Poser 13, for speed of SF rendering and the easy IBL backgrounds. The updated legacy figures made me re-look at these assets.

I keep Poser 11 standby on a retired rig in a corner just in case I needed some old scripts but I cannot remember when I last fired it up.  

Poser 12 is still installed on my day-to-day system but I hardly use it. Whenever I do it just strikes me render is so slooooooow.
