Description

Immersive Optimization

Modrinth CurseForge Discord Github Translate via Crowdin

An entity tick scheduler to massively reduce lag (~200% speedup) and resource requirements of entities.

Unlike similar projects, this mod will not disable ticks all together, allowing farms or distant entities to still function.

Works great together with Entity Culling.

Discord

While tested thoroughly, I expect some rough edges. Please report any issues on GitHub or Discord.

Features

  • Gradually slows down tick rate of entities and block entities
  • Distributes updates over multiple ticks to flatten lag spikes
  • Dynamically adjusts tick rate based on server load
  • Configuration commands (/io ...)

Tested Mod-Packs

Exact values change based on situations, but I observed:

  • 150% higher performance in Cobblemon 1.20.1 Fabric
  • 330% higher performance on a private 700 mods pack (Gallery example)
