Introducing Performance Mode in Microsoft Edge | New feature

Updates (Version 91.0.864.1 (Official build) canary (64-bit)):

• Puts background tabs to sleep after 5 minutes of inactivity (if sleeping tabs is on). Timer will go back to its previous selection when you're not in performance mode.
• While we do our best to minimize impact to your experience, performance mode may cause:
  • Videos to be less smooth
  • Animations to slow down when you're not interacting with the browser
