I have been caught out by this in the past.  I reloaded an old scene and did some changes and then started a render which I abandoned as it the precalculating indirect light was clealy not running as it should.  I did that three times until finally I let it complete the render.  Only when I noticed the cursor changed when I hovered over the the completed render and  I could pan across the image did I realise I had saved the orginal scene with the render dimensions way up for a special render.

 

 

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.
