OptiFabric Mod

OptiFabric is a simple mod that allows you to run OptiFine on the Fabric mod loader. This mod takes OptiFine and makes it compatible with Fabric at runtime. Note that OptiFine does not come bundles with this mod, so you'll have to download it separately from the official website. Add both the OptiFabric mod and your preferred OptiFine version to .minecraft/mods folder and you will be able to access the wide range of tweaks and setting that OptIFine offers, on Fabric.
