I found this while searching for ways to make minecraft run faster. i tried this. and i had more FPS than it said i had.

Ask me any questions if you are stuck. I know how to do this and I would be more than happy to help.

Maybe you could try this
1. Go to Control Panel
2. Find the JAVA icon, and click on it
3. Java Control Panel will open and you'll find 5 or more tabs, select Java tab
4.- Push the "View..." button for Configure Java Runtime Environment.
5 .- Here is the trick, java uses only 256 mb of memory for his own purposes, and Minecraft needs more than that.

See how much ram you have and increase java's memory usage as this:

Guru's says that you can let java use the third of your total installed memory, for me its easy as I only have 3gb of installed ram on my computer, so i'm gonna let java deal with 1024 mb of ram (1 Gig) how?

add this command in your Runtime Parameters on each entry that you have in this list.


as shown above no spaces with the minus symbol at the beginning and an "m" at the end.

in the above example, 1024 is the amount of memory that java will use, you can try 512 for small machines or 2048 for big ones

OR You could set minecraft a higher priority in task manager. just right click it in task manager and set it to realtime. if it glitches set it to highest or higher.

This is nothing to do with FPS. Changing the java heap space will mearly allow more space to use HD content and mods.

your FPS is completly dependant on your Graphics card and your Hard drive read speed (for chunk loading)

Adding extra run time memory to java with remove Running space from your operating system. You WILL crash much more often if you set it too high. Make sure its half of what you need.
