🕒 LongerPlaying The "Zero-Reset" Performance Utility.
LongerPlaying is a lightweight, engine-level optimization mod for Fabric 1.21.1 – 1.21.11. It is specifically designed to solve "Session Decay"—the gradual accumulation of lag and stuttering that occurs when Minecraft is left running for several hours.
While most performance mods focus on raw FPS, LongerPlaying focuses on stability over time, allowing you to keep your client open for 12+ hours without the need for a restart.
🚀 Key Features Silent Cache Purging: Unlike other tools, LongerPlaying clears out old textures and model data in the background. No loading screens, no "Mojang logo" interruptions—just a smooth experience.
Native Buffer De-allocation: Explicitly clears Vertex Buffers from your system and GPU memory as you move between chunks, preventing the "invisible" RAM bloat that slows down your PC.
Dimension-Hop Flush: Automatically performs a deep memory sweep when switching dimensions (e.g., entering the Nether), ensuring the game feels as fresh as when you first launched it.
Ghost Entity Cleanup: Scans and removes tracking data for entities that have already been unloaded, freeing up CPU cycles for your immediate surroundings.
📈 Why Use LongerPlaying? Vanilla Minecraft is prone to "Memory Fragmentation." Over many hours of play, your RAM becomes disorganized, forcing the Java Garbage Collector to work harder, which causes micro-stutters. LongerPlaying acts as a silent janitor, organizing and clearing memory before it becomes a problem.
🛠️ Compatibility Optimized for Sodium: Works perfectly alongside Sodium, Lithium, and Iris.
Client-Side: This mod is 100% client-side. You can use it on any server to improve your own personal performance.
Zero-Config: Works out of the box with "Safe-Default" settings.
