OptiFlow is a lightweight, modern optimization mod designed to significantly boost your FPS and reduce stuttering in Minecraft. Whether you are playing on a low-end laptop or running a massive 300+ modpack, this mod re-engineers Minecraft’s rendering engine and memory management to deliver a buttery-smooth gaming experience.
Key Features
Massive FPS Boost: Optimizes chunks rendering and reduces CPU bottlenecks to maximize your frame rates.
Stutter & Lag Spike Reduction: Rewrites memory allocation to drastically reduce Garbage Collection (GC) pauses and annoying micro-stutters.
Fast Chunk Loading: Multi-threaded chunk loading ensures world generation and loading screens are faster than ever.
Server-Side Optimization: Reduces MSPT (Milliseconds Per Tick) on servers, allowing more players to explore without affecting TPS.
Fully Compatible: Built from the ground up to work seamlessly alongside other popular performance mods (like Sodium, Lithium, or Iris).
Technical Details
OptiFlow achieves high-performance gains by implementing modern algorithms and fixing vanilla Minecraft's unoptimized code paths:
Entity Culling: Stops rendering entities (mobs, items) that are not visible to the player.
Light Engine Rewrite: Optimizes the math behind Minecraft's lighting updates to prevent lag when breaking blocks.
Data Structure Optimization: Replaces heavy Java collections with fast, memory-efficient alternatives.
