Not sure why you're downvoted. Even as someone who likes Qt, I definitely noticed that apps like XNView MP load slower than Win32/MFC apps (a few years ago on an older computer though). > nothing outperforms the native libraries in terms of usability. Win32 apps by default have hard-coded widget positions, which can't scale dynamically to larger fonts (though you can try DPI scaling, which is a choice between "blurry" and "text sometimes overflows the hard-coded widget sizes"). Though I don't like how sloppy Qt apps with multiple resizable widgets in a row have strange scaling breakpoints caused by various size policies and [minimum] size hints, and Qt apps tend to stutter when resizing.
