Broken VP9 hybrid acceleration of Polaris cards using YouTube with Chrome/Edge/Firefox and Windows 10 Creators Update

Hello.

It's been more than a year since Polaris cards release (29/06/2016) and we still don't have proper VP9 hybrid acceleration of Polaris cards using YouTube with Chrome.

 

Prior to Windows 10 Creators Update (April 2017), we could force Chrome by using the command line parameter chrome.exe --enable-accelerated-vpx-decode=2 in order to get VP9 hybrid acceleration on YouTube.

 

Since Windows 10 Creators Update release, ALL AMD drivers are broken and by using the above command line you only get a stuttering unwatchable video experience, not because of performance but because of incompatible decoding with the result of a video stream going back and forth.

 

Two questions:

 

1) Have you seen/ reproduced that broken VP9 decoding of YouTube clips using Chrome with VP9 hybrid acceleration enabled and Windows Creators Update ?

 

2) When are you going to fix it ?

 

Thank you.
