It’s a test bed for the latest unreal engine, but it still performs very well on a lot of different hardware. The switch port likely struggles because it needs to be compatible with the other versions for cross-platform play, so it has to support the same resources (map layout/assets etc) that higher end machines do. There’s a limit to how much you can optimise something when you can’t fundamentally alter it and still keep your other customers happy.
