Scratchy shadows on character models?

[Martyr]

Can you actually play at 16xCSAA with good framerate?

I run it in most places at 60 FPS with a GTX-460, an i5, and water cooling. Temp gets up to about 45C.

My framerate tends to drop in Gridania, though. I get 30-50 FPS there. I think it's all the shadows.
