40 M triangles is an embarrassingly low number with 6GB of GPU VRAM required for this level of great software. I have been asking support for many months and no one can give an approximate answer for a time table? I have a NVIDIA RTX A6000 with 48GB ECC VRAM with enough space and power to install another A6000. Our small RC projects have 400-600M triangles with only 1500 images @ 50Mpx each.
