How to Install OptiFine on Minecraft Java Edition

OptiFine is one of the most widely used Minecraft optimization tools. It enhances performance, improves FPS, unlocks shader support, and adds advanced video settings that are not available in the base game.
This guide explains how to safely download and install OptiFine on Windows, macOS, and Linux, along with optional steps for Forge users and shader support.

• A stable internet connection

If Java is missing, download it from the official site: https://www.oracle.com/java/technologies/downloads/

2. Place the shader ZIP file in the following folder:
   .minecraft/shaderpacks
3. Launch Minecraft with OptiFine.
