Dimension Tickrate

This mod allows server administrators to configure independent target TPS values for different dimensions, transforming performance optimization from a global slowdown into dimension-based performance management.

Overview

The core idea of this mod is to isolate heavy server load into specific dimensions.

Server owners can create dedicated machine, industrial, or resource dimensions and encourage players to place high-load structures there, such as:

• Large automation systems
• Industrial machines
• Pipe networks
• Mob farms
• Automatic production lines
• High-frequency ticking block entities

The TPS of these dimensions can then be reduced independently, minimizing their impact on commonly used dimensions such as the Overworld, Nether, and End.

Example

/tickrate set minecraft:overworld 20
/tickrate set custom:machine_dimension 10
/tickrate set ad_astra:moon 5

This means:

• Overworld runs at vanilla speed (20 TPS)
• Machine dimension runs at 10 TPS
• Moon runs at 5 TPS

Each dimension is processed independently.

Reducing TPS in one dimension will not affect gameplay smoothness in other dimensions.

Commands

Set dimension TPS

/tickrate set

Value range: 1–20

Examples:

/tickrate set custom:machine_dimension 10
/tickrate set custom:factory_dimension 5

Get dimension TPS

/tickrate get

List all configured dimensions

/tickrate list

Reset dimension TPS

/tickrate reset

Resetting restores vanilla behavior (20 TPS).

What is affected

Lowering a dimension’s TPS affects all server-side ticking logic inside that dimension, including:

• Block ticks
• Fluid ticks
• Entity ticks
• Mob AI
• Item updates
• Modded machines
• Automation systems
• Other tick-dependent mechanics

To avoid completely freezing players in slowed dimensions, the mod preserves low-frequency player updates even when full dimension ticks are skipped.

Installation

Minecraft Version: 1.21.1
Loader: NeoForge
Installation Target: Server-side

Dedicated servers only require server installation.

For singleplayer or LAN worlds, install on the local client since Minecraft runs an integrated server.

Data Persistence

Dimension TPS settings are stored using world persistent data.

Configured TPS values are automatically preserved after server restart.

Recommended Usage

Recommended setup:

• Keep Overworld, Nether, and End at 20 TPS
• Create dedicated machine or factory dimensions
• Move heavy automation into those dimensions
• Start testing at 15 or 10 TPS
• Adjust gradually based on MSPT and player feedback

Example:

/tickrate set custom:machine_dimension 15

If needed:

/tickrate set custom:machine_dimension 10

Avoid setting extremely low TPS immediately, as machines and farms will noticeably slow down.

Notes

This mod does not increase Minecraft’s maximum TPS beyond vanilla’s 20 TPS.

It reduces server load by decreasing tick frequency in selected dimensions.

Some mods that rely on high-frequency ticking may behave differently under reduced TPS.

If issues occur, check configuration with:

/tickrate list

Then reset if necessary:

/tickrate reset
