Sure, it won't itself speed-up the animation but it's still the ideal environment. This is why I was hoping they would update the animation tools and animation interface along with it, and adopt Shane's figures as the default Male and Female. His figures look really well balanced when it comes to their poly-density to topology ratio, and they're even very nicely topologised.

Like I said in my requests, these things really need to come at once as they go hand-in-hand, but even if we don't get all of those things, the animation side of things is Poser's biggest, most embarrassing weak-spot and still desperately needs updating, even without a realtime renderer, because the figures can still animate in realtime in standard viewport mode, just as long as they're efficiently designed and animation friendly.
