The generated 3D models of buildings are cleaner and don’t have those odd artifacts. Those artifacts create a lot of vertices and extra polygons to render, which is part of the performance issues some folks have with PG.
The textures here are terribly low res though. So not sure that would be a step up.
And like someone else mentioned, it sounds like this is a BlackShark competitor. Whether or not it runs on Azure is irrelevent. MS have a partnership agreement and contractual agreements in place with BlackShark. They can’t just jump ship to someone else for stuff. Just like they can’t support Jeppessen charts in the new avionics due to their contracts with NavBlue.
