✨ Lumin — Optimization Modpack

See more. Do more. Lag less.

Lumin is a client-side only optimization modpack for Minecraft Java Edition 26.2. Built on Fabric, it delivers a massive FPS boost, smoother gameplay, and reduced RAM usage — without changing vanilla gameplay or getting you banned from servers.

Works on every server. No server-side installation required. Hypixel, vanilla, Paper, Spigot — all compatible.

🚀 What Lumin Does

Category	What's Optimized
GPU / FPS	Complete rendering pipeline rewrite, entity & face culling, draw call batching
CPU / Logic	Mob AI, physics, chunk loading, lighting engine rewrite
RAM	Block state deduplication, dynamic model loading, memory leak patches
Network	Packet compression and pipeline reordering
Background	Near-zero CPU/GPU when minimized or AFK

📊 Performance at a Glance

2–3× the FPS of OptiFine on the same hardware
50%+ reduction in tick times (Lithium)
500 MB – 1 GB+ RAM savings in vanilla (FerriteCore)
~90% CPU/GPU reduction when alt-tabbed (Dynamic FPS)
No GC stutter — optimized via Aikar's Flags

🖥️ Real-World Benchmark

Tested on the developer's machine — mid-range laptop hardware, 4 GB RAM allocated to Minecraft.

System: Intel Core i5-11400H · NVIDIA GeForce RTX 3050 Mobile (4 GB VRAM) · 16 GB RAM

Configuration	Render Distance	FPS
No shaders (VSync OFF)	64 chunks	300+ FPS ✅
No shaders (VSync ON, 144Hz)	64 chunks	144 FPS (capped)
Complementary Reimagined (default)	64 chunks	60 – 70 FPS
Complementary Reimagined (optimized settings)	24 chunks	~85 – 95 FPS
Photon Shaders (medium)	24 chunks	~100 – 115 FPS
BSL Shaders (medium)	24 chunks	~100 – 120 FPS

💡 Shader tip: If you use Complementary Reimagined, reduce Shadow Distance to 64, set Volumetric Clouds to Fast, and turn off Ambient Occlusion for a ~20 FPS boost with minimal visual difference.

💡 Render distance tip: The pack includes Bobby — it caches chunks so lowering your render distance while using shaders won't leave the world looking empty on servers.
