NoTick

NoTick is a performance mod built for large modded servers.

It cuts background lag by stopping distant entities from ticking when no players are close enough for that ticking to matter. Instead of wasting server time simulating mobs, items, and other entities in far-away unloaded gameplay spaces, NoTick keeps that budget available for the parts of the world players are actually using.

The goal is simple: lower entity overhead, protect important areas, and give server admins real control.

What It Does

NoTick reduces unnecessary entity ticking in distant areas while keeping important gameplay safer through built-in protections.

By default, the mod is designed around practical multiplayer use:

players always keep normal behavior
important entity types can be whitelisted
claimed areas can stay fully active
recently used/base-like chunks can stay protected
raids and other sensitive cases can be handled separately

This makes NoTick useful for real servers, not just synthetic benchmarks.

Why Use It

Improves performance in high-entity worlds
Reduces background simulation cost in areas nobody is using
Helps large modpacks stay smoother under load
Protects important chunks through claims and activity safeguards
Gives admins direct visibility and control with built-in commands
Works without requiring extra dependency mods

Features

Distance-based entity tick optimization

Admin Commands

All commands require operator/admin permissions.

/notick Quick status view for current optimization settings
/notick status Detailed optimization and integration status
/notick here Local chunk diagnostics for your current position
/notick reload Reload the config from disk without restarting the server
/notick help Show all available commands

Best Use Cases

NoTick is especially useful for:

large modded survival servers
busy SMPs with lots of bases and farms
kitchensink modpacks with heavy passive entity load
servers where distant mob and item ticking creates constant background cost

If your server struggles because too much of the world is simulating at once, NoTick is aimed directly at that problem.

Compatibility

NoTick works on its own, but it gets even better with claim mods.

If FTB Chunks or OPAC is installed, claimed chunks can be treated as protected areas so farms, automation zones, and bases are less likely to be affected by distance-based optimization.

This fork is maintained with modpack compatibility in mind and removes the older hard dependency requirements.

Important Note

NoTick is intentionally performance-focused.

If you rely on far-away, unclaimed farms or contraptions running continuously, you should protect those areas with chunk claims, active chunk safeguards, or config whitelists.
