Rubidium++

🚀 Rubidium++ (Forge Legacy Compatibility Pack)

Rubidium++ is a specialized, lightweight modpack built for Minecraft 1.20.1 (Forge). First and foremost, this pack is designed for maximum compatibility with legacy mods that break on newer optimization engines, ensuring your old-school modded setups run flawlessly.

While its primary goal is keeping classic mods stable, it also acts as a performance booster that stabilizes frame times and reduces memory usage without altering the vanilla experience.

⚠️ Important Limitations & Technical Notes

Before installing, please keep the following critical points in mind:

• Outdated Engine: This pack is built on Rubidium, an older engine. While it works great for legacy environments, it does not feature modern graphics pipeline rewrites found in newer software.
• Newer Mod Incompatibility: Due to the legacy nature of Rubidium, this pack is not compatible with many modern, newly released mods that strictly require Embeddium or updated rendering APIs.
• Use Case: Only use this pack if you are running a specific set of older Forge mods that refuse to work on newer optimization setups.

✨ Features

• Legacy Mod Compatibility: Specially tuned to keep older, classic Forge mods working perfectly together without crashes or rendering glitches.
• Stable Performance: Powered by Rubidium to guarantee solid frames and stable frame times on older rendering pipelines.
• Shader Support: Full shader compatibility out of the box with classic Forge setups thanks to Oculus.
• Memory Optimization: Significantly reduces RAM allocation and garbage collector spikes using FerriteCore and Radium.
• Resource Preservation: Smart leaf and entity culling combined with dynamic FPS management to save hardware resources.
