Well it still needs to simulate some things of the NPCs you can’t see. Since those still affect things like weather, world economy, politics that will influence what the player character sees and interacts with.
Yeah but all of that can be abstracted. Instead of simulating down to the atom, if e.g. a plant is out of FOV, you can just run a probability table for its properties and functions. Things like alive or dead, quantity of co2 and water consumed, o2 produced etc.
Have you ever seen those billions rendered at the same time & place? 😁 There is no need to render NPCs you can’t see…
