Microsoft says Windows 11 will be faster in 2022

WinUI, which is the native UI platform for Windows, reportedly
feel slow and sluggish on some configurations. Windows 11 also
uses WinUI for its core UI components and while they look nice,
sluggish performance is an unwanted side effect caused by the
modern UI elements.

On Feedback Hub and social media
platforms, users complained of performance issues when using
WinUI or XAML UI elements in Windows 11. For example, Windows
File Explorer has been updated with a new command bar and a
more modern interface based on WinUI.

File Explorer’s sluggish performance and buggy experience
is an unwanted side-effect of WinUI. In a Feedback Hub post,
some users noted that their File Explorer just crashes/freezes
randomly and they fail to understand how fundamental components
of the system can have issues.

One user explained: “This is most noticeable when using a
OneDrive synced folder and is still very laggy. Using the F11
option to full screen the Windows makes the experience far
quicker on my install but this is not a valid workaround to
ensure fast performance on such a critical core component of

The whole experience seems sloppy, according to several
reports. Microsoft officials said the company is working on
improving performance in the Dev Channel, with fixes rolling
out in newer builds. For example, a bug where the command bar
was doing unnecessary calculations was recently fixed.

Microsoft to focus on WinUI performance

Additionally, it looks like Microsoft’s UI team is also
planning to focus on performance in 2022. In a Reddit
thread, the software maker promised performance-related
fixes when users complained of sluggish experience when using
WinUI or XAML elements in Windows.

What’s the problem exactly? It seems that WinUI hurt
performance and some have observed noticeable delays when they
right-click on the desktop, try to adjust volume, date and time
popup, notification center, Start, etc.

One user claimed that every classic UI element that got
replaced with a modern version tends to perform slow.

These performance issues have more impact on lower-end PCs as
WinUI and modern UI elements appear to be more GPU intensive.
Fortunately, Microsoft is aware of the reports and some fixes
have already been implemented in the Dev Channel, and more
changes will be tested in 2022.

“Performance will be an area of focus for us in 2022,”
Microsoft said in a reply to frustrated users. “A lot of that
focus will go into startup/launch perf; in terms of UI elements
rendering on the screen (after the framework is loaded), we’ve
tested the scalability of doing things like putting 10k buttons
on the screen, etc.”

Microsoft certainly needs to the sluggish areas of modern
components because WinUI is going to play an important role in
the development of Windows and slow File Explorer or other bugs
can affect the overall responsiveness of the operating system.

If you’ve issues with Windows 11, you can submit the feedback
directly to Microsoft using the Feedback Hub.
