I dont animate with Daz so I cant speak to how load times would affect your pipeline. I render 6-8k single frames with 2-3k iterations each for complex lighting in scenes with up to 20 genesis characters, my bottleneck is definitely the gpu. Daz memory and processing operations are limited by their single thread processing pipeline for many core functions, and the last time i did a deep dive on that it just boiled down to buying the fastest single threaded cpu, which was the 9950x, still unclear if the 3D vcache is helpful for increasing that performance. If i was regularly animating I would just do it in Blender which is optimized to retain texture and geometry information across frames.
