When playing Walheim, YouTube videos don't work well, why?

[Zelus]

I use 2 monitors, and while playing valheim, the video starts to freeze, but when I press ESC, the video works fine. Why does this only happen during the game?

Pausing the game limits FPS to 60, so it decreases the GPU usage, so more GPU can be used to render videos in your browser. It might also be a driver issues, so reinstall your drivers.
Since your GPU is probably utilized to 100% when playing Valheim (list your GPU), limiting FPS in Valheim could potentially improve things for you. You can also test disabling hardware acceleration in your browser (wouldn't really recommend it but you can do it as a test), so that your system stops using GPU while watching videos. There might also be an issue of your system using a wrong GPU for videos, so if you have integrated graphics, try to disable them.
