After installing Fabric for 1.16.X, you will need to place the OptiFabric mod jar as well as the latest OptiFine jar from the official OptiFine website into your mods folder. All the 1.16.5 OptiFabric versions are backwards compatible all the way to 1.16.1 so there is no need to use older versions. Is the 1.15.2 version of Optifine available from a reliable source? SOLVED: I found a video that instructs to click on 'Preview Versions' on the optifine.net download page and the 1.15.2 version is listed there, apparently usable but not completely finished. Sorry for asking the question! I would delete it, but can't figure out how.
OptiFabric
OptiFabric a mod that can be used to run OptiFine on the Fabric Mod Loader. It does this by taking the official OptiFine mod and making it compatible with the Fabric Mod Loader at runtime.
This project does not contain OptiFine, you must download it separately! Bluestacks 4.90 bstweaker.
Capture one mac os catalina. This project is not directly related to nor supported by either Fabric or OptiFine.
If you are using OptiFine purely to improve performance, have a zoom button, or have dynamic lighting, there are other mods which implement these features individually with more reliable compatibility.
