Instructions
Start "Minecraft." Enter your username and password, and click "Login."
Click the "Options" button in the main menu. Click "Video Settings" to open the video configuration controls.
Click the "Graphics" button to switch it from "Fancy" to "Fast." Click the "Performance" button until it reads "Power Saver." These settings reduce the framerate of the graphics in "Minecraft."
Click the "Render Distance" button until it says "Tiny." This tells "Minecraft" to only display graphics that are very close to your character.
Click the "Smooth Lighting" button to set it to "Off." This reduces the complexity of the in-game lighting.
Click "Done" to apply the new, lower-quality graphics settings.
