About this project
What does Dynamic View and Simulation Distances add?

A lightweight server utility mod to help balancing lag(tps) and chunk view and simulation distance.
The mod balances view and simulation distance around a long-time average tps which fits the servers performance, allowing optimal view and simulation distance for each player count.
For example during low player counts when the server has a lot of performance room the distances increase and during prime time when the server starts lagging behind the distances get decreased.

- Min and Max Chunk view distance
- Min and Max Simulation distance
- Average tick time(TPS) to balance around
- Update frequency
This mod is only required on the server.
Average tick time config details:
The average tick time in the config allows you to determine the tps at which the distances get balanced around.
Tick time = <50 ms = 20 TPS, Tick time = 100 -> 10 TPS, tick time = 200 -> 5 TPS.
Version 1.18 Note: Vanilla changed behaviour of view distance changes, now they trigger a chunk reload on client-side. To avoid these I recommend using https://www.curseforge.com/minecraft/mc-mods/farsight alongside this.
No known incompatibilities.
