I looks as though some of the older content in my runtime is going to have to be used with care.  I have an aging GTX 1080i graphics card which I found to to my utter disappointment would not work with Poser 11 but thankfully did with Poser 12.  It has been working fine with Poser 13 but today I tried to render a scene with a lot of old content but all I got was a grey screen.  Looking at the logs I am getting a Cuda warning similar to the one already shown here.  The scene will render using the CPU but there is still a slight issue with some old content in that I find glass looks as though I has been set up for emissions, I have seen this on content created by three different vendors so far.  

I don't really blame Poser 13 for this as, despite all the efforts made to make it backwards compatible, there is bound to be a limit somewhere.  I think that using textures from old content will continue to be an issue as we move forward.   I thought the glass problem was due to a cellular node plugged into the defuse colour with a setting of 2+ on the diffuse but changing this alone does not sort the problem as both the specular and reflection needs to be looked at.  I now use a PhysicalSurface node to correct the problem.

 

 

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.
