar problem.
The Radeon Settings open up, but the "Additional settings" tab won't respond. It hasn't responded ever since upgrading to crimson, to be exact. And i've had to specifically make a clean wipe with the drivers every time i want to access the additional settings by using the catalyst control centre with the pre-crimson drivers. That's about the only solution up to date for me...
Or maybe the AMD uninstaller is the problem. https://www.reddit.com/r/techsupport/comments/3wgmk7/amd_crimson_radeon_additional_settings_will_not/ I'll look into this DDU or whatever it is...
I have the same problem since the 16.5.3 ...
When i click on the "Additional settings" tab, it does not pop.... i'm gonna downgrade catalyst to an older version.
Thankfully the latest update 16.7.2 (Beta I think) has rectified all issues I had. This version of Crimson is now giving me all advanced options and also allows the use of some drop down menus that were not accessible in some games.
