A bit more detail.

Resolutions 1440x900 and 1360x768 don't work. Anything lower does. I have a widescreen monitor though, and all the other resolutions are 4:3. And when I do put it in 1440x900 or 1360x768, I only get the graphics to work when I turn of HDR. But then everything (avatar, terrain, objects) go transparent, so it's a really weird effect. The funny thing is that if I start up the game and don't change anything it appears to run at 1440x900 eventhough the graphics menu says 640x480.

Oh, and this has nothing to do with my problem, but is it me or do the female legs look unproportionally long? :p
