Last stable driver version 20.12.1 from 2020. The "new" adrenalin 2021 kill the 400 series. PC or card freezes, constant random driver timeouts, bsods. For a while I was hoping it would be fixed, but I gave up. More than half year waiting to the fixing. This adrenalin 2021 one **bleep** and destroy the "old" cards. Ty for nothing AMD
