If I use limited RGB, every time driver is restarted pixel format goes back to full RGB. It does not matter if it is windows reboot or when I restart driver manually to clear VCN utilization bug (vega8, 3200G).
To avoid unnecessary answers, using newer drivers without this issue is not an option because of severe CPU overhead in some (that I know of) games and performance drop in Borderlands Enhanced for example is 30-50% depending on the area. Even Heaven benchmark is dropping frames at 720p...
