Problem: When attacking with the non-authoritative player, there is a noticeable lag between local execution and server execution. I see about 100 ms with state interpolation and 40 ms without state interpolation.

I’m trying to confirm whether this is a normal amount of latency for two builds on the same machine. From what I’ve read, I think that most of this delay comes from the tick-based replicate/reconcile pipeline (tick processing latency) rather than the network.

Is ~40–100 ms of delay typical for same-machine, non-authoritative clients?

Definitely not.

Alright noted, thank you! I will do some research on common causes for latency.

west trout Definitely not.

Out of curiosity is there an acceptable amount latency? How far behind should the server be compared to the non-authoritative client's attack? Close to 0ms?

I would assume on the same machine it would be somewhere from 1ms to 5ms.

5 at max

If you're that much over using some sort of rollback/reconciliation, you're overloading it and/or it's flawed to begin with

Hard to say without any details
