Since i got poser 5 i always use the firefly render. I setup a bit complex scene today and after i got tired of the long rendertimes i switched back to p4 render in poser 5. and rendering the same scene took 2 min in p4 renderengine versus 20 min in firefly,no more swapping like crazy to the hd and waiting 2 min after rending till poser recovers. ( i have a AMD 2400XP and 768 mb ,so no weak machine) So, why is firefly swapping to the hd like crazy. Seems its more busy with swapping than with calculating,and why does the p4 render needs no swapping. for he images decide which is ff and which is p4. modells: hanksters temple ruins (great model, dodgers dungeonlights,and moonprop free from nerd
