If you play Minecraft on a slow computer and you want to make it run better read this tutorial! First of all lower all of your settings in Minecraft to lowest or until you get 40 or lower FPS. If you cant get near 40 FPS install the Optifine mod for Minecraft 1.3.2 (or the newest version of Minecraft). Optifine makes the game run better and gives you a lot more settings in the video settings menu. Some of the settings that it gives you are performance settings and one of the new features is that it lets you access your texture pack folder from the video settings menu.

I hope this helps with lag problems on your Minecraft!
