Overview
- Scott Hanselman, who answered critics on X over the weekend, said macOS, Linux and phones already use brief CPU boosts and called the method standard practice.
- In Windows 11 Insider builds, the Low Latency Profile spikes CPU speed for about one to three seconds to speed up menus, flyouts and app starts.
- Early tests reported up to 40% faster launches for apps like Edge and Outlook and up to 70% faster responses for the Start menu and context menus.
- Sources said the bursts are so short that battery drain and heat should be minimal, and testers noted the feature runs automatically with no user toggle yet.
- Microsoft said the boost is part of a broader effort to fix responsiveness, with engineers also tuning legacy code and leaning on “race to sleep” behavior that could help ARM-based PCs most.
