    hardware acceleration not engaging in Chrome or Firefox or windows media player


      i7 6700hq. Latest official graphics drivers


      Playing 4k video in youtube using Chrome or firefox, cpu usage hits 90%+.

      Hardware decoding is not engaging for some reason.


      Hardware acceleration is enabled in Firefox settings.


      Using Microsoft Edge, cpu is only 3%, hardware acceleration engaging properly.


      It's like the intel igp is not detecting video played in firefox or chrome..


      Also, h264 video played in windows media player will get choppy midway through a video. I monitored the gpu with gpu-z, and HD530 will start at 1000mhz and play the video smoothly, and then all of a sudden drop to 350mhz and have a seizure.

      It just stops hardware decoding randomly.
