Z83-F VP9 videos lag

Hi!
I've bought a z83-f mini pc from amazon some days ago.
I have a problem: this mini pc should support regular broswer navigation, such as playing youtube video. The problem is that a lot of them (1080p and 4k) are in vp9 format and their reprodution is lagged. According to intel documentation, the cpu (intel cherry trail x5-z8350) of this mini pc should support this video codec...so, how can solve this? I've tried also a local play of vp9 video test.
In attach, there are the link for both videos cited above.

Best regards,

Federico

Youtube vp9 video (from about 9:10):
(you can check the code from need statistics)

Here's my BIOS version:

282

Btw, the video in your screenshot is VC1...i've tested the youtube 1080p video above with both vc1 and vp9 (using enhanced h264ify addon):
VC1 1080p@60: lag
VC1 1080p@30: smooth
VP9 1080p@60: lag (not supported framerate according to intel datasheet)
VP9 1080p@30: micro lag

I can send you a video with this tests if you want

We have confirmed that your bios is up-to-date, and try to ensure that no other programs are running during the test, which will increase the CPU load and affect the test results. You can also test the effect of full-screen and non-full-screen.

Microsoft Store provides VP9 Video Extensions appx, please try to install and confirm (Notes:Z8350 hardware can no longer improve performance)
