Sorry I didn't mention this in the last post, don't know how I forgot it.

When you change the settings in the CCC you have to also save the application profile, in this case you need to save it with the ffxivgame.exe or the CAP settings take over and override your own. They basically say let the game control everything.

When you change settings without saving them to a particular application they only apply to applications that don't have settings defined in the CAP. So just save that profile to the ffxivgame.exe inside CCC overriding all application settings to allow CCC to control things properly.

radeonpro simplifies those steps but also opens up new options that CCC doesn't offer up. Of course the more options you have access to the more risk there is that you'll introduce instabilities.
