Personally I am not really aiming for Photo realism and I am not skilled enough to know how good textures are technically, but I do tend to use a lot of different textures and modify them to my liking.

My favorites are 3DA Agatha by 3-DArena when using V4 and Master Skin Resource 7 by 3Dream when using Dawn as they help me create figures a little nearer middle age (in my view at least) than the teen to mid twenties that seem to be the main focus.

 

 

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.
