Rubidium

Rubidium is an unofficial fork of CaffeineMC's "Sodium", adapted to work with Forge Mod Loader.

Features and Advantages

Rubidium includes all the functionality of classic Sodium and introduces significant performance improvements to Minecraft.

Modification implements a modern OpenGL rendering pipeline for chunk display that utilizes multiple draw operations. This reduces CPU load by approximately 90% when rendering the game world, which is particularly noticeable on computers where CPU was the main limiting factor.

Key Optimizations:

• Vertex data for displayed chunks becomes significantly more compact, reducing video memory and bandwidth requirements by almost 40%
• Nearby block updates are now distributed across multiple threads, minimizing delays during chunk rebuilding
• Inactive chunk faces (invisible or facing away from the camera) are culled early in rendering stages, eliminating unnecessary geometry
• Multiple improvements to chunk loading and block drawing accelerate the process and reduce impact on frame rate
• Substantial optimizations for vertex creation and matrix transformations speed up rendering of entities, custom blocks, and items

Additional Benefits:

• Enhanced memory management and object allocation reduces resource consumption and minimizes garbage collection-related delays
• Graphics fixes for smooth lighting provide better performance while maintaining quality
• Smooth lighting for liquids and special blocks
• Smooth biome blending for blocks and liquids significantly improves graphical quality with lower computational requirements
• Animated textures invisible in the world are not updated, accelerating texture processing
