Hello ok so I have stumbled across your post but will try to help. The drivers im running I have treat these as final as any newer updates end up clashing or error codes in device manager/ no device present etc
So I have windows 10 + lenovo g505s - 20255. cpu a10 5750m dgpu according to device manager is 8570m (2gb)
so the drivers im running are:
8650g Driver date 26/02/2016 - Driver version 15.301.1901.0
R5 M200/ HD 8500M series Driver date 03/08/2015 - Driver version 15.200.1062.1004
This combination does not have any error code etc. AMD radeon settings - Radeon Software Version
20.11.2 / Adrenalin 2020 always runs on boot up
by clicking preferences, radeon adiional settings the classic control centre loads but its titled radeon additional settings (radeon dual graphics option. colour correction of lcd can be found here etc.)
also I am running msi after burner as there's some settings in there than can be adjusted.
hope this helps. last I remember these drivers were downloaded from oem websites. I cant find the installers on my system
