ChunkOptMod is a Forge mod that makes Minecraft run smoother when loading new terrain. Instead of doing all chunk generation and decoration at once, it spreads the work across multiple threads and places heavy tasks like trees and structures gradually.
This means less lag when you explore, fly fast, or run a busy server. The mod also watches your server’s TPS (ticks per second) and automatically adjusts how much work it does each tick to keep performance stable.
