Is it possible to use GPU acceleration when playing video in Google Chrome?
I tried playing a 4K video in youtube using Google Chrome, and my laptop was quite laggy. I found out that my CPU usage became 100%, and this was the reason of it. 
I did check the "Use hardware acceleration when available", but the problem still persists.

Contrast to Firefox, when I played the video there, the CPU usage went to around 30-40%, with "Use hardware acceleration when available" settings turned on, and I can watch the video smoothly.

The experiment is done in Google Chrome version 47 and Firefox version 43.

My laptop video cards are Intel HD Graphics 4000 and GeForece 640M LE. Both of them should be capable of playing 4K video smoothly.

[Update]: Even IE11/Edge is also able to play the video smoothly. So only Google Chrome has this problem.
