    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 did a fresh install of Big Sur on Monday and things were working ok for a few days. Now Teams meetings with multiple users and shared screens are killing my CPU (kernel task 550%, teams 250%) and GPU (RADEON PRO 555X at 100 processor usage) again. I only get the issue when I'm plugged into a 4K external monitor via my CalDigit TS3 Dock. It tends to improve for a period of time bit after I reboot.

    I've not disabled GPU hardware acceleration or turn off new meeting experience, and upgraded to 28778 and the CPU performance is now worse for me. I can't interact with any other windows while Teams is running with presentation. Basically the UI and locks up.
