I agree that you shouldn't need more than one render engine. But, based on the R3 sample renders I've seen, It's a major step up from Firefly. If they can get it to work right, I'd have it in a second.

 

Luxrender, which Reality converts the Poser files for, is good but in many cases firefly can get very close.  I still use both but the real feature I miss with firefly, after using Luxrender, is the ablity to suspend a render and resume it at a later time.

 

I have a set of runtimes that I have been using since Poser 6 and all I ever do is let Poser install its content into it default folder and then point the new installation to my runtimes.  I have now done this for Poser 7, Poser 8, 2010 and 2012 with no problems at all and takes minutes.  I have little doubt that it will all work well with 2014.

 

 

I use Poser 13 on Windows 11 - For Scene set up I use a Geekcom A5 -  Ryzen 9 5900HX, with 64 gig ram and 3 TB  storage, mini PC with final rendering done on normal sized desktop using an AMD Ryzen Threadipper 1950X CPU, Corsair Hydro H100i CPU cooler, 3XS EVGA GTX 1080i SC with 11g Ram, 4 X 16gig Corsair DDR4 Ram and a Corsair RM 100 PSU .   The desktop is in a remote location with rendering done via Queue Manager which gives me a clearer desktop and quieter computer room.
