📰 Full Story
Microsoft is testing a new “Low Latency Profile” in Windows 11 Insider builds that briefly ramps CPU frequency for one to three seconds to prioritise interactive tasks and improve responsiveness.
Early testers and reporting from Windows Central and other outlets say the boost can make built-in apps like Edge and Outlook up to about 40% faster and speed Start menu and context-menu interactions by as much as 70%. The feature triggers on high-priority UI actions such as opening apps, menus and flyouts.
Microsoft executives, including Scott Hanselman, have defended the approach as industry-standard behaviour also used by macOS and Linux, while some users criticised it as a band-aid for deeper performance issues.
Reports indicate the short bursts have minimal impact on battery life and thermals, and Microsoft is still refining activation frequency and duration; it is unclear when or whether a user toggle will be provided.
The change is part of broader Windows 11 work to improve performance and streamline the UI.
