windows xp and 2k are crap. They are not "modern operating systems" some of the bugs in windows xp were in windows 95. The pc itself could be a lot better if someone else made a better operating system and dos written in machine code and not like windows in any way. I doubt that poser will be a utility for daz unless daz does things very differently, and so far, from what I have seen, there is not very much difference between poser 5 and daz studio renders. Poser started off being a utility for people to have figures in the pictures that they rendered so the renderer in poser wasn`t the best. OpenGL is okay if the computer is working perfectly but with windows that is not too often.
