There seems to be grumbling about the render times in the DAZ forums. There is a post that "image" based textures give the biggest render boost. They also state that DAZ found out why Corel was not supporting the MAC version since the improved code only works with Intel processors and Nvidia cards. (at least thats the way I read the posts.) So single processor users of Bryce 5 using procedural textures may see very little improvement and in fact may see an increase in the render times. I will be very curious to see the outcome of this.
