OptiFabric Mod is a mod that can be used to run OptiFine on Fabric. It does this by taking the official OptiFine mod and making it compatible with the Fabric Modloader at runtime, which allows you to play with mods and shaders, or textures that require OptiFine.
Features:
- Reduces lag and improves game performance by optimizing various aspects like block entity rendering, game physics, mob AI, and block ticking.
- Automatically reduces the speed at which Minecraft renders when it’s not focused, helping to maintain a smooth frame rate.
- Supports custom and random entity textures, including emissive/glowing textures and blinking mobs.
- Allows for quick changes to the game’s language.
- Helps to lower the amount of RAM used by the game.
- Optimizes the Minecraft network stack for better multiplayer performance.
Note:
- This project does not contain Optifine, you must download it separately.
- This project is not related or supported by either Fabric or Optifine.
