Microsoft tests low latency CPU boost in Windows 11 via ViveTool

Microsoft has begun testing a low-latency CPU profile framework in Windows 11, aimed at enhancing user experience by rapidly increasing processor frequencies during user interactions with system interfaces like the Start Menu and Notification Center. This optimization reduces input-to-render latency, creating a smoother graphical experience. The feature is included in cumulative update KB5094126 but requires manual activation for some users, which can be done using the open-source ViveTool utility.

Empirical data indicates significant frequency spikes during user interactions without affecting thermal performance, making it suitable for portable devices.
