Immersive Optimization
ModrinthA lightweight entity-tick-scheduler for doubling your TPS.
Immersive Optimization
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.

- Gradually slows down tick rate of entities and block entities
- Distributes updates over multiple ticks to flatten lag spikes

/io ...)
Tested Mod-Packs
Exact values change based on situations, but I observed:

- 330% higher performance on a private 700 mods pack (Gallery example)
