Most immediate mode does a scene graph diff so it's not that bad

I have a custom IM GUIs based ide thing in C++ that uses like .2% of my 10yo CPU.

Egui doesn't do that. But it's written in Rust and only updates when you interact with it so in practice it's way more efficient than I would have expected.

  • as a side note I absolutely hated writing UIs in egui. It is a really nice framework, but the iteration times were painful.
