Gaming while watching Youtube performance issue

[statikregimen]

Happy Thanksgiving everyone (prolly wont really get another chance to say it here this year)!

When playing certain(most) games on one screen, while trying to watch Youtube on another, my overall framerate drops dramatically in both applications, often times causing them, and the WM to hang. It was never perfect in Ubuntu (or Winderps) on this machine, but acceptable/stable, so at least I know it can be done.

Changing video quality/size, game quality/resolution doesn't seem to help much.

Turning vsync on in the affected games resolves the problem, but I never had to do that in the aforementioned OSes, and would really rather not enable it in first person shooters (though it's a fine solution for many games, annoyingly).

I tried Compton as a "Hail Mary", and while it did seem to make the system more stable, it did not seem to affect performance (nor the effectiveness of enabling vsync in games). I'm still exploring configuration options, but not sure if this is a rabbit trail or not.

Hardware is more than capable: https://wiki.gentoo.org/wiki/MSI_GT72S-G220 - using a 3440x1440 monitor on the HDMI...so not expecting mind blowing performance, but at least want to achieve the performance I've had before.

Window manager is Qtile.... don't recall having issues in Ubuntu, but could be wrong...I hope not.

Thanks in advance for any insight! Sorry if I've left anything out...

EDIT: Vimeo happens to work a lot better...so maybe a Firefox issue?

Does the NVIDIA GPU is passed through the crappy build in intel gpu and htan to the output devices? Marketed as Nivida optimus and such.

I have used several intel gpu based notebooks, or hybrid ones, and I see microlags, a lot of unresponsiveness, driver issues in windows 10. so in my point of view, the intel gpu is the source of those issues

I play urbanterror with 660m on the internal lvds and watch youtube on VGA with my external monitor. I use i3wm + eudev + openrc. I3wm launches separate x-servers for every virtual screen.

it could also be a setup issue, an issue with a not decent choice of your window manager.

Firefox is problematic recently, I have not watched it in details, but it seems it has issues.

When you game I recommend that you use something slim as window manager anyway, slim and simple

Thanks for the replies!

Well, mpv has not alleviated the problem entirely, but it's 10x better. It's also better for my needs than VLC - no GUI makes it work really well in a tiling WM, so thank you for introducing me to it! Got it set up with youtube-dl (had to rebuild ffmpeg w/ the openssl use flag) and I'm in business. I still have to use vsync in my games, and it's inconvenient to use YT this way, so it's not a permanent solution, but will get me by nicely in the mean time

If someone finds a way to fix it please share it! It would be helpful for sure!
