I think what Ydiss is trying to say - at least from my perspective, is that the TEXTURE of a skin (which is all it is) wont affect the FPS since the base polygon's dont change.

Now there are some textures that of course would take longer to load than others, but I haven't seen any skins that do this.

If someone can create a skin that lowers FPS - let us all know see we can download it (or I can come September 20th - god 2 weeks)
