Microsoft will lean on your CPU to speed up Windows 11's apps and animations

Background
Microsoft has heard the complaints about Windows 11 and is working to improve the experience. Throughout the year the company has emphasized its commitment to Windows 11 quality, as noted in a recent Ars Technica article. One of the items on Microsoft’s long‑term roadmap is to boost the performance of core components such as the Start menu and File Explorer.
Low‑Latency Profile
To achieve faster responsiveness, Microsoft is introducing a “low latency profile.” When users open the Start menu, launch apps, or invoke context menus, the system will temporarily request an extra burst of CPU speed. This short‑term boost is intended to reduce latency for interactive tasks.
Testing and Results
Windows Central tested the low‑latency profile in Windows 11 test builds and observed a noticeable increase in speed and responsiveness on the same hardware compared with the public 25H2 release.
Community Reaction
Some users on social media expressed concern that this approach could raise power consumption and shorten battery life, accusing Microsoft of relying on hardware rather than optimizing software. Microsoft and GitHub VP Scott Hanselman responded to the criticism on X, explaining that the low‑latency profile is being added alongside other software optimizations. Hanselman wrote that “everything is a conspiracy when you don’t know how anything works.”
“All modern operating systems do this, including macOS and Linux,” Hanselman noted. “It’s not ‘cheating’; this is how modern systems make apps feel fast: they temporarily boost the CPU speed and prioritize interactive tasks to reduce latency.”

Technical Explanation
Allowing the CPU (or GPU) to use higher power for brief periods can actually save energy compared with running at a lower power level for a longer time. This principle, known as the “race to sleep,” is built into virtually all modern processors. By completing work quickly and returning to a low‑power idle state, the system improves responsiveness while reducing overall power consumption.
