Microsoft Tests 'Low Latency Profile' to Boost Windows 11 Responsiveness

Microsoft is testing a new 'Low Latency Profile' feature with select Windows Insiders that aims to improve responsiveness in Windows 11.

The feature works by temporarily maximizing CPU frequency for 1–3 seconds after user input, such as launching an application or opening the Start menu. According to reports, this can lead to apps opening up to 40% faster.

"Apps loaded almost instantly and the Start menu felt more responsive."

Testing and Results

Windows Latest tested the feature on a virtualized Windows 11 install with an Intel 13th Gen i5-13420H limited to 2 cores and 4GB RAM, using a technique from X user Phantomofearth.

Task Manager showed CPU usage spiking to 96% when opening an app, then dropping to 17% after a couple of seconds — illustrating the burst-like performance boost.

Background

• The Windows scheduler traditionally ramps up CPU performance as needed.
• Other operating systems—such as Android's Dynamic Performance Framework and Apple's QualityOfService class—have used burst-like behavior in response to user input.
• The feature is expected to benefit low-cost hardware and reduce microstutters.

Availability

The feature is currently in the Windows Insider pipeline; no general release date has been announced.
