timoteo1 I can't help you with animation, I am still learning, but rendering times, with Poser I think really has to do with the textures themselves, especially if they are high definintions, and the Boolean works great, but that always has for me. They only thing I really notice is the difference Vue 4 and Vue Pro has on different OS...I really think that is a huge key. Can't prove it, but I have seen many improvements on Vue 4 and Vue Pro when they go on my old OS and then go on my new OS. I always use my XP, but I use to have ME first...ME was okay, but XP is great with it. Sharen
