Cyberpunk has had a lot of work done to fix it.
Starfield on the other hand is sharply limited by the game engine and might not be fixable at all.
Turns out that Bethesda use a fairly standard floating point coordinate system, but set the origin to your ship, so if you go too far away from your ship, the game will flat out crash. So exploring is not recommended in the game that was marketed as being based on exploration.
Isn’t that the same system Minecraft used that made the world generating really weird when you get really far away?
