HIGH CPU usage with youtube

  • I've noticed a few times that my laptop is perceptibly hot under my wrists, and checked task manager.

    Despite only having 4 tabs open in Vivaldi and not running anything else, the CPU was at 50%.

    I shut it down, and restarted it, and it appeared to settle down but quickly ramped back up again. It is also taking a huge chunk of memory (about 8 processes totally also ~50%).

    I quickly realised that the youtube tab appeared to be the culprit on both fronts...

    This is a pain for me, as I use youtube a lot for learning to code, and for background music while studying.

    Is there any obvious reason why its having such an impact on resources?

    I read a couple of other threads on CPU usage, and it was suggested that incompatibility problems with the video card can cause resource issues.

    I've included some snapshots from vivaldi://gpu, but I don't really understand the information enough to know if its saying anything relevant.

    My video card is an NVIDIA GeForce 940MX (2gig VRAM) if that helps.

    Strange, because most important for video decoding is green for your gpu.

    CPU usage would be high if you had disabled usage of gpu with vivaldi://flags or by command line parameter.

    Do you use any extension?
    What is shown if you hit Shift+Esc (the process manager) in Vivaldi showing you which process is so CPU costly.
    Do you have a second GPU on your system (some laptops have)?
    Which CPU do you have?

  • I had some analysis on this post
    You can check if same case.
