Not so good news then, not if it doesn't make use of the GPU, and you still haven't said if Cycles runs in the main Poser viewport or a seperate window.

If it's a window, we'd be better off using Reality cause at least Reality makes use of the GPU as well (if you want it to).  As a sidenote, I hope Baggins' recent scarcity on the forums means he's the one working on the SuperFly nodes and stuff.  As it's always Baggins who ends-up having to mentally reverse engineer the FireFly node system in order to document it's shortcomings for the members here, I really hope he's the one doing the node stuff.
