Zoom lagging horribly (180% CPU usage, OSX 11.6.1, Intel Core i9)

Has Zoom been buggy for anyone else? Recently (last month) it's been slowing down for me, and today it got terrible. It was taking up 180% CPU on a meeting; I couldn't use any other processes on my computer and my audio and video were lagging.

This was a normal 3 person video meeting, paid account. OSX 11.6.1, Intel Core i9

I made a community account to come vote this: since the last update I am unable to host a zoom meeting because the whole system slows to a crawl to the point where I have to quit Zoom and use it on my phone. It seems to be ok when I am not the host.

Up until the last update Zoom worked great

MacBook Pro 13-inch 2017

2.3 GHz Dual-Core Intel Core i5

This is key: Not The Host.

400% CPU utilization on a macbookpro 2015 running 12.7 ...and running nothing else. Safemode runs fine but of course no [non-apple] kernel extensions... and no camera capability so.. kinda hard to test that.

This is a major problem

I've exactly the same issue. And I don't have a workaround. Do you have any?

I've been having the same problem and don't know how to fix it

I found a fix by getting the batteries in my MBP replaced; the originals were faulty. Since the new ones, the problem hasn't recurred, although I've only used it occasionally for Zoom after that, as I got a Mac Studio.

I have exactly the same problem. Computer becomes almost useless until the end of the call.

I use the blur background feature which used to work fine.
I use Zoom version: 5.11.11 (10514)

I am having the same issue with Zoom on my 2020 Macbook Air, i7 chip, 16 GB ram, 1 T hard drive with less than half used. In Activity Monitor, kernel_task goes from %CPU of 4.0 up to more than 500 when I try to use Zoom for a meeting I am hosting. Spinning rainbow wheel, have to do a hard shutdown. I have tried Google Meet and get the same behavior. Apple Support blames Zoom, but it is seems to be an Apple problem, if Google Meet causes it, too.

We saw this same problem a couple times, with G-meet during the "Lock Downs" but haven't seen the problem outside of zoom for more than two years. It started happening on a regular basis (e.g.: ALL THE TIME) just in the past week (per this posting).

Well you just have to be patient turn off and on your system it might a minor problem

It happens over and over agaih. I turn off the system, restart, and it happens again. Apple blames Zoom, but it happens with Google Meet as well. So it seems to be an Apple problem, and evidently I am not the only person experiencing it.

And it doesn't happen on my iPad. The problem there is that the iPad doesn't show as many participants as the computer screen, and it has other limitations.

Zoom hanging a lot during meetings since last 20 odd days.

First thing first, is anyone really looking into this ? Because, I haven't seen any responses yet or someone taking this seriously.

Configuration :
MacBook Pro Intel-i7 and 32GB RAM

OS: Ventura 13.1
