Jellysquid's Optimised Shaders
Jellysquid's Optimised Shaders is a precision-engineered modpack designed to deliver the ultimate balance of high-end visual fidelity and peak hardware performance. By combining the legendary optimization suite from CaffeineMC with modern shader support, this pack ensures your game looks stunning without the usual performance tax.
The JellySquid Performance Suite
At the heart of this pack is the full engine overhaul developed by JellySquid, designed to maximize frame rates and eliminate stuttering:
Sodium: The gold standard in rendering engine replacements, providing massive boosts to FPS.
Lithium: Optimizes game physics, AI, and block ticking to keep your world running smoothly.
Phosphor: A high-performance lighting engine that fixes "lighting lag" and speeds up world generation.
Hydrogen: Reduces memory overhead, allowing the game to run efficiently even on systems with less RAM.
Extra Mods
To complete the experience, we’ve added essential tools for customization and stability:
Iris Shaders: The primary engine for this pack. It allows you to run your favorite shader packs with native Sodium compatibility for unparalleled speed.
Mod Menu: A clean, easy-to-use screen to manage your mods and tweak settings on the fly.
Crash Assistance: Integrated diagnostic tools that help identify and solve technical issues, ensuring your play sessions stay uninterrupted.
