Microsoft recently came out with a new release of Microsoft Teams called New Teams.

Teams both new and old often consumes an exorbitant amount of resources. Especially GPU, CPU and RAM.

In the classic Teams app, you could at least disable hardware acceleration of video streams using GPU by unchecking a box in Settings.

This is no longer possible in New Teams.

Fortunately, there is a workaround:

1. Exit Teams
2. Open the file %APPDATA%\Microsoft\Teams\desktop-config.json (e.g. C:\Users\username\Roaming\Microsoft\Teams\desktop-config.json)
3. Find the setting appPreferenceSettings.
4. In that block, find this property "appPreferenceSettings":{ ... ,"disableGpu":false, ...} . and set it to: "appPreferenceSettings":{ ... ,"disableGpu":true, ...}

If "disableGpu" is not in the list, then add it.
