Some implementations relate to methods, systems, and computer readable media to manage object states in a distributed multiuser environment, such as a multiplayer game environment. A client device receives an authoritative update from a designated authority node specifying a state of at least one object for a given frame.

If a discrepancy exists, the client rolls back the local state to a time corresponding to the authoritative update and applies the update to obtain an updated object state. A subsequent object state is predicted based on the updated object state and used to update a game state maintained at the client. Visual discrepancies between a last shown position and the updated game state are reconciled before rendering the object for the next frame.
