Insights on determinism
summary
Claims that true determinism is practical: a server-coordinated rollback architecture replaces lockstep, uses tick-by-tick input exchange at 60 Hz with simple heuristics (20-tick prediction) and deep-copy state snapshots. Experiments show naive serialization takes ~3 s, manual deep copy ~100 ms, struct-array copy ~5 ms and a native 1 millisecond memcopy is feasible. Requires fixed-point math, deterministic physics/pathfinding, and memory-aligned state; product example is Photon Quantum built on a lockstep's 30-year legacy rethought for low latency.
