With only adjusting the fan curve and taking off Zero RPM, I still get a gray screen crash and reset of the driver just doing work stuff and watching YT. I am running 3 screens, #1 @270hz #2, and 3 at 60hz. Even trying a small tune will result in a crash. Bout to give up on this driver and revert back.
Just remember that 22.5.1 is the last WHQL driver and everything else is beta.
I question your conclusion, AMD drivers are all Beta as no company can be as incompetent in releasing anything like AMD has with a WHQL tag. The WHQL just lets us know that version of the Driver is the one that happened to compile on that day, random luck.
