Optim is a Fabric modpack that aims to provide maximum performance with some common quality-of-life modifications to the game. It is a highly opinionated selection of mods I intentionally handpicked to share my improved experience with the wider Minecraft community.


🌟 Features

Main Features

  • Vanilla Parity - Doesn't add any new content to the game as it aims to be compatible with all Vanilla servers.
  • Optifine Parity - Replacements for most Optifine features like Shaders, CEM, CIT, Animated & Connected Textures, Capes, Dynamic Lighting and Custom Sky Boxes.
  • Regularly Updated - Actively maintained and updated to newer Minecraft versions.
  • Optimized - Strives to provide the best possible performance while still having all the bells and whistles.

Other Features

  • Replay Mod - The best way to record and capture replays.
  • Roughly Enough Items - The go-to mod for browsing receipes.
  • Auth Me - Has your client been launched for too long? Use the authenticate button in the server list. No need to restart.
  • Improved Third Person - Minecraft's third-person mode is old and clunky, the new one allows you to turn the camera without turning your character.
  • 3D-Skin-Layers - Makes skins look fabolous by improving rendering of the 3D layer.
  • Wavey Capes - Capes now blow beautifully in the wind.

❤️ Acknowledgments

Optim was created because I grew tired of manually updating my personal selection of mods after every Minecraft update.

The following projects inspired, influenced and or helped me greatly when creating Optim:

  • mc-modpack-kit - Used to scaffold this GitHub repository.
  • Packwiz - Exceptional software making modpack maintenance and creation easy.
  • Kami Chan Optimized - Inspired a few additions like fast-up-ping and Server Pinger Fixer.
