Thank you for being a member of the Teams community.

I have tried clearing the cache, but it doesn’t make too much difference.


Disabling the outlook addin actually makes more of a difference.


Yes same here, in Meetings the CPU usage is very high up to 100% and the Teams client does not respond anymore or really slow @Bal_KS 


I have been looking at this for a while and can only assume the issue is with either Electron or MS Teams code. The Teams app doesn't play well with some hardware setups.


I have a low spec laptop and everything is fine, my desktop is way better spec but Teams consumes CPU% when using Video.


I have updated all Teams shortcuts to:


C:\Windows\System32\cmd.exe /c start "Microsoft Teams" /Normal /affinity 6 "C:\Users\your.profile\AppData\Local\Microsoft\Teams\Update.exe" --processStart "Teams.exe"


This command runs Teams and sets it to only use CPU Cores 2 & 3 (I have four cores).


I know this is not a fix but Teams was crippling my system.


I am waiting for MS to release the new Web based desktop client in the hope that it works.
