It's a very good (and new) simulation model. The issue is that it's pretty buggy, and performance is varied. I think there is real potential for it to be optimised into being much better (very poor use of multi core CPU for example), but that's a pretty fundamental rewrite you'd need for that. That it isn't built with DX12/vulkan is again disappointing and I doubt will be something that's addressed in an update, though I'd love to be proven wrong!
It’s probably the best flight sim to date. I see huge potential for addons to leverage the map data. Perhaps an arcade mode to make it more accessible to casual gamers.
Overall maybe, but I'd say the jury's out on the flight model vs X-Plane, and it (currently) doesn't model airliner systems quite to the level of the payware X-plane airbuses or the Zibo boeing. It really crushes X-Plane on weather currently.
