Which do you have installed? BEFORE YOU ANSWER
open a command prompt and type or paste the following:
you are using 64 bit java IF AND ONLY IF the phrase 64-bit appears.
java version "1.6.0_21"
Java(TM) SE Runtime Environment (build 1.6.0_21-b07)
Java HotSpot(TM) 64-Bit Server VM (build 17.0-b17, mixed mode)
When I run it on my 32 bit laptop, I get instead:
java version "1.6.0_22"
Java(TM) SE Runtime Environment (build 1.6.0_22-b04)
Java HotSpot(TM) Client VM (build 17.1-b03, mixed mode, sharing)
Which version do you use for minecraft? I typically use the 64 bit version whenever possible because the RAM ceiling is higher and Minecraft has ... RAM FATNESS ISSUES. I have only very rarely had issues with the game crashing for any reason apart from something I did to it (like blowing up 12000 blocks of tnt)
That being said, you might see a performance increase if you download minecraft.jar from the site and run it with:
And thanks for this topic, you made me go check my Java install, and I found out that I had the wrong version.
I just checked Minecraft, my FPS seems to have close to doubled, from 80 ish FPS, to 13-140 FPS. Will need further testing, but I think that should solve quite a bit of the random lag issue I was having.
+10 internets to you. your internets were revoked because you tried to pull a sneaky.
you should also edit your post, the entire point of my first post is that 64bit windows != 64bit java, which is kind of what the post looks like.
you sure you didn't install it after you noticed that you were wrong? an hour is an awful long time to run 1 line of code... IIRC, the installation itself goes smoothly, but the download is about as smooth as a bucket of gravel. WITH SPIKES.

It looks like he installed the 64-bit java in response to a different problem shortly before this thread, not in response to it.
@Haxivius: I think you're seeing a lot of sudden responses to your post because people are interpreting "Since I've got a 64bit OS, I'm using 64bit Java." as meaning "64-bit Java came with my 64-bit OS", which is of course the opposite of what the OP is saying. What I'm guessing you're actually saying is "Because I run a 64-bit OS, I took pains to make sure I'm running a 64-bit Java", which is what the OP is advocating.
This is one of those fun threads where everyone is actually agreeing without knowing it :smile.gif:

This forum ticked me off so much I went to random.org and set my password to something I'll never be able to remember, then switched my password reset to a throwaway.
i would have sworn i had 64 bit java as well until i read you had to go to the java site using a 64 bit browser for it to let you download java 64 bit. sure enough i only had the 32 bit. i went back using 64 bit internet explorer and it took me right to the 64 bit download. actually a noticeable improvement. kinda makes sense. oh, and if you do this you should remove 32 bit java manually or you will have both 32 and 64 and minecraft will use the 32. thats what mine did anyway.
