Hi,
Thanks for the note. From your symptoms, it seems that there's
still an unresolved issue with the latest version of OptiX and some machines
that don't have GPUs installed. I will see if I can reproduce it here
and report that this is still not fixed to the OptiX developers at NVIDIA.
Best regards,
John Stone
