I'm not 100% sure, but I think this has more to do with your Page File settings for your computer than Poser the Program. I don't know how to do it, but I know it can be done. You can increase the Page File maximum. When rendering with Firefly, I've noticed that it's not Processor speed that spikes, but Page File Usage. Someone who is cleverer than me will hopefully post an instruction on how to adjust your Computer Settings to increase your PF maximum. Hope that points you in the right direction. Chloe
