The estimated reading time for this post is 236 seconds
Since Minecraft is still in Beta, many parts of the game aren’t properly optimized yet and uses more resources than it should. There are many ways to reduce the lag. Chunk updates and saves uses a lot of CPU and GPU power, and altering it using mods can significantly speed up the game, as well as updating Java.
Don’t worry, these are not considered Minecraft cheats or hacks in any way, so they will not impact you during the online multiplayer portion of the game. This article will list some of the easy steps you can take to increase the frame-rate. If that doesn’t work well though, you may want to install some advanced mods listed later in this article.
Here’s a list of great ways to speed up your game, in no particular order:
Change the graphics settings:
If you’re lagging while your render distance is set to “Far” and “Fancy” graphics, chances that lowering them will give you a much more playable framerate. Enabling “Advanced OpenGL” also helps for some computers.
Lowering the resolution of the Window can also help; try to avoid maximizing the game widow.
Also, it might help to turn the FOV setting as of Beta 1.9 as low as possible. It reduces the amount of polygons the graphics card has to render since your field of view is lower.
Minecraft is coded in the Java programming language, updating it will impact your in-game performance. If you’re one of the few who is still running an outdated version of Java, update now! The updates often contains optimizations to speed up your game. If you’re feeling adventurous, you can get the unreleased Java 7.
Gamebooster is a free Windows utility that aims to close some resource intensive services and tasks to help you speed up your game performance. It can help you speed up the game if you are running a lot of programs at once. More information over here.
