The GP was talking about Unreal Engine 5 as if that engine doesn't optimize for low end. That's a wild take, I've been playing Arc Raiders with a group of friends in the past month, and one of them hadn't upgraded their PC in 10 years, and it still ran fine (20+ fps) on their machine. When we grew up it would be absolutely unbelievable that a game would run on a 10 year old machine, let alone at bearable FPS. And the game is even on an off-the-shelf game engine, they possibly don't even employ game engine experts at Embark Studios.
