Lag problems.

[FuManchu]

For some reason, my Graal client is lagging on multiple server. It's the kind of lag that makes your character move slowly. I've used a Windows Vista computer for a year, and it ran fine with Graal for many months after I found out Graal doesn't lag when I don't use fullscreen, or a Graal screen close to it. Now, all of a sudden, Graal is lagging again for me, and I'm not at all sure why.

I think a few other people have this problem. I mainly lag is populated areas, or areas with a lot of NPCs (like lights). Examples of these places are the UN and Zodiac event centers.

The rest of my computer seems to be running absolutely fine. I haven't noticed slowness in any other program.

Anyone have any suggestions for me?
