Graphene Mod (1.21.8, 1.20.1) – Maximum Performance

Graphene Mod is a powerful, open-source performance mod for Minecraft that fixes vanilla bugs and greatly improves frame rate, startup speed, and server performance. It works with almost everything in your mod folder and remains highly configurable, so you can turn features on or off as needed. Whether you run a light client or a 400-mod kitchen-sink pack.

Features:

• Performance Improvements:
  • Distant entities and tile entities far from players stop ticking to save performance
  • Protects important entities like bullets and the Ender Dragon from freezing
  • Faster client startup that shaves seconds off launch time
  • Background throttling mode lowers FPS and chunk updates when window is out of focus
  • Instantly restores full performance when you return to the game
  • Quicker world generation compatible with other chunk acceleration mods
  • Light engine improvements reduce lighting recalculations
• Rendering Improvements:
  • Leaf culling (ver 1.21.1 and below only)
  • Static chest models are batched and skipped at long range
  • Configurable chest render distance
  • Reflex feature lowers render latency for better responsiveness
• Gameplay Fixes:
  • Boats no longer break or take fall damage from any height (vanilla bug fix)
  • Ground item merger for faster performance (configurable replacement for Stxck mod)
  • Suppresses bamboo light checks
  • Language changes apply instantly without resource pack reload
  • Several memory leak patches ported from standalone mods
• Configuration:
  • Every optimization can be toggled in config/graphene.toml
  • Turn off any feature that doesn’t work for your setup
  • Some aggressive optimizations are off by default
  • Highly configurable for different playstyles and mod setups
