Thank you for your reports. We released client and service updates this week, that address many MacOS-specific performance issues. We are also aware of recent performance issues with Microsoft Teams meetings, especially on laptops and when using external monitors.
The team is working to resolve these issues. In the meantime, please find troubleshooting information here: https://docs.microsoft.com/microsoftteams/troubleshoot/known-issues/teams-slow-video-meetings-laptops-4k.

I'd like to also comment that Teams performance appears to be getting worse. Today my machine flatlined so badly that the app became unresponsive to turning on an off the microphone and camera.
It appears that it's worse with Big Sur vs Catalina.
Sadly, "other collab apps" do not behave like this and the worsening performance is making its usefulness to me increasingly marginal. I really shouldn't have to use my phone!
Machine Specs: MBP 15", Quad-core i7, 16GB RAM, Big Sur + 27" USB-C monitor.
