How to install Optifine
This guide will show you how to install Optifine.
The obvious thing to try first is installing 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 will be using the stand-alone version.
First, you will have to download Optifine from the website:
Choose the version that you would like to play in. If it is a newer version that has not been released yet, try to find it in "Preview versions".
Make sure you have 64-bit Java installed. If you play Minecraft, you probably have it already installed, but updating cannot hurt.
After downloading, close Minecraft and the launcher if they are open.
Install Java by double-clicking it, just click next until Java has finished installing.
Now you may install Optifine, by double-clicking the file. After a couple of seconds, it should show a window. Then press install. It can take several minutes to install, but when it is done press "OK".
If it installed correctly, you can delete the files you have downloaded. After that, just launch the Minecraft launcher and the Optifine release should be set as a preset profile. Then start the game.
If you see "(Modded)" next to the game version, then congragulations! You have now installed Optifine! But to get even more FPS I recommend changing some settings, or you could follow my other guide.
