if you don't want the vp9 video function, try 'h264ify' for google chrome.

"chrome 目前youtube 貌似用vp9 的htm5解碼,目前沒顯卡可以硬解"
不正確...
nvidia PV-vp7 support vp9 decoding...

for intel solution, only skylake or later does support partial VP9 encoding and decoding

"Edge 播youtube 應該沒支援到vp9,所以會比較順"
Starting with EdgeHTML 14.14291, the open-source WebM container format and the VP9 video and Opus audio codecs are supported in Microsoft Edge.

By default, 'media format with vp9' setting is automatic..
if you want it..
1. about:flags
2. set 'enable vp9 video format' as 'always on' to force vp9 video function enabled...
