I wonder if it isn't texture filtering that is causing all these blurry comparison shots? I noticed that the highest auto settings automatically turn it on, which Ronstuff at least would say is a no no. (and will mess up V3 texture seams if you don't doctor the textures your self.) I also noticed that the default shading rate in the top pic was set WAAAAY too high. Try .5 at least. I also agree about the post filter setting. Box sux bigtime. as for black line artifacts, these have just shown up in some of my shots in Poser 5. Nobody has come up with a reason. It seems very random as the same exact setup shot from a different angle may have no artifacts. On the plus side It doesn't happen very often. also 11 hours sounds INSANELY too long. I've rendered whole animations with multi figures and raytraced reflections in that time. admittedly that was at 853x480 though.
