I run Kodi in 4k@60fps and I don't think its a heat issue.

here are my measurements:

Code:

/sys/class/thermal/thermal_zone*/temp output
normal
68c
53c

After echo 750 > /sys/kernel/debug/dri/0/i915_min_freq
71c
56c

Its stable.

 It absolutely makes no sense that it gets slower after setting the minimal frequency to 750. Normal minimum is 200. 750 will just make sure it does not reduce the clock. 

 I understand that it makes no sense. At best setting the frequency did not help anything. The temperatures are almost the same and the framerate is the same-ish rubbish. I could post a video tomorrow if it would help anything but I doubt it will. Is it only my NUC6CAYH that is having these troubles with 10bit 4k video on the newest builds?  @blokkie  ??
