Similiar issue with the browser client. I observed it eating away 40% cpu doing...nothing? I can't do anything else with my laptop If I want to be heard or understood by others
As someone who uses discord as chat only (if even), their CPU (and partly RAM usage) is simply not excusable. And Audio & Video are not argument for such a bloated client either, well done WebRTC is everything but bloated.
Yet Discord still provides a richer feature set with less browser UI lag than Zulip.
It really is amazing how absolutely terrible the enterprise grade discord competitors are.
At least webex seems to finally have a working audio test button.
