How to Enable the New Low Latency Profile Feature in Windows 11

 Microsoft is developing a "Low Latency Profile" feature for Windows 11 as part of the Windows K2 effort, designed to dramatically speed up app launches by boosting CPU cores to maximum frequency in short bursts lasting 1-3 seconds. Though in testing phase, you can turn on this feature right now.

 

Microsoft hasn’t announced the Low Latency Profile feature, but early indications of the capability have already appeared in Windows 11 preview builds. Users interested in testing this unreleased feature may be able to access it through ViveTool.

How to Enable Low Latency Profile Feature in Windows 11

1. Download the ViviTool zip file from GitHub and unzip it.

2. Copy the path to the extracted folder.

3. Open Command Prompt as administrator.

4. Enter the command cd c:\folder\path\ViveTool-v0.x.x and press Enter (replace the path with your actual folder path).

5. Execute the following command to enable Low Latency Profile: vivetool /enable /id:60716524,61391826

6. Restart your PC to apply the changes.

7. To undo the changes, execute the command vivetool /disable /id:60716524,61391826.

Upon completing these steps, the command will activate the “LowLatencyProfileForApplicationLaunch" flags throughout your operating system.

Note: I have tested this with the Windows 11 Release Preview build 26200, but haven’t noticed any improvement. 

According to various reports, the testing shows approximately 40% faster launch times for Microsoft's built-in apps like Edge and Outlook, with system elements like the Start Menu and context menus seeing improvements of up to 70%. The feature operates automatically with no current user control option available.

Limitations of Enabling Low Latency Profile 

However, this approach sacrifices some power efficiency for performance gains. Running the CPU at maximum frequency during lighter tasks will increase heat output and, on laptops, accelerate battery drain. 

However, since the boost only activates for brief 1-3 second bursts, the performance improvements are expected to justify these trade-offs, with minimal overall impact on system strain and thermal management.

This strategy represents Microsoft's shift away from preloading applications at startup, an approach the company tested previously with File Explorer but found to be ineffective. 

Instead of preloading every app, Microsoft is leveraging the CPU itself to handle the initial workload more efficiently through temporary frequency boosts, aiming for a noticeably snappier user experience without substantially increasing average operating temperatures.
