The original Coco frame times were 1000hrs/f, thanks to millions of light sources (and coming in at 30GB to 120GB of scene data). But engineers got that down to 50hrs/f over the course of production - light acceleration structures that have now ended up in RenderMan 22. (These numbers are single core benchmarks, so you then need to scale by some factor of numbers of cores you have available). In general, I think it’s the huge scene data size that keeps feature films mostly on the CPU. https://www.fxguide.com/featured/rendermans-visuals-for-coco/ https://www.fxguide.com/featured/rendermans-visuals-for-coco...
