Hydrogen
Project Status January 23rd, 2022
This repository has been archived due to lack of time and resources to maintain the project. No further updates will be released, and we won't be able to provide assistance with its usage.
If you're looking for a replacement, we recommend checking out FerriteCore, as it typically provides more significant memory usage improvements in modded scenarios and is available for the latest version of Minecraft.
Memory usage before and after installing Hydrogen in the popular All of Fabric 3 modpack
Hydrogen is a free and open-source mod designed to reduce the game's RAM requirements by implementing more efficient data structures and algorithms. While primarily intended for heavily modded gaming environments, even in light modifications or vanilla gameplay you can notice small improvements.
The mod works on both client and server, without requiring installation on both sides simultaneously. However, currently the benefits of running Hydrogen on the server are quite minimal.
Key Features
- Optimized data structures for block states and properties, significantly reducing memory consumption when using mods that add numerous complex blocks
- Elimination of duplicate block model geometry, saving client memory when working with multi-part block models
- Memory leak fixes in chunk loading code, preventing NBT data from disk from remaining in RAM after chunk loading
- Simplification and optimization of block model predicates to reduce unnecessary chaining
