OptiFabric

OptiFabric is a mod that adds OptiFine compatibility to a Fabric modded environment.

OptiFabric is supported from the 1.14 OptiFine previews builds (while accessible on archive.org the download links are not archived only the website) to current versions OptiFine supports. OptiFabric is not available for 1.14.1, 1.15 and 1.15.1 as no OptiFine builds exist for them.

Installation

 * 1) Set up a Fabric modded environment; choose a launcher to use and install Fabric.
 * 2) Download OptiFine from its official site.
 * 3) Download the OptiFabric mod from Curseforge.
 * 4) When the environment is ready (for example, a large modpack or a small test pack), add OptiFine and OptiFabric to the mods folder (extracting OptiFine is not necessary).
 * 5) Launch the game with the Fabric profile; OptiFabric is installed correctly if there are additional Video Settings options. It is visible on the title screen above the Fabric loaded version and listed if the user has the Mod Menu installed (optional).



Trivia
A separated OptiFabric version (a 1.8.9 test build) is available for Legacy Fabric.
