To scale Unreal Engine multiplayer replication, you need to configure a ReplicationGraph to manage actor routing, spatialization, and relevancy rules. This allows the dedicated server to efficiently handle large numbers of replicated actors.

ReplicationGraph manages actor relevancy and connection routing by placing actors into specific graph nodes. This architecture determines which actors are visible to which connections, supporting prioritization, owner-only visibility, and dormancy workflows.

You need ReplicationGraph when your multiplayer project suffers from replication performance issues due to large actor counts or complex relevancy rules. It provides the network scalability required for dedicated servers when standard NetDriver configurations fall short.

To debug actor visibility and replication placement issues, you must inspect your ReplicationGraph configuration and validate routing strategies. This involves checking graph nodes, connection handling, and dormancy states to identify incorrect network architecture constraints.

The best way to configure NetDriver for spatialized actor replication is to integrate it with a ReplicationGraph. This setup optimizes network scalability by routing actors through spatialization nodes and applying always-relevant or owner-only replication rules.

Your Unreal multiplayer server has replication bottlenecks because standard networking lacks scalability for large actor counts. Implementing a ReplicationGraph architecture optimizes actor routing, relevancy management, and prioritization to resolve these performance issues.
