stuff to work with more continuous travel.
I bet you would be surprised if you were to find out that it is possible already. In space one can already move from one planet to another, only thing that is missing is the loading of new space "map" on demand. And more importantly move from one planet to another and then dock with spacestation. As shown by https://www.nexusmods.com/starfield/mods/3541.
And on planets the landing zones aren't placed in a vacuum, topological details like mountains are visible from adjacent zones. As shown by https://youtu.be/Fy0eG7MFSTM?si=ZwaE3OzmEf9IxbwZ&t=841 by 2kliksphilip.
Now you might ask the very obvious question: why isn't this correctly implemented to allow seamless travel in both space and on planets in vanilla Starfield? We may know only after someone does full introspection what happened during development but my speculative guess is that Xbox Series S which is much weaker than X is the primary reason for all this segmentation in all aspects of Starfield.
Speeds that the above mentioned mod adds. Until CK is added the debate of switching of one space map to another seamlessly is useless, since the current implementation is missing the hook to load the next map whilst the same hook is implemented between ship take off and space (even when player is not at the helm). Yeah, but New Atlantis is much bigger and allows the player to boost pack from the MAST top floor to another skyscrapers roof and then get down to commercial level and trade stuff without any load screens, at least on PC.
Expect of course if there were dev stories related to it sprinkling out periodically, latest being from Baldurs Gate 3 devs: https://www.pcgamer.com/baldurs-gate-3-dev-shows-off-the-level-of-optimization-achieved-for-the-xbox-series-s-port-which-bodes-well-for-future-pc-updates/
Other devs have stated these: https://www.gamesradar.com/xbox-series-s-could-bottleneck-some-next-gen-games-developers-suggest/
The article has many such remarks from other devs as well. So why couldn't the segmentation of Starfield be because of Xbox Series S? Keep in mind the latter article is now roughly three years old.
