I have a thread to ask this VP9 cpu usage issue:
Now it turns out that beacuse of Chrome always fail to utilize VP9 in my configuration. So I open a new thread to discuss this issue.
Base on this code(I got this from reddit) :
I have to use this command to tell Chrome to use right VPx codec in AMD's driver configuration:
By this way I have low CPU uasge and smooth VP9 4kfps60.
If I launch chrome from desktop icon link which runs chrome.exe without --enable-accelerated-vpx-decode=2 argument,then I got very high cpu usage and not smooth playing. If I set it to 1 or 3 is the same situation, so it turns out that chrome can not detect AMD's driver configuration on VPx by unknown reason.
Already reported to AMD issue form.
