Latency Compensation Taxonomy

Speculative Execution

Speculative Execution computes the game world state based on possible player input before it has actually happened and adopts this pre-computed state if/when the input is provided. This enables the local game client to respond to player input immediately, matching the current game world to the pre-computed world, without waiting for the round-trip time to the server.
