I have the OpenCL version of Luxrender installed and set it to use OpenCL in R3.  According to the stats during a render I have 8 threads on the CPU and one on the GPU.  I assume this means that it is working with OpenCL but I am not sure and don't know how to check.  Also not sure what impact it will have but I am just at the bottom looking up at this steep learning curve at the moment, but having fun.

 

 

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.
