What is likely to be the difference in render times between Poser 10 and Poser Pro 2014 (64 bit)?

I do not contemplate rendering large/complex scenes

System:
Win 7 64 bit
Core I7 processor
6 G ram
1/2 T SSD

I am aware that this is difficult, perhaps impossible, to answer with any degree of assurrance. I am looking for:
probably/ possibly and dramatic/significant/noticible/marginal
based on some user impressions

My apologies if this has been discussed elsewhere, I did search.

Thanks

Definitely a noticeable-to-significant improvement in terms of render times, overall, I'd say in PP2014.

Sorry, that's about as precise as I can be!

The progressive render option, for the purposes of fast, draft previewing, e.g. of IDL lighting results is also really useful, I'd say.

I am possibly seeing much less in the way of render artifacts when using IDL too, by the way... although that may even be since the last PP2012 service release.
