The latest Starfield update has reportedly improved the way the game handles dynamic loading of map cells. While the change didn't result in any immediate player benefits, its very existence suggests that Bethesda may be rethinking how Starfield's map boundaries work in preparation for the recently confirmed arrival of land vehicles.
While all the planets in Starfield are fully explorable, it's not actually possible to circumnavigate them on foot, as their maps are divided into smaller sectors separated by loading screens.
Called landing zones in the game's jargon, the majority of these quadrants span one, four, or nine map tiles. In terms of real-world units, these dimensions correspond to 3x3km, 6x6km, and 9x9km areas.
The exception are corner zones and city regions, which occupy two map tiles. Hitting a landing zone boundary requires repositioning one's ship by going through a loading screen in order to reach another area of the map.
Starfield update 1.11.33, which entered beta on May 1, doesn't change any of these fundamental principles. But what it does do is improve how the game handles loading map cells on the fly, even without the luxury of loading screens.
