About this Mod
🧠 ChunkSense
Smart chunk loading + memory watchdog for Minecraft Forge 1.20.1
ChunkSense does two things that no other mod does:
1. Smart Chunk Prioritizer — chunks are loaded not in a circle, but along the vector of view and movement. Looking north — northern chunks load first. Running east — chunks ahead pre-load.
2. Memory Watchdog — monitors RAM in real time. If there's not enough memory, it automatically unloads distant chunks, reduces render distance, and clears the cache. The HUD overlay shows real-time status.
⚡ Features
- 🎯 View-direction priority — Chunks in camera direction load first
- 🏃 Movement prediction — Pre-loads chunks along player velocity vector
- 📊 RAM monitoring — Tracks memory usage every second
- 🚨 Auto-unload — Unloads far chunks when memory is low
- 🔭 Dynamic render distance — Auto-adjusts render distance based on RAM
- 📟 HUD overlay — Shows RAM %, FPS, render distance on screen
- ⚙️ Fully configurable — All thresholds and features toggleable

ChunkSense server crashes on startup – what to do?
Most common cause: wrong forge version or insufficient RAM. Check the server log (latest.log) for "OutOfMemoryError" or "Mixin" errors. With Mado Hosting: ensure at least 3 GB RAM is allocated and the loader matches the mod version (1.20.2). You can switch loaders with one click in the panel.
Is ChunkSense compatible with forge?
ChunkSense officially supports forge for Minecraft 1.20.2, 1.20.1. The Mado dashboard automatically detects incompatible loader combinations.
Server lagging with ChunkSense – how to optimize performance?
Recommended RAM: 4 GB (per 8 players). Use /spark profiler to check if ChunkSense consumes the most tick time. Common fixes: reduce server view-distance to 8-10, install "performant" or "starlight" as supplementary mods on Forge. With Mado Hosting, your server runs on NVMe SSDs with dedicated CPU cores for minimal latency.
