Maple Story lagging too much

For me it only affects my laptop. Regardless of map. I can be standing in one of the Leafre houses and the CPU will be 100% and memory 2.5GB. My desktops, on the other hand, can handle the same maps the same way they always did, topping out at 800-1200MB and 30% CPU.

But it doesn't change the fact that both computers will not leak in FM correct? This still seems valid for me, and going through the trouble of checking every map is a bit tedious. I have heard of several people having issues with towns and Ardentmill, but I haven't actually noticed too much yet. Personally, even though my computer can handle the stress easily (meaning I notice almost none or just no lag at all) it has nothing to do with stopping the leak even when somehow its at 2.7-3gb ram usage and 20% CPU meanwhile my laptop would easily start to sit at 100% CPU and 2gb+ ram usage and lag so bad it frames skips all over and freezes from time to time. Spec wise they're vastly different, but that wasn't exactly the point I wanted to get across. I would hope OS wouldn't contribute to leakages too but, I cannot be sure, both at 64bit windows 7 by the way. I have a guildmate dcing massively on a 32bit version of windows 7 for some reason.
