Description
Harium | General Optimization
Comprehensive Game Physics & Logic Optimization
What Is Harium
Harium is a general-purpose optimization mod (based on Radium/Lithium).
It improves game physics, mob AI, world generation, and block ticking performance without changing any vanilla mechanics.
Invisible but Essential.
You won't see Harium working, but you will feel the difference: smoother MSPT, better mob responsiveness, and fewer lag spikes.
Technical Architecture
Harium optimizes the "micro-ticks" of the game.
- Physics Engine: Optimize collision detection to reduce CPU overhead
- Mob AI: Faster pathfinding and goal selection for mobs
- Block Ticking: Efficient processing of block updates and redstone
- Vanilla Parity: Strictly compliant with vanilla behavior
Fork Information
Harium is a fork of Radium (itself a port of Lithium).
It brings the massive optimizations of the Lithium project to the Forge ecosystem.
Credits & Support
Based on Lithium by CaffeineMC.
Radium Port by Asek3.
Harium extends this legacy of optimization.
