Glacier's Optimal Optimization
The author built this one for Minecraft 1.19 on Fabric. On other versions it may install and then do nothing.
Better FPS, OptiFine recreated, etc...
---------------------------------------
Optimal Optimization is a Fabric mod that focuses on performance and graphics optimizations. If you run Minecraft on 30 fps, this mod will 100% help! And, not just that, this mod recreates most of the features in OptiFine. It's designed for multiplayer and singleplayer and will make sure any world you play on is much better! This modpack is based on Fabulously Optimized by robotkoer, the modpack link is below. I hope you enjoy this fantastic modpack!
