Microsoft Is Testing a Windows 11 Feature That Maxes Out CPU Speed for Faster App Launches

According to Windows Central, Microsoft is working on a new feature for Windows 11 called “Low Latency Profile,” as part of the Windows K2 effort. This feature aims to make app launches noticeably faster by pushing the CPU core to its maximum boost frequency in very short bursts. Reportedly, this feature boosts the CPU to its maximum frequency for 1-3 seconds, resulting in noticeably smoother app launches during testing. When launching Microsoft applications like Edge and Outlook, known as “in-box” apps, the result is about a 40% faster application launch. Other applications, such as the Start Menu and context menus across the operating system, may be up to 70% faster. Overall, the Windows 11 operating system is expected to receive a significant performance boost, though at the cost of the CPU reaching its maximum frequency.

Currently, this feature within the Windows K2 effort is automatic, with no clear indication if it can be turned on or off. Running a CPU at its maximum frequency is somewhat unusual, as the purpose of an operating system is to minimize strain on the PC, leaving headroom for heavier applications to load. However, since the boost is only applied in short bursts of up to three seconds, it is expected that the performance benefits and overall smoothness will outweigh potential issues. These issues include elevated CPU frequency during lighter tasks and general OS usage, which could result in slightly higher temperatures overall. For laptop users, this might lead to faster battery drain, but it is likely that the Windows K2 effort will account for this, with minimal impact.

This Low Latency Profile feature is reminiscent of Microsoft’s previous efforts when the company started preloading the File Explorer application at startup. Late last year, Microsoft explored this option, which had minimal impact on overall application launch speed. Since Microsoft cannot preload every application on Windows 11, the company is now looking into ways to have the CPU handle the heavy lifting, but only in short bursts that should not be very noticeable to the end user. Many enthusiasts would be willing to accept a snappier experience at the expense of higher CPU utilization for a second or two, provided it is implemented smoothly without significantly increasing the average CPU temperature.
