No engine so far does it all the time. Super Mario Galaxy, Monster Hunter Tri, Resident Evil Darkside, The Conduit show good effects sometimes but its not consistent enough. Texturing is hard on the Wii becuase you get better effects from using detailed mapping techniques but then have to use prerendering at times.
Consistent detail through graphics engines is missing on the Wii.
Maybe this will help
