Video lag vbox guest

There is video stutter when watching youtube videos.
On host it works fine .

Any workaround for this video lagging.

Hardend settings are used same as in doc

3d accel=off
Video ram 128= max setting

Slow Video Playback

sudo apt-get install vm-config-dist on guest output

dracut: dracut module ‘nvmf’ depends on ‘network’, which can’t be installed_

I would set render but i dont know how and where to set this command .host or guest?
QMLSCENE_DEVICE=softwarecontxt

Host gpu
glxinfo | grep OpenGL
OpenGL vendor string: Intel

Still, nothing helped even 3d enabled
The only solution would be to use host for vbox and youtube only, nothing else.
But host firejail blocks internet on kicksecure guest.

Installed by default inside VMs. Don’t do this on the host.

Ignore.

Documentation does not say "do set QMLSCENE_DEVICE=softwarecontxt.

No context change.

  • If starting application inside VM, change environment variables inside VM.
  • If starting application on host change environment variables inside host.

Alright,

but due to weak cpu and ram i stick with host only for youtube as it plays 1024p smoothly with silent fan, in addition with sandbox app launcher .

For safer way i will consider kicksecure as host for youtube instead of debian + vbox for webtasks.

If any related docs to this case feel free to post them .

I didn’t know that’s Linux related issue
why?
On Windows 10 guest YouTube works very well same as host even with 3d accel disabled .

Can someone explain more why zero video stutter on win10 compared to kicksecure despite the same vbox settings

Internet search term:
linux graphic card driver performance vs windows

But this difference is noticable on vbox guests only
Linux vs windows on bare metal no difference .
But on vbox linux is disaster

Can u give another search term
