About this Mod

Fast Doll

Requires: Fabric API

In Minecraft the player model in the inventory is updated only 20 times a second (every tick), which makes the movement looks choppy / laggy.
This mod makes it render at full speed, making the movement look smooth. (Video)

When using with Mod Menu you can access a simple config screen that lets you enable and disable the mod.
Note: The mod is enabled by default.

Frequently Asked Questions

FastDoll server crashes on startup – what to do?

Server lagging with FastDoll – how to optimize performance?

Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if FastDoll 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.
