About this Mod
This mod re-adds the pre-1.3 smooth mob movement to singleplayer, without any latency. Also reintroduces client-side mob movement.
A video that I have posted on YouTube explains this problem here:
This mod changes the default mob tickrate from 3 to 1, and reimplements shared mob movement from both the client and server which was initially removed in 1.8. It can have glitches, though.
Known bugs:
- Horses will continue to move clientside after riding.
- Happy Ghasts cannot be controlled.

Server lagging with No Mob Latency – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if No Mob Latency consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
