Hey, yesterday I noticed something...
When I turn my character around, the shadows on her face change, but leave some sort of white-ish areas on the forehead and cheeks.
The areas are separated by white lines. I have the graphics set to Ultra, and I noticed that when I disable shadows completely, the white areas disappear, and only reappear when I enable shadows.
It's most likely bad shadowing in the game itself, can't expect much better shadows from a 2008 game which was already on an old engine.
Don't think that shadows are that important to anyone in this game anyway, later on you'll probably spend your time zoomed out as far as possible looking at either boss, timers and ground around you or other players, their buffs, debuffs and also ground around you.
