About this Mod

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)

Frequently Asked Questions

Immersive Optimization server crashes on startup – what to do?

Most common cause: wrong fabric version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (26.1.2). You can switch loaders with one click in the panel.

Is Immersive Optimization compatible with fabric and forge and neoforge?

Immersive Optimization officially supports fabric, forge, neoforge for Minecraft 26.1.2, 1.21.11, 1.21.1. Note: Forge and Fabric mods are NOT cross-compatible – pick one loader and stick with it. The Mado dashboard automatically detects incompatible loader combinations.

Server lagging with Immersive Optimization – how to optimize performance?

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