I have a HP Compaq NX6325 and whenever I play Minecraft it lags a lot. What could I do to make it run better on my computer?

Please do not post duplicate questions and please be more specific with your question, it's very vague.

Minecraft is horrid with the way it was coded and lags all the time, even on great computers.

Here's a screenshot of my settings (I get about 60 FPS)

You can also download a mod called "Optifine" which auto-tweaks the Minecraft java file and makes it more optimized for play on slow/old computers.

yep, the main problem is that is is java based which is very inefficient. It is also quick to lag if you are not using a 64 bit OS with the 64 bit java installed (by default the site will give you to 32 bit version, and you must manually download the 64 bit version (uninstall the 32 bit version first)

by default java will allocate a max of 1GB of RAM unless you specify more, but it is generally hard to allocate more due to the way it allocates memory, the java vm was only programmed to use contiguous memory, so you could have 50000000TB of RAM and if you have data spread out in such a way that there is only 500MB of contiguous memory, then java will only be able to allocate 500MB, even if you 1TB of free memory overall.

If you are not using the 64 bit java then do this now, http://www.java.com/en/download/manual.jsp uninstall the 32 bit java and install the 64 bit. This will allow for java to see your full address space thus increasing the chance of being able too find a large chunk of memory, it also performs much better overall.

Hopefully they will release a native windows version that uses direct x or opengl.

I wish it was written in C++, that is the greatest language (powerful and no libraries needed like Java or .NET framework) but it would take soooooo long to rewrite, and ALL Mojang knows is Java as far as I know.

cool thing to try is to write a hello world app in java and look at how much memory is uses :). (I never knew that 5 lines of code when run could take so many MB of RAM) (depending on the java, it can take around 30+ MB of RAM)

Start the game.

  1. Press ctrl/alt/and delete to bring up the task manager.
  2. Go to processes tab.
  3. Right-click Javaw.exe.
  4. Set priority to High

Cheers!

You can find a texture pack that is simple and that could increase fps by 10-30. You can also download something called gamebooster which temporarily closes unwanted processes and boots them back up after you finish gaming.
