I find that I need more polys in dynamic cloth simulations, cannot compromise on that. I also find that managing background props and figures to have lower polygons, more texture filtering (Poser Pro 11 can reduce polygons in-the-fly), will help in bigger scenes. I render on a Windows system, so we may be comparing apples and oranges. I have 32 GB installed RAM, an Intel i7-6700 running at 3.4GHz, and an nVidia GTX 1080 graphics accelerator card.
