Runescape lag

Ok heres the info, I play on the runescape client, not a big fan of the web browser while playing, but the same thing still happens either way, so it wouldn't matter.

Whenever I go to open a new runescape client, and start to play, it's EXTREMELY laggy, literally less then 1FPS.
But if I just wait for like 10-20 minutes, the lag just COMPLETELY goes away.
and I can play as if nothing was even wrong.

i know my computer reaches the requirements to play RS.
I just don't know why it does this, any help??
