I have a 6900xt after installing 22.3.1 I looked under the tuning tab I was shocked to see it had custom under manual tuning check-marked. I have never done manual tuning I always just set it on rage. Was this part of the update or an issue?
Not sure what happened. Did you have 'keep settings' checked when you installed the driver? If you reinstall the driver and perform a factory reset and uncheck keep settings, you should be able to start over fresh with default settings.
I downloaded and installed the driver in the adrenalin edition application. It never asked me to keep any settings or not that I saw. Just download then install.
