Microsoft is expanding its Low Latency Profile (LLP) feature to all Windows 11 apps with this month's Patch Tuesday update.
Previously limited to the Start menu and native interface, LLP now reaches most apps and Win32 programs as part of the KB5121003 update for all supported Windows editions.
The feature briefly boosts CPU frequency to help apps launch more quickly. The feature uses Microsoft's Controlled Feature Rollout system, so it will not appear on all devices immediately.
How Low Latency Profile Speeds Up App Launches
LLP uses a race-to-sleep approach to handle app launch requests. It temporarily increases CPU frequency to speed up app launches, then returns the processor to a lower-power state.
LLP first appeared earlier this year in the Windows interface and Windows Explorer. The August update now brings it to apps and third-party programs built with traditional Windows APIs like Win32, which could improve their launch times.
After installing KB5121003, Windows Latest confirmed that LLP worked as intended. Standard apps like Notepad and Calculator, web browsers such as Chrome, and the Epic Games Store all opened and displayed content more quickly.
Windows 11 has faced criticism for slower performance compared to Windows 10. Microsoft is addressing this with features like LLP.
How to Get Low Latency Profile and What Critics Say
LLP arrives through the Controlled Feature Rollout system, so not all users will get it at the same time:
- Install the KB5121003 August Patch Tuesday update through Windows Update.
- Wait for the feature to become available, as the rollout is gradual.
- If the feature does not appear, it can be enabled immediately using the ViveTool program.
Some have criticized LLP as a shortcut to make Windows 11 seem faster without deeper optimization. Microsoft VP Scott Hanselman responded that Apple uses a similar approach in macOS and that users have welcomed the change. Race-to-sleep is also standard in Arm chips like Qualcomm's Snapdragon X2 and Nvidia's RTX Spark.
LLP is now rolling out to all Windows 11 users with KB5121003, but the Controlled Feature Rollout system means it will arrive gradually. Users who do not notice faster app launches right away may still be waiting for the update, or can enable the feature early with ViveTool. Microsoft has not announced when the rollout will be complete.
