Agh damn, its only for the 200 series or the 9, 100 and 200? it says so in the website. :\ There is really no performance hit? Anyway, I'm on a 8800GT, so no fun for me :(
Back then I was still counting triangles individually in my models and worried about the ~200 triangles articulated hands take. Oh and I considered a head of 200 triangles "excessive".
