Here's another option, and I'm serious.
Dumb down your systen - cutting edge technology is over-priced anyway.
Save $1000 bucks and buy C4D and Interposer pro.
Import your Poser content and render with C4D which is a real 3D program, not just a plaything, and join the big boys.
*(ducks hisses and thrown tomatoes)

C4D rocks -

• program opens in 3-4 seconds
• render while you work (renders separately to GUI)
• massive rendering options - eg. 10  AO settings
• select infinite number of objects or textures (materials) to adjust at once
• click and drag textures
• copy/paste objects in scenes
• multi-pass rendering to multi-layer files
• true radiosity rendering
• solid, fast render engine, even at highest settings

Really good - warning if your render won't work (memory) BEFORE you try to render. No crash or hang, just go back and reduce your settings. Nice!

You know I'm only joking Poser, not.
