Have you tried playing on different servers? I don't know the online architecture for RS, but i'm assuming it gives you a choice about what server to play on. Some servers lag 24/7, no matter what your connection is.
Also, check your connection settings, and make sure everything is set up right. By that i mean check to make sure the type of connection you have is correct, any proxy/firewall settings, etc.
