Installation

If possible start with a clean minecraft.jar and check the mod compatibility section above.

A. Easy Installation

• 1) Download and start the Magic Launcher
• 2) Click Setup, click Add, select the downloaded zip file
• 3) Click OK, login and play Minecraft

B. Manual Installation

Windows/Linux Instructions:

• 1) Locate your minecraft.jar file. On Windows, it’s in %APPDATA%/.minecraft/bin
• 2) Create a backup of minecraft.jar
• 3) Open minecraft.jar in an archive editor (WinRar/7-Zip/etc)
• 4) Delete the META-INF folder.
• 5) Copy (drag and drop) the .class files from the downloaded zip file into the jar file, replacing previous files.
• 6) Run Minecraft and test!

Mac Instructions:

• 1) Locate your minecraft.jar file. On Mac, it’s in <home>/Library/Application Support/minecraft/bin
• 2) Create a backup of minecraft.jar
• 3) rename minecraft.jar to minecraft.zip and double-click it to extract the contents

Tips and tricks:

• 1. Download the latest Java 7 builds from here: https://download.java.net/jdk7/. Minecraft should run much smoother with less lag spikes. It really helps.
• 2. Set the Java process to higher priority
• 3. Set “Limit framerate” to Max FPS. The limiter is so implemented that it always decreases the FPS.
• 4. Update LWJGL from here.
• 5. Lauch Minecraft with less memory (yes, really). It needs maximum 256 MB and runs fine on all settings with the default texture pack. By default java allocates too much memory (1GB?) which may get swapped to disk and the overall performance may suffer a lot.

To start Minecraft with less memory:

• Download and start the Magic Launcher
• Click Setup
• Enter 256 in the field “Memory”
• Click OK
• Login and play

OptiFine HD A7 Ultra for Minecraft 1.4.2

(has all the features of Standard, Smooth, Multi-Core and AA, highly configurable)

The option “Video Settings -> Chunk Loading” switches between Standard, Smooth and Multi-Core chunk loading. When using “Chunk Loading: Multi-Core” make sure to Disable “Threaded Optimization” / “OpenGL Threading”  in the graphics card control panel (example). For best results disable it globally, not only for java.exe or minecraft.exe.
