I am still not convinced but then I have not played with Unreal as I have no interest so you may well be right.  Just find it hard to believe that a Renders in Poser, Vue the rest take time to do a quality render.  If you can get the same quality realtime it would be all the rage but then that is very different from being a 'Buzzword'.

 

 

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.
