Our Minecraft Launcher is able to be updated so it is easy to keep up to date. To install, click the button below and open the application that is downloaded. To fix the lag on Minecraft set the Render Distance on tiny, put the brightness on bright, turn the clouds off, put the graphics on fast, turn the performance on Max FPS (Frames per Second), and set the particles on minimal. If it still lags, your computer can't handle Minecraft. Java is very demanding. To get gaming computers, visit Alienware's website, Alienware.com. Know that this launcher is cracked so you cannot play on all multiplayer servers. However, you can play on LAN (Local Area Network) games, where one person opens the world to LAN (Local Area Network). You can play on some serves, but they must be cracked. If you want to play on all servers, you must buy an account. Sorry for the inconvenience. Thanks.
