Quote - my system gets pretty hot using poser with IDL ... I'm thinking Reality would bring it to its knees? Onboard graphics..AMD ..but

 

 

It depends on the system really.  I have had some firefly renders last more than 24 hours.  Once the processor is running at 100% it will find the levels of cooling irrespective of what software is using all it's power.  So I guess Luxrender would be no different to Poser on most scenes

 

 

 

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.
