Volter

well, you can adjust texture AA on each object now, which should help a lot :)

ie poser folk, or other major item, large in the scene, up close, or of extreme detial (say a really complex rugged sharp mountain) do need a lot of quality, texture AA etc, but many other things do not
lot of tweaking you can get really good renders, 1068x1050 (my fave resolution) out in 3 to 8 hours, depending, >8 hour ones usually are so long because of volumetrics enclosing the scene (like a metacloud used to create a fog bank, or the nebula my space scene was in that I used to make the tutorial)
thats on a 3 year old quad core
