I wasn't talking about actual gameplay but the technology used to create space, planets and surface because mojonaut said 'they have already solved seamless space-planet transitions' which sounds like it's something FDEV couldn't or didn't solve. The engine itself has no problems with seamless planetary landings, but they put an additional layer on top of it to allow instancing which kind of makes them non seamless. There are some dev videos showing the capability.
Even with the transition you can drop out basically instantly (a few ms), sadly the servers are limiting this experience most of the time.
So what? The engine is capable to AI wingmen and NPC crew but they're not in the game. Pauses in the change from SC to Normal space to planetary services are not seamless.
But it can be. You can fly from planet to planet or planet to station in normal space. It would just take a long time.
I'll quote myself here
So it's not seamless for the vast majority of users. I get that it can be seamless if you play the game in a way that no one ever does.... but there's a definite seam between Normal Space and Super Cruise.
