Factory Reset in Adrenalin is not the same as a complete PC/System reset.
It is a reset of the Adrenalin software only, it removes any existing settings before installing the new driver version. If you have customized anything in the Adrenalin software such as frequency, voltages, fan curves, profiles, game history, etc. it will be reset to default.
This is also an option that can be done at any time (not just during an upgrade) within the Adrenalin settings.
