Hmm, so what exactly is stored in that gigabyte of tooltips? Even 100,000 tooltips per language should take maybe a few tens of megabytes of space. How many localizations does the editor have?

"Firstly, despite its name, the function doesn’t just set the text of a tooltip; it spawns a full tooltip widget, including sub-widgets to display and layout the text, as well as some helper objects. This is not ideal from a performance point of view. The other problem? Unreal does this for every tooltip in the entire editor, and there are a lot of tooltips in Unreal. In fact, up to version 5.6, the text for all the tooltips alone took up around 1 GB of storage space."
But I assume the 1GB storage for all tooltips include boilerplate. I doubt it is 1 GB of raw text.
