TCP retransmission delay (Head-of-Line blocking) makes it unsuitable for real-time game physics. UDP with custom reliability headers is standard.

Client-side prediction runs movement immediately on input, while server reconciliation smooths corrections if packets disagree.

Lag compensation rewinds entity hitboxes to the past timestamp when the client fired the shot.
