I have the same error message with my Ryzen 7 system and despite Magician version 5.3.1 addressing "Compatibility issues with some controllers", it remains. I wonder how much Intel is paying Samsung for this I don't use rapid mode regardless but no one likes to see these things popping up. Come on Samsung.
who keeps it in the task bar anyway? I had to download it elsewhere, seems the guru3d links are still 5.3.1.
If you have it running or not, doesn't change the fact that it's not pretty and thus odd since effort to make the rest of the UI more sexy have been made.
