Well I set it to render in a separate process and do far i am up to 2500 on a side so that seems to have fixed my problem for now. Though Poser does force my laptop to groan and complain about memory usage even when setting poser to low and FFRender to high. I just ignored all the complaints and let it continue rendering.

 

Thanks for the advice, I have not had time for much poser lately so I have forgotten a lot (damn I need to relearn VSS from scratch i think, hopefully it all comes back easily)
