⚙️ OptiCore — Fabric Optimization Pack

A lightweight optimization pack for Minecraft Fabric — delivering maximum performance without compromising vanilla features or gameplay. This is an optimization pack built for players who want the best of both worlds: significant performance gains with zero compromise on the vanilla experience. Whether you're playing on a low-end machine, chasing higher FPS, or running a multiplayer server — OptiCore is built for you.

Features:

  • Performance & FPS Boost — Significantly improved performance and higher FPS, thanks to a carefully selected set of optimization mods.
  • Shader Support — Enhance your game's visuals with beautiful shaders, included and ready to use out of the box.
  • Dynamic Lighting — Light up your surroundings by holding torches and other light sources, without placing them down.
  • Quality of Life — A collection of small but impactful improvements: better chat history, faster quitting, improved advancement screen, shulker box previews, zoom and more.
  • Fully Vanilla Compatible — No new items, blocks, or mechanics. Play on any vanilla server without issues. Performance Monitoring — Built-in profiling tools to track and diagnose performance in real time.
  • OptiFine Parity — Enjoy features you know from OptiFine — capes, custom GUIs, custom skyboxes, connected textures, and more — all without the performance cost.
