Same issue with Win 7
Cheers for the reply.
Didn't work for me though.
Really disappointed with this device
I am having the same problem with high cpu often at 100%. Maybe something to do with the new CPU in this NUC5CPYH system.
Running Windows 10. Runs high as you say in chrome etc.
Quite disapointed with performance as it is at the moment.
I ended up selling mine.. Had no faith intel where going to fix the issue.
For others possibly suffering of the same problem. First check your graphics driver version. Open the Intel HD Graphics control panel by right clicking on desktop and choosing graphics properties. Go to the settings and support page and you'll find more information there. Check that the graphics driver is 10.18.15.4256 (that's the latest Windows 10 driver). If less, then download and install new driver for Intel's support page. If you don't have Intel HD Graphics control panel option, you probably don't have the drivers installed at all! In that case, download and install the driver as well.
Unfortunate fact is that the hardware decoding in Firefox and Chrome is implemented poorly and thus they won't be able to handle 2140p, 720p60 or 1080p60 movie clips (there are not so many, but it is getting more common). 720p and 1080p are ok. In Edge all clips that I tried were playable, including 2140p.
YouTube will push VP9 encoded videos to Chrome browsers. You can use h264ify plug-in to force YouTube to serve h264 videos that do have hardware decoder, but even that won't give you more than 1080p.
Comment from a Chrome developer (July 17, 2015): "Unfortunately, at present, our h264 hardware decoder implementation uses copy-back, so it may not work as smoothly as IE in this case (issue 464774 tracks this to some extent)."
What do you think Intel can do to fix this? It's a common problem for low powered CPUs (such as all Braswell), not just the NUC suffers from this. The drivers already enable smooth playback if the application is developed in a clever way.
Check that the graphics driver is 10.18.15.4256 (that's the latest Windows 10 driver). << Yes it has this
CPU still running too often at 100% even doing basic web surfing in Chrome.
Thanks for you help.
