Yeah, things are not working great on the 20.x.y drivers, we have some more testing to do there. 18.6.1 is our old favorite, 19.11.3 has been used by beta testers without issues as well if you want to be able to control clocks in e.g. OverdriveNTool only. For the 20.x.y range, I have some users mining on 20.4.2, but that is on VIIs and not older Vega 56/64, I'm not sure if it's significant.

I will soon set up a better windows rig to do some serious driver testing.
