🧠 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
