How to install Optifine:

This guide will show you how to install Optifine.

Optifine is a Minecraft optimization mod that allowed Minecraft to run faster and look better with support for HD textures and a lot more configuration options. Optifine can be installed using the stand-alone version or the mod version. In this guide, I'll be using the stand-alone version.
