Hi John- IF Rhino 5 supports 2-3 video cards using SLI Nvidia setup, does Rhino itself parse threads to the GPU’s for processing floating point calculations?? In other words, if I had a quad-CPU core and three SLI Nvidia cards connected, are all the threads processed on the CPUs or are some passed over to the GPUs?? If not, it would make a lot of sense for rendering! Thanks, Stuart
