I have a iMac 3.06GHz Core 2 Duo, 8GB RAM and Runescape really lags when I play it even on lowest setting. I have no problem with World of Warcraft though but I lag on other Java games like Minecraft (single player client so don't say it's ping). How can I fix it? I have already allocated more RAM to Java but it didn't help. Please help me!

I'ts probably your internet connection or a server-side problem. If it is a server-side problem, there isn't anything you can do.
