Shall I?

[mum_mom_mam]

I'm playing on the Runescape client and its still a bit laggy when I move to a certain place (etc im banking and it laggs 4 a 5 seconds]

Shall I exit out of java as its using the most memory usage?

If you exit java the runescape client screen will balnk out... it can't run without java.

You don't need Java with the client, right? ;o Well, you could do it.

You're running the game with the lowest graphics etc?

Well, I'm no expert in computers/programming, but the Runescape Client runs on Java.
I think you shouldn't exit out of it based on that.

What are your PC specs + Internet Connection?

Runescape can run without Java on the client?

Runescape can run without Java on the client?

No. As soon as he kills Java his client will go black.

The RuneScape client uses OpenJDK, which isn't directly dependant on java process.
As far as I know, you are free to kill java, if you don't plan on using Java in the browser this computer-usage session.
