i tried using dynammic clothes alittle but, Just doing a 30 frame anim...the calculation takes unbearably long. Am i doing something wrong, or is it slow to everyone? i use poser 6 on a mac

Not slow for me. Sometimes it's take a few seconds to start, but finishes rather quickly. (minute or two)

It really depends on a couple of factors.
maybe the biggest factor is the complexity of the cloth, how many polygons are involved in collision calculations; if you are doing a animation with only a simple skirt for instance, you have a relatively low poly object only colliding with the hip & upper leg area of your figure. quick.
A more complex cloth which collides with everything but the head and feet is going to require big calculations for every frame, which is going to take forever.
I guess, as with everything else, it would help if you more clearly defined what exactly you are trying to do.

Yeah, i tried it and it was taking sooo long so i had to stop it. I'm gonna try to work only with short skirts. i'll tell you the results Thsi is what i'll try. 900 frame animation of a woman walking with a dynamic skirt

Let it run overnight, and see how far it gets.

The more severe the rotations of the hips the longer it takes to calculate.
