Since my switch to manjaro I’ve noticed some very low video playback performance once my CPU utilization goes above 40 or 50 percent because of other processes. The video starts to stutter or freezes completely while only the sound is playing. In other instances the video plays but the sound starts to stutter. Which shouldn’t happen because non of my system parameters are anywhere close to being maxed out in this situation. Disk read is low, load is currently at 4 (with an 8 core CPU) and my cores are running at 40-50% each but I can’t play any video (neither with vlc or mpv). CPU usage and load also doesn’t peak while trying to play the video. Are there any other tools besides top and System Monitor that could help me figuring out where the bottleneck is? Or is this a known problem (maybe because of some missing drivers or missing hardware support)?
I’ve installed manjaro with propritary drivers. I’m running on an i7-6700 with an GeForce GT 710 (driver=nvidia; there is also a second card, but that is used exclusively for virtualization and shouldn’t be used by manjaro at all).
provide formated output from:
inxi -Fazy
mhwd -l && mhwd -li
also try this:
its probably pulse/pipewire issue… install this package: manjaro-pipewire - it will give you dependency issues, so uninstall them first, then instal again the manjaro-pipewire package, reboot and check
Hmm, installing pipewire didn’t solve the issue (and seems to have problems putting out Digital Surround 5.1 which is stuttering everytime - Digital Stereo works fine.)

nvidia temp: 69 C
Are you playing a game right now, is it really hot in the room you’re in? Is it time to dust the inside of your desktop? Why is the nvidia temp so hot? Mine hovers around 29-30C with regular (when not gaming) use.
so uninstall pipewire if you have issues with it, and install pulse with: manjaro-pulse - it will automatically remove pipewire…
also noticed that you have only nvidia drivers installed even though you have also intel graphics, so install it with:
sudo mhwd -i pci video-linux
reboot

Maybe 800Mhz are not enough?
Thank you all for your observations!
That is only while idleing - when used it goes up to 3700 what should be normal.
Are you sure this might be a solution? The intel graphics are the onboard chip that came with the system but I don’t use it and the output is not connected. I’m just using the two nividia cards. Of cause I would be willing to try it, but I’m not particular fond on installing additional drivers for unused hardware because that tends to cause problems.
That is indeed a good observation. I will check on that. One is a fan-less card in a small tower, so this one might be running a little warm, but it stays still well within the manufacture specifications even when under stress. I’m not sure for which of the cards this reading is, because the one with a fan is used for the virtual machine and shows way lower temperatures when used. But than it shouldn’t report a fan speed. But I don’t think this is the problem, because I didn’t change any hardware since switching to manjaro four weeks ago. And the system handled the video playback fine while I was still running Ubuntu.
Edit:
According to nvidia-smi this is indeed the temperature of the fan-less card that for some reason also reports a fan-speed?!?
you can try ‘tweaks’ from this link and see
Are you sure? governor: powersave means: stay always at the lowest clock speed, but sure if a program asks for speed, then the governor changes, for example with gamemoderun.
Same readings while playing a video:
Speed (MHz): avg: 1076 high: 1200 min/max: 800/4000 scaling:
driver: intel_pstate governor: powersave cores: 1: 1200 2: 1200 3: 1200
4: 1200 5: 1001 6: 1179 7: 800 8: 834 bogomips: 54417
…and while running the processor at 70% capacity
Speed (MHz): avg: 2204 high: 3405 min/max: 800/4000 scaling:
driver: intel_pstate governor: powersave cores: 1: 3405 2: 3100 3: 3100
4: 3100 5: 840 6: 800 7: 967 8: 2324 bogomips: 54417
I think this looks good or do you disagree?

Interesting, so powersave on the intel_pstate module acts like conservative on the acpi-cpufreq module. So it clocks down to lowest possible speed, but clock up if needed.
Good to know that 
What videos are we talking about? 4k or 2k videos? There it doesn’t matter how high the CPU usage is. Without GPU acceleration it will always stutter.
This link does not work anymore (error: Name not resolved).
