Zoom is using <10% CPU on Windows and 125% CPU on Linux. Why :/

    Random stuff on Linux, discord uses around 80% on mine but on windows around 5%.

    Just Linux bring Linux.

    You may also notice it won't shut down properly and keeps spinning after ending calls, the background threads keep running and the UI can't be restarted. My zshrc has a "killzoom" function which just pkills it.

    Bear in mind though, windows perf monitot reports cpu usage differently than *nix tools, so that's part of it as well.

    They don't put any effort into it because of small userbase.

    Discord seems to behave better on my systems

    @SortOfTested lucky you, maybe is a Debian distros thing.

    Have you tried both the .Deb and flatpak distributions?

    haven't tried the flatpak, maybe one last try.

    Only during calls or always?

    @sbiewald only during calls, the rest of the time it's fine.

    How many cores do you have? 10% overall usage on my desktop would be 160% as I have 16 cores/threads

    @guitargirl15 probably a software vs hardware decoding issue.
    Windows might have better drivers for your video card to allow Zoom to offload some tasks to the GPU.

    @kwilliams exactly what I was thinking with those numbers. Though I don't think it's a driver issues but application not using it. Chromium based browsers suck at Intel based gpu for example. Firefox no issue.

    @eptsousa Isn't Discord based on electron? Which should make this less of an issue??

    @JFK422 I think precisely the whole problem is electron IMO, but yeah I’ve tried in a few Debian based distros and no luck, maybe my hardware is a problem which wouldn’t be the first time.
