For Qt that's just not true: you can reach 1080p / 60fps fluid animated UI on small embedded boards such as raspberry pi's. All the rendering is done using a nifty OpenGL pipeline.

To clarify, I was referring to the language choices here. Comparing Lazarus as opposed to Python in the particular case, as well as referring to even worse performance on Electron/NodeJS.

I certainly was not intending to imply that Qt is not performant as it certainly is. Qt is the default UI for Lazarus applications as well, but it does support other UI toolkits (such as Tk) out of the box.
