Windows 11 is finally starting to change for good.
Microsoft is testing system app performance improvements on Windows 11, highlighting the Native WinUI 3 that is the new version of Windows' core UI framework to make apps open faster, respond more sensitive, and use fewer resources.
.
Microsoft previously unveiled a Windows 11 performance upgrade plan under an internal project called "K2," with the goal of improving the overall system in speed, fluidity, usability, and extracting more potential from hardware, such as the Low Latency Profile or LLP feature, that allows the system to use CPU boost clocks more efficiently, and prepare to support AMD's "highest frequency" CPPC feature in the future.
.
Most recently, Microsoft has revealed its progress through GitHub that the WinUI team is improving WinUI 3 as a leap from WinUI 2, clearly aiming for the new framework to perform better than before, in line with the approach Microsoft executives once stated that Windows 11 is moving towards being "100% native."
.
In the initial test, Microsoft used apps like File Explorer and Notepad as a measure, especially File Explorer, which started to see interesting results such as 41% reduction in memory bookings, 63% reduction in transient allocations, 45% reduction in function calls, and 25% reduction in WinUI code time during app opening.
.
Microsoft has indicated that these improvements will soon be moved from the development branch to the main branch of WinUI 3, and some may be implemented with WinAppSDK 2.x if possible. However, some tweaks may cause breaking changes, so it will be open to both developers and users to opt-in early.
.
This move reflects that Microsoft is not just relying on newer hardware to make Windows 11 faster, but is taking direct action to improve the underlying software and framework of the system, which may help Native apps on Windows 11 become more sensitive, more slippery, and consume fewer resources in the future.
