I'm on Ubuntu 11.10, and I am having trouble with Runescape, an in-browser Java game.

My fps used to be 40-50 when I would play on Windows, but now, on Ubuntu I'm at 4-5 fps. Any ideas on how I can fix this?

I use Chromium, and have installed Java 1.7.0_03

browser and java version?... – Uri Herrera Mar 8 '12 at 22:29
I'm in Chromium, Java 1.7.0_03. If I run it in the Unix Client that is based off of the Windows client, that uses Java 1.6. It too runs at the same low fps. – Ryan McClure Mar 8 '12 at 22:30

I've browsed this forum a few times (that's where I found the client, haha). What exactly should I be looking for? – Ryan McClure Mar 8 '12 at 22:37

the issue with java7/openjdk7 is that they have linking issues with their own libraries so adding them into LD_LIBRARY_PATH should get you out of safemode :)

here is an example command using firefox and openjdk7

32bit: LD_LIBRARY_PATH=/usr/lib/jvm/java-7-openjdk-i386/jre/lib/i386 firefox

64bit: LD_LIBRARY_PATH=/usr/lib/jvm/java-7-openjdk-amd64/jre/lib/amd64 firefox

It works for the unix client and once the public testing is done (to see if this causes any other issues) i will make an automated script to fix it :)

Hey @HikariKnight! (By the way--LOVE the Unix client!!!) So, I just run the command in terminal and it works for the client as well as other browsers, or just Firefox? – Ryan McClure May 16 '12 at 3:08

sadly after some proper testing the above do not work :( however there are solutions provided in the wiki just search for Linux Known Issues and you will find the article

And the fix i provided above (which do not work for the browsers, only client or java directly sadly) is integrated in the version 3.0 of the unix client, glad to hear you like it ryan :)
