This is a common misconception.
At least with Dear ImGui, all of the actual rendering is performed by the graphics driver, which has a cache.
So, while you may have to queue 100 "render texture" calls every frame, there's no real difference between ImGUI and retained-mode when it comes to the actual frames being rendered.
