I was rendering a series of images yesterday, and actually kept my Poser session running for more than 5 hours. Around mid-point in these sessions I did a render of a big figure in a 1000X1000 pixel window, and found it took about a half hour to render, which seemed pretty excessive. But a couple of hours later I did another similar render, and it took about 45 minutes. Then, my last render of the day was a smaller shot, about 300X500, a closeup of a hand. It took over 45 minutes and never finished rendering-- I eventually used a screen capture to get the parts of the render I needed and then canceled it. I'm not quite sure, but I think the render of this last shot may have gone to sleep a few times, and only been reactivated when I hit the return key to display the screen (screen saver turns the screen black when I'm not actively imputting to a session.) I also noticed during the latter part of the day that Poser was responding very slowly to posing commands. I was working with a single figure, David, who had about the average amount of morph targets loaded on him. I've only been using Poser 5 for a short time. This kind of experience makes me think that I should go back to using Poser 4, or experiment more with Daz3D studio (which has its own problems, unfortunately.)
