Windows 7 lag spikes - related to map size?

i only have lag when leaving pap's map. other than that it's fine. :f6:

This is what my RAM usage looks like simply by AFKing in Pap's room after it died. MS normally uses about 250-400 MB of RAM, but it spikes to ridiculous levels at Pap, Zakum, and Kampung. Crazy memory leaks.
