While you're waiting for a proper fix, a temporary workaround would be to create a desktop shortcut for the games you need a profile for. Radeon Settings should then find them when you click on Scan. Had this happen when I migrated my steam library over to a clean windows installation.
I haven't done any digging into this but I'd hazard a guess that it might be (in my case) due to Steam being installed to a non-default location (my K:/ drive).
Interested to see the proper fix. I've too many games to give them all Desktop shortcuts.
I had desktop shortcuts for at least a couple of games, including battlefield 1, battlefield 4, Mass effect... The first two, including the origin installation, were installed on my boot drive. No profiles were generated at all...
Is this problem happening to you too?
An update: yesterday I installed playerunknown's battlegrounds. Running scan from the AMD drivers did find this game. Nothing else though. For example, my boot disk-installed BF4 is not detected at all. Same thing with all other games. Only PUBG is detected.
