Prismanium is a performance-focused renderer fork for Minecraft Forge built for large modpacks that need smoother rendering, better compatibility, and extra quality-of-life features.
It is based on the Sodium/Embeddium rendering stack and expands it with integrated dynamic lights, Oculus shader compatibility work, TACZ rendering optimizations, split-screen improvements, realtime performance overlays, and safer diagnostic tools for modpack troubleshooting.
Main Features
- Optimized chunk rendering based on the stable Sodium/Embeddium pipeline
- Integrated dynamic lights for held items, dropped items, entities, accessories, and compatible gear
- Oculus shader compatibility improvements
- TACZ rendering and attachment cache optimizations
- Realtime FPS, frame time, CPU, and GPU overlay
- Optional log issue notifier for recipes, mixins, server lag, network pressure, worldgen, and crashes
- Split-screen detection and optimizations for multiple local Minecraft instances
- Borderless window mode alongside normal fullscreen and windowed mode
- GUI/HUD performance optimizations
- Entity and block entity culling options
- Integrated server tick budget optimizations for singleplayer/LAN worlds
Prismanium is designed for modded gameplay where performance, shaders, weapons, dynamic lights, and large mod lists need to work together without sacrificing visual quality.
Compatibility Focus
Prismanium currently focuses on Forge 1.20.1 compatibility with Oculus, TACZ, ModernFix, Lithium-compatible environments, Xaero’s Minimap/World Map, JEI-heavy packs, and large CurseForge modpacks.
This project is still evolving, so feedback, logs, and compatibility reports are welcome.
