# 🚀 High-Performance Voxel Engine (Minecraft-Like)

A **high-performance, fully multi-threaded voxel engine** that supports **massive render distances without FPS drops**. Designed for **real-time procedural terrain generation, fast world streaming, and ultra-efficient memory management.**  

## 🌟 Features

- **128 Render Distance at Stable FPS**  

  - Tested on an **RTX 3070 8GB** at **165Hz VSync ON** with **no FPS drops**.  

- **Lightning-Fast Disk Reads/Writes**  

  - **Ultra-efficient region format** keeps file sizes small while maintaining **instant chunk streaming**.  

- **Full World Streaming**  

  - Loads and unloads chunks dynamically, supporting **seamless infinite terrain exploration**.  

- **Procedural Terrain, Caves, and Trees**  

  - **Fully procedural world generation** with **realistic cave systems, biomes, and natural structures**.  

- **Multi-Threaded World Generation & Updates**  

  - **Dedicated IO threads** ensure that the **main thread only handles GPU uploads & coordination**, keeping performance ultra-smooth.  

- **Render Regions for Optimized Draw Calls**  

  - **Batched rendering** reduces CPU overhead, allowing for **massive draw distances with minimal performance impact**.  

- **Zero Garbage Collection Pressure**  

  - Uses **manual memory management (`unsafe` pointers for voxel data)** to completely **eliminate GC pauses**, ensuring **stable frame times** even under heavy load.  

## 🛠️ Technical Details

- **Written in C# with Ahead-of-Time (AOT) Compilation** for near-native performance.  

- **Uses RLE + LZ4 OPT 10 compression** to **minimize storage requirements** while keeping chunk loading near-instant.  

- **Full camera-relative rendering**, preventing **floating-point precision issues at extreme world distances**.
