Is the New Teams UI just clunky to use? I'm referring to the responsiveness of it. I have it running on Windows Server 2022. Switching between Chat and Calendar takes 3-4 seconds. Switching between user chats takes a couple of seconds. Do others experience this?

Does this happen during the use of the New Teams app, or just initially? Do you have any of these exclusions that may be causing issues? https://learn.microsoft.com/en-us/microsoftteams/new-teams-vdi-requirements-deploy#review-tradeoff-considerations-[…]-testing-for-these-environments AV excluding ms-teams.exe?

It happens under normal use. There are no AV exclusions to my knowledge. There are profile exclusions in place, but the issue isn't after logging on to a server or using it for the first time.

I’ve had a good experience with it on ws 2022. Do you have the hardware acceleration enabled or am I thinking classic teams? Whats your cpu look like?

I think you’re thinking classic Teams. There’s no checkbox in New Teams. There is a json file and according to my file, hardware acceleration is disabled. CPUs on the servers aren’t busy.

What kind of endpoint? If it’s a newer endpoint with arc/iris graphic chipset there are issues with drivers

Endpoint is a Dell Latitude with Intel UHD Graphics running the latest drivers offered by Intel because Dell is still pushing a driver version with the CWA performance issue.
