Is it "awful" though, or is it just not quite as accurate as X-Plane? Because I've seen a far few videos from actual pilots of various aircraft playing Flight Sim 2024, and generally what they say is that while it's not the same as flying the real thing (mostly because of the lack of feedback for things like trim adjustment) it's pretty damn close. Just because that was achieved by writing specific models for each aircraft rather than full fluid dynamics simulation I don't think that makes it awful.
