It asks that users enable Windows' Game Mode, as well as install and update the Xbox Game Bar App (version 5.823.1271.0 or newer). Some may have disabled or removed these apps previously, but they should follow AMD’s sage advice, as these Microsoft apps work with AMD’s new thread targeting tech to run gaming processes on the fastest cores, while parking the slowest cores if not needed.
Personally I can say having Game Mode on is fine...but having the Xbox Game Bar App is not if you're the type to use, or have, a gaming PC dedicated as an HTPC with Steam Big Picture. Xbox Game Bar App is very invasive when it comes to using big picture and an Xbox controller. Simply toggling off the Game Bar, in Settings, to open when you press the "X"/"Home" button on the controller works until it doesn't and Windows decides to automatically toggle the feature back on its own...it's pretty ridiculous to the point that you either want to use another type of controller (PS/Switch Pro) or go the lengths to literally cripple Game Bar in turning it off indefinitely via means like the registry etc.
