OptiFine is an essential mod for any Minecraft player wanting to use shaders or enhance their graphics performance. Here's how to get it and use it.

Then, select “Open With” and “Java”. if you don’t have Java or the Java file doesn’t work, you will need to download Java 21. This is required for Minecraft 1.21.4 mods like OptiFine.

Minecraft 1.21.8 Optifine has just received the latest support build, allowing players to use shaders and graphical customizations alongside the content in the Chase the Skies drop.
