I have installed Linux Mint 18.2 Cinnamon (kernel: 4.10.0-32-generic)
on my new ASUS UX430UA notebook
. It has Intel Core i5-7200U
, integrated graphics only - Intel HD Graphics 620
and 8 GB of operating memory.
I noticed that when I'm playing YouTube video, even when it is minimized, it has high CPU usage - around 40% of each CPU core with 720p@25 video. Compared to my previous notebook - MSI GE60 2OC with Intel Core i5-4200M it is four times more. Intel Core i5-7200U should be even a bit faster (tried benchmarks proven this to me).
What I tried:
- different web browser - all have this issue for me
- check CPU throttling
- custom compiled Chromium from public repository with forced HW decoder (also set in chrome://flags) - in chrome://media-internals was written that I am using HW decoder
- install recent intel-microcode
- try different Linux distribution
Is it normal with this configuration (which I don't think) or can you tell me what I am missing?
EDIT:
All tested web browsers runs very strange in this issue. When I launch them first time after boot and load page with video from YouTube, CPU usage stays about 40 seconds of video playing at 5% per core. After, it increases to 40% per core. Then even when I launch any others web browser or the same one again, playing video consumes 40% of each core usage. No web browser background processes are running by my research.
EDIT 2:
It seems that installing i965-va-driver
package helps with playing videos with local video players as xplayer
and more effective with vlc
. Strange is that my old laptop MSI didn't require installing something like that and plays videos with local video players even a bit more effective (lower CPU usage) - I don't think that in LiveCD OS uses a dedicated GPU (in my case Nvidia GT750M) for HW video decoding. Installing that package also helps a bit with playing videos on YouTube with custom compiled Chromium with forced HW video decoding, but I believe there is still much to improve.
I hope that this all is caused by newer hardware and it will get some support in this area later.
