An Unreal Engine app that just renders a Chromium page as far as I understand. Essentially using their own version of Electron made using the guts of one of the most complex game engines. Truly an unholy abomination.

is that why it uses like a quarter of my processor to open the library/store

so a game to open others games

The meme is talking about when the game engine is used to nake things other than games

It’s about using Godot for deskop apps which is overkill but better than electron
