介绍
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 |
