Extreme CPU usage of Teams for Mac when using video
Teams for Mac makes the computer almost unusable when using video conference. CPU goes to 100%, teams app slows down, Mac starts fan at max speed making even worse the experience of participating in a video conference (because of the noise).
A fix is URGENT and IMPORTANT, over any other feature.
2020 8 core i9 MBP and whatever codec they're using for video in teams just outright destroys it. Feels like I'm building Windows 10 from source every time I have a video meeting.
Does not happen with any of the other video apps I use: Hangouts, Slack, Zoom, Skype. So is definitely fixable if given adequate attention.

For me, this problem was also very relevant. For example, in conferences at lectures, but we made the decision to turn off the camera when it is not necessary. But still, I would like everything to work well with video communication.
this issue is also on windows, whenever I search it there's literally 1000s of people over the space of the last 3 or so years talking about these issues. I doubt it is ever getting fixed...

Same problem, only when in video call, on MacBook Air M1 16GB. This is a new issue.

I have the same problem. I have seen in intel power gadget (https://software.intel.com/content/www/us/en/develop/articles/intel-power-gadget.html#attachment-heading) that in case i am in a teams video call / conference, requested CPU frequence will be throttled from turbo boosted 4 GHz down to ~ 2 GHz. During the call all other applications and teams of course too have a really bad performance. Directly after leaving the call, the CPU frequence boosts back up to 4 GHz and the system performance ist normal again. All in all you can say, attending a teams video call will throttle overall CPU performance to half and teams itself uses a quarter of remaining CPU ressources.
What can i so, that Intel Turbo Boost will mit be throttled by teams?
Also experiencing similar issues, while running Teams on iPad (Air and Pro) works flawlessly. Will the M1 Mac finally solve this behaviour?

MacBook Air (Retina, 13-inch, 2019) and teams cripple it. can you guys make this software work as expected? I know my company has asked you about it but when will you do something..
Just to echo the previous comments, this is a big deal and should have been fixed years ago. Ridiculous amounts of CPU/power usage. I have tried updates and no change. Sometimes it's a little better, sometimes it's a lot worse. I am also on 1.3.00.24758 so the updates are clearly not fixing the problem

The developer preview helps a little for me, but I'm still seeing extreme CPU use and reduced frame rate in multiparty chats. Reducing the meeting window size helps the frame rate, which seems odd.
I am forced to use Teams for my job (1.3.00.24758). Anytime I try to do a teams video conference using the Mac Desktop, 90-100% or more of my CPU is used, the video and the app itself becomes laggy and completely unusable to the point where I cannot even type messages in Chat and my cooling fan is blaring. I'm worried the heat is damaging my computer and the app keeps freezing. Force Quitting doesn't work and I end up having to forcibly shutdown and restart my computer several times a day. This is literally a brand new maxed out 2019 MacBook Pro, 2.4 GHz 8-Core Intel Core i9 with 64GB 2667 MHz DDR4 and AMD Radeon Pro 5600M 8GB Intel UHD Graphics 630 1536 MP.

THIS FIX SHOULD WORK
(use the developer preview)
It will move you to Teams Version 1.3.00.18164 (developer preview) or later which apparently has the resolution to the issue (thanks Microsoft!)

Same here - if I'm on a zoom call, I can multi-task as normal and I barely notice anything. On a teams call, I can't do anything else on my Macbook Pro - and the CPU fans scream.
I have a brand new MBA 2020 i5 16GB. The basic issue is that MS Teams triggers the Turbo Boost. The MBA 2020 just hasn't got the proper CPU cooling to back up the Turbo Boost. Maybe your Mac also suffers poor CPU cooling. I fixed the issue by shutting down the Turbo Boost of the CPU, using the 3rd party Turbo Boost Switch app. With the TB off the temperature lowers from 100 to 80C, so the fan doesn't go crazy. With the TB off, MS Teams still works fine.
Teams on Mac is a disaster. Performance is awful. A video call brings my 8-core 2019 MacBook Pro 16" and 4-core 10th gen i7 2020 MacBook Pro 13" to their knees with fans screaming.
Having this same issue on my mac. It makes Teams unusable, eats up all the CPU resources and fan is running constantly. All of this stops when I close Teams. Don't have this issue with Zoom or Webex.

I have the same problem. Video on teams constantly stops and I only get audio. And all other applications slow to a crawl.
