Without the Fog cube and the Smoke objects (both ScatterVolume) both Poser are computing the scene below 15'. Poser 13.1.449: ~211 seconds using OptiX and ~264 seconds using GeForce Poser 13.0.339: ~45 seconds using OptiX and ~59 seconds using GeForce The settings I've used are the default 'OptiX high' except that the pixel samples are set to 20 instead of 25 and the bucket size set to 2048 We are happy to report that an exciting new figure is in the works for Poser 13 and will arrive soon with delivery accelerated by the new content creator tools.

As usual with each major version of Poser, we offer a 21-day free trial to ensure the software meets your needs before purchase.
