I have VPx enabled on Chrome version55/64bit ,but still have high CPU usage,VP9 Hardware accelerated seems not working(DXVA Checker can not detect any dxva session).

Sample video:


Very high CPU usage(4k FPS60,I have to disable h264ify to see this option):



CPU: Intel E3-1230v2

Motherboard:Gigabyte B75M-D3H rev1.2 /BIOS F15

RAM: 20GB DDR3 1333 RAM

GPU: Powercolor RX460 2G

OS: Windows 10 64bit 1670

Driver: Crimson ReLive 16.12.1

Display: Benq GL2450 1920x1080@60Hz DVI


Any suggestion or this is a bug?

Or the video is not VP9 video format?
