Context#

V5 open-world multiplayer needs replication that can scale across high-density urban spaces, frontier posse play, capital-ship arenas, and co-op ships without replicating the whole world to every client.

Decision#

V5 uses Iris NetDriver v2 as the replication default for open-world and networked runtime modules. Cell-specific AOI and relevancy policies sit on top of Iris.

Consequences#

  • Netcode modules target Iris replication APIs.
  • Performance tests must include replication budget coverage.
  • Legacy replication paths require explicit justification.
