I don't get your point here. What's the problem with high refresh rates? Games deal with it no problem, and they do way more complicated stuff than a UI with a bunch of buttons and text. > Are immediate-mode GUIs up to the task? Yes, there's no reason why imgui's can't do any of that. > What is driving their authors to pursue this design? To name a few: Ridiculous bloat and complicated development with things like Qt. No real GUI framework provided by Microsoft apart of their 4-5 half-abandoned offerings. Also imgui is way simpler to wrap your head around. It's just straight up function calls with no complicated abstractions. > Why aren't they choosing a declarative design? Why should it be declarative though? imgui code looks fairly declarative when you read it and it's easy to understand what UI events cause changes
