Time pauses when editor window is inactive

I know this is a setting in editor preferences or project settings, but I can’t remember what it’s called.

I want the time to run continuously even when I am not actively within the editor window.

My editor defaults to pausing time when I click out. I want to see UV’s panning, media players playing, flipbooks flipping, etc. when the editor is not the active window.

Please advise & thank you.

Maybe it’s this, in the editor preferences:

Use Less CPU when in Background

There’s a separate flag for audio, too.

On the top left of the Viewport is a down arrow, in that menu is a Realtime check box, might be what you are looking for.
