Description

it isnt optifine btw

It's just like Optifine!

This is a modpack designed to be very close to the Optifine experience for users struggling to move pass from Optifine.

Features

  • Zoom (and how it feels!)
  • Fast grass settings
  • Optifine Smart Leaves
  • Control over what animations run
  • Optifine specific features that relate to Optifine texturepacks
  • Shader support
  • Optifine donator capes (other types of cape services too)
  • etc.

Differences?

  • Better performance than Optifine Thats pretty much it

Beta = minimal mods temporarily removed until updated to modpack version (QOL mods, not-significant performance mods)
Alpha = important performance and QOL mods removed until updated to modpack version

Donate to the authors that made the mods in the modpack over me!
