I recently installed Minecraft on my Ubuntu 12.04 LTS computer with all the correct Java packages and LWJGL, but when I go to play it, the FPS rate drops to ~3 fps and freezes every second, making play almost impossible. My hardware specs. are:

Memory: 3.6 GiB

Processor: AMD Athlon(tm) II X2 245 Processor × 2

Graphics: GeForce 7025 / nForce 630a/integrated/SSE2

OS type: 64-bit

Disk: 242.2 GB

Java: java version "1.6.0_31"

OpenJDK Runtime Environment (IcedTea6 1.13.3) (6b31-1.13.3-1ubuntu1~

OpenJDK 64-Bit Server VM (build 23.25-b01, mixed mode)

Minecraft version: 1.7.2

OK, I hope that helps... Please reply.

EDIT: My processor frequency is 2900 MHz.

  • I get along just fine with 1gb memory, 1.6 GHz Intel atom, and on board graphics. so it is probably a software issue. Maybe you should try reinstalling Ubuntu and possibly switching to 14.04. – Sir_Yoshi Jul 20 '14 at 3:15
  • Which video driver are you using? – kraxor Jul 20 '14 at 3:27

Look on the minecraft System Requirements page

It says:

Recommended Requirements:
CPU: Intel Core i3 or AMD Athlon II (K10) 2.8 GHz
GPU: GeForce 2xx Series or AMD Radeon HD 5xxx Series (Excluding Integrated Chipsets) with OpenGL 3.3
Latest release of Java 7 from java.com

This may be why, you only have 3.8 GB of RAM. Also, how many GHz is your processor?
