Originally I did not experience any troubles but recently the client has become extremely laggy - it is unplayable and when botting, xp rates are harmed because of it.

Any ideas?

And yes, I am using the 'old school' preset.

Thanks in advance.

N.B. I do not lag whatsoever in the regular runescape client.

Update your java and uninstall old versions.
