I think the answer to this is that the images are being displayed as OpenGL textures, which makes it possible to do the cool crossfade effects. I'm almost sure that this is the case with the Slideshow Screen Saver, which uses zooming and panning in addition to the crossfade. I'm not sure how the machinery of this all works, but i think i read somewhere that because the images are being displayed as OpenGL textures is the reason for the fuzziness. Anyone care to corroborate my story?
