Radeon VII 20.7.2 DirectX 11 Problem

I checked the forum and didn't see this issue listed. I have the Radeon VII with an AMD Ryzen 3950X in an Asrock X570 Creator motherboard, 64GB RAM. Windows 10 build 2004. Up to and including Radeon software 20.5.1 I have DX 11 games that play properly. The game I noticed trouble with is Pinball Arcade using DX 11 interface. Using rev 20.7.2 the game stutters badly is unplayable. I don't know about rev 20.7.1 as I wasn't on it long enough. I do know that simply uninstalling 20.7.2, restarting, and then installing 20.5.1 resolves the issue.


I tried various settings of Radeon Chill, Radeon Enhanced Sync, and Vertical refresh. None of these resolved the issue. Going back to 20.5.1 immediately resolved the problem and the game is back to stable and playable. I have Radeon Chill enabled at 58/65 for min/max, Enhanced Sync Off, and Wait for Vertical Refresh off unless application specifies.


Is reporting this on this forum sufficient for AMD engineers to catch this error report? If not, what place is good for reporting this as this is 100% reproducible.
