Simply OptiFabric is a lightweight, clean, and straightforward Fabric modpack designed specifically to bring the authentic OptiFine experience into modern Minecraft 1.20.1. No clickbait, no fake Sodium setups—just pure, real OptiFabric optimization.
This pack acts as a ready-to-use foundation, containing all the essential system APIs and configuration libraries needed to run the OptiFabric bridge smoothly alongside useful vanilla+ client enhancements.

⚠️ IMPORTANT: HOW TO ACTIVATE SHADERS & VIDEO SETTINGS
----------------------------------------------------
Due to strict licensing and copyright regulations from OptiFine's creator, the official OptiFine.jar file cannot be bundled directly inside the downloaded modpack file.
To get your shaders, custom capes, and video settings menu working, please follow these 2 simple steps right after installing the pack:
1. Go to the official OptiFine website and download OptiFine 1.20.1 HD U I6.
2. Open your modpack profile via the CurseForge App, click "Open Folder", navigate into the "mods" folder, and drop the downloaded .jar file inside.
*OptiFabric is already fully embedded in this pack and will automatically bridge your manually added OptiFine jar as soon as the game launches!*
