I'm lagging a lot lately. Often when I click somewhere my character won't perform the action for a couple of seconds - it'll just stand there but I can see everyone else around me moving just fine. Prayer flashing has become very difficult and everything is taking longer to respond. I can't even walk in a line without my character stopping every couple of steps. Even when I'm in a world with 25 ping. At first I thought it was my internet, but a couple of clan mates are telling me they're having the same problem.

 

Is anyone else having this problem as of lately?

I haven't had any troubles with lag recently but You can try clearing your JagexCache then re-load Runescape by running around to the areas that you commonly use.

Another solution could be simply restarting your computer or updating your java to version 7 Update 4

You can update/install java here:

That didn't work for me. It's not a FPS issue.

Do you play from the website or the game client? Mine is running fine on client.

Client.

 

I'm reading that a lot of other players are having the same problem on the Tech Support forum. They say it has to do with a high input and very low output or something, which thus results in big delays appearently.

 

Edit: changing to a German world fixed the issue. Weird.
