You could increase the amount of memory that the JRE can use, although RS may have its own cap I'm not sure. 1.Attempt to run RuneScape and you will see a small Java 'Coffee mug' icon appear in the bottom right of the Windows taskbar (the system tray). 2. Right click this icon and select the 'Open Control Panel' option. 3. Select the 'Java' tab on the window that appears. You should see two panes. 4. Select 'View' under the first pane, which will be labeled 'Java Applet Runtime Settings'. 5. You will now see your installed Java versions. In the fourth column (titled 'Java Runtime Parameters') double click, and you will have a text entry box. 6. Type -xmx128m into the box. The 128 part tells Java to use up to 128mb of RAM instead of the default, which is much lower. To allocate more or less, just change the number. 7. Click Apply and OK, then close your browser (if open) and re-open.
