Allocate more RAM to the Java Client on Windows

 

 

 

1

Navigate to: %USERPROFILE%/Jagexcache/Jagexlauncher/runescape

2

In this folder find the file called 'runescape.prm'

3

Open this with Notepad

4

The file should look like this by default:

Djava.class.path=jagexappletviewer.jar
Dsun.java2d.noddraw=true
Dcom.jagex.config=http://www.runescape.com/k=3/l=$(Language:0)/jav_config.ws
Xmx256m
Xss2m
XX:CompileThreshold=1500
Xincgc
XX:+UseConcMarkSweepGC
XX:+UseParNewGC
jagexappletviewer

(The line '-Xmx256m' may also have a different number, such as '-Xmx384m', dependent on client version)

5

Replace the line beginning: '-Xmx' with

Xmx512m

6

Save and close the runescape.prm file and restart the client

 

PLEASE NOTE - ALLOCATING MORE THAN 512MB OF RAM CAN HAVE A NEGATIVE AFFECT ON PERFORMANCE

Type in the following command (This command assumes that the official RuneScape client is located in your Applications folder):

< key >VMOptions.i386

Save the file and restart the client.
