> with a razor sharp focus on performance Is it interesting that they chose this phrase. How does it compare to Qt performance on their supported platforms? I cannot believe they will be faster than Qt in 2025. To be clear, I don't think a general UI framework needs to paint GUIs any faster than 60 frames per second. If you need faster, then use a specialist graphics framework, like SDL. That said, the Qt commercial license is very expensive, so maybe they can compete with lower prices (and somewhat lower quality).

SDL is only a graphics framework in that it gives you a window, input events, and either a putpixel/blit functions or OpenGL. It does not have graphics primitives, like what used to be called "glut" in OpenGL itself (but supporting normal platforms, glut supported SGI Irix, BeOS and OS/2, but felt that Win32 was too niche to care about, and they never voluntarily cared about linux). Like even now it seems to think that this whole IOS and Android kerfuffle will blow over soon, not worth any effort. SDL is like a (much better) glut that has sane platform support (and audio). PanGUI gives you graphics primitives, nicely done and executed and seems to have a much saner selection of platforms (and also gives you audio), as well as supporting a great many languages to code in.

    I didn't talk about Qt at all. But yes, I imagine Qt can easily do that, and you probably can get it going with LGPL Qt, but it's not going to be easy to avoid the commercial license. I hope PanGui can do better in this regard.

Seems artificially constrained. The vast majority of devices today are >60fps.

  Uh, No? I agree that most >$600 phones are >60hz, as well as a lot of mid-to-high-end laptops (>$800), but that's not even remotely close to the vast majority of devices. I also agree that nobody should limit it to 60hz though, but the global percentage of people using >60 Hz is likely single digit

    Fair, I should have said greater than or equal to 60fps. CRTs could handle at least 60fps, and I'll be impressed if you can find a <60fps device for sale in the past decade.

  The "vast majority" of devices that Qt targets today are <= 60fps. Somewhat unrelated: Are there any desktop apps that needs >60fps? I see no business value.

    Do you have a source for that? I've been struggling to find any hard data. What apps benefit? Anything motion heavy. https://www.testufo.com/ https://www.testufo.com/ Need might be a strong word, but that's my point with "artificially constrained." Reminds me of the potentially apocryphal Bill Gates quote: > 640K ought to be enough for anybody
