Description

MaximizeMTRMod

A client-side performance mod for Minecraft Transit Railway (MTR 4.x)

<kbd>[English](README.md)</kbd> <kbd>[简体中文](README_CN.md)</kbd>

Reduces rendering load and data sync overhead for MTR 4 through distance-based culling, sync throttling, and chunk-loading smoothing. Drop-in client-side mod — no server-side installation required.

Features

Feature How it works Default
Vehicle Culling Skip rendering trains beyond a configurable distance 128 blocks
Block Entity Culling Cull PSDs, signals, PIDS, station names at distance 56 blocks
Rail Culling Skip rail rendering when far; always show when holding MTR tools 128 blocks
Lift Culling Skip lift rendering beyond range via Accessor-read coordinates 80 blocks
Sync Throttling Reduce HTTP poll rate when no transit entities are nearby 40 blk full / 12 tick throttle
Chunk-Load Smoothing Detect trains heading into unloaded chunks, tighten render distance temporarily 200ms check interval
Frame Interlacing Alternate render distance every N frames, distant trains render less often Every 2 frames
