WinUI 3 Performance: A Leap Forward

Wow, they are actually starting to care about quality. Color me surprised.
Almondsetat•46m ago
Don't worry, once enough people come back, they'll roll back in the ads and the intrusive performance-killing features and the cycle will repeat all over again

Microsoft has long had a tick tock cycle for Windows.

98: great. ME: bad. XP: great. Vista: bad. 7: great. 8: bad. 10: great. 11: bad

qzw•32m ago
Maybe “great” is going a bit far for some of those. “Not bad” vs “bad” seems more realistic.
kelvinjps10•25m ago
10 was bad 11 is a little better but no enough. With win10 they started with more annoying ads and the start menu with apps and the click bait news in the start menu
Levitating•18m ago
still leaps better than windows 8
sunaookami•9m ago
Aside from the start menu no, not really. Windows 8 is the most performant operating system. No laggy animations (thanks to DirectUI), fast boot time, especially fast on older systems. Windows 10 started the whole lagfest.
bigstrat2003•1m ago
"aside from the start menu" is one hell of a caveat. When you screw up one of the main UI elements as badly as they did, it really drags the whole experience down.
thewebguyd•6m ago
It was, eventually. In the beginning 10 was literally just Windows 8.1 (it even ran the same NT6 kernel) but with the classic UI slapped back on. They called it 10 to get away from the Windows 8 branding that everyone hated.

I recall it being pretty mediocre at release, just a reskinned 8.1. 10 started to come into its own much later after NT10

contextfree•11m ago
A fundamental problem with this is that "8" is two different releases (8.0 and 8.1), "10" is about 9 different releases, and "11" is three different releases so far (21H2, 22H2, and 24H2). It doesn't make much sense to lump all of them together because they share the same marketing name; technically there's no difference between going from 8.0 to 8.1 or from 22H2 to 24H2 and going from Vista to 7 or 10 20H1 to 11 21H2

I can't downvote this comment, because I've observed exactly this practice happen, again and again, over the past three decades.

I still remain naively hopeful and cheer them on, however.

Anyone who tried to do serious native windows dev has been burnt so often by Microsoft. I really wanted to give them the benefit of the doubt with WinUI 3 but I really cannot anymore. Until proven otherwise I expect absolutely nothing to improve meaningfully. It’s extremely sad for those of us who were dumb enough to think Microsoft take on modern GUI would be interesting to follow closely, we are in 2026 and WPF is still the way to go IMHO.
Rohansi•33m ago
> we are in 2026 and WPF is still the way to go IMHO.

Why not Avalonia? It's not Microsoft but it is a spiritual successor to WPF, cross-platform, and open source.

dgellow•24m ago
Sure, Avalonia is fine. I meant specifically Microsoft offering
jimjimjim•26m ago
Yep, it's 2026 and I'm still 8 hours a day in win32.
brokencode•49m ago
I seriously hope Microsoft consolidates all their Windows app dev on WinUI and invests heavily in making it great.

I also wish that they’d make WinUI work on macOS as well similar to Avalonia, but I think they probably won’t.

jordand•39m ago
There's now an Avalonia back-end for .NET MAUI in preview, so they are making an effort on that cross-platform front too. Link: https://avaloniaui.net/blog/maui-avalonia-preview-1
cosmic_cheese•16m ago
Nice to see. I wonder how feasible it would be to build a plain C interface… would be nice for building bindings to other languages.
the__alchemist•13m ago
As someone who builds desktop apps:

Is there any reason I would use this over something cross-platform like EGUI? I am kind of over software being OS-specific; this is one of the biggest compatibility mistakes we've made. Along with the related process of making drawing pixels on a display a complicated process!

DASD•11m ago
How about F# support? Until then, happy to support Avalonia.
giancarlostoro•11m ago
Will any of this translate to Windows programs like File Manager? Whatever their Image viewer is even called? For some ungodly reason, on my last remaining Windows Device, which is a Surface Book 2 (a Microsoft made laptop!) with very vanilla configurations, everything slows to a crawl in the file manager and if I try to view images on a directory and do the "right arrow" for next or "left arrow" key for previous. It baffles me how something that never had so much slowness can be completely FUBAR'd I miss when Windows had standard apps that were very optimal and didn't slow and ruin my experience. I find myself opening that laptop less and less, and one of these days I might just slap Linux over it.

Did you not read the thread? That's literally stated as an explicit goal.
