About Lithium
Lithium is a performance-focused mod that optimizes Minecraft's core systems like physics, mob AI, and block ticking without modifying vanilla mechanics. It works on both client and server sides, with optional installation for either side. No dependencies or additional setup required, making it easy to integrate into any modpack.
For multiplayer servers, Lithium significantly improves tick rates, allowing hardware to handle more entities, chunks, and players. Single-player users benefit from smoother performance as the mod optimizes the internal game server, freeing up CPU resources for better frame rates and responsiveness.
Its strict adherence to vanilla behavior makes it ideal for complex modpacks and competitive environments like speedrunning. The mod is officially permitted in Minecraft speedrunning due to its zero-alteration approach, ensuring consistent performance across all scenarios.
Installation is simple with Fabric Loader, and no new worlds are needed. The mod's configuration system allows granular control over its patches, enabling users to disable features if needed while maintaining optimal performance.
