Have you set Windows Update to delay/pause checking for updates or installing updates? Do that and delete all drivers in C:AMD folder. Reboot.
Can you clarify what the problem is:
Relive stops working at all with fresh installed driver after a pc restart (you can't enable recording anymore)
When recording with relive and alt-tab out and back into a game you get stutter and lag untill you disable recording/restart pc?
After tabbing out ReLive wasnt able to capture and microstutting starts again like in the video link in the entry post. All overlays didnt not work anymore (performance metric overlay, Radeon Software Menu (Alt+Z, Alt+R)..) and also after reboot the result was like that.
I can only use newer drivers than 20.3.1 without ReLive, ReLive is working after CLEAN FRESH INSTALLATION until it interrupts once.
