The way I look at, a hammer can't do a job that a screwdriver is designed for. As much as I dislike Poser's limitations it's still useful from time to time. I needed just a humanoid shadow for a recent project and whiz bang I got the results I was looking for quickly. Would I try to do animation production in Poser? Prolly not. I agree that Poser's lights are primitive, though I'm not sure that's what makes it so slow. Though mileage varies, I get relatively speedy renders out of Firefly.
