Hello zagnimarco1,

Can you please provide the screenshot of the GPU preferences window from PhotoScan and also the processing log related to any GPU-supported task (image matching or depth maps generation, for example)?

[zagnimarco1]

I'll do as soon as possible thank you

Probably i'm wrong, looking the  task manager  seem only gpu have 3d activity but triyng    with 1 or 2  enabled the the result change, taking  several seconds less , the strange thing is only gpu have the fan  at max speed the second gpu is with  0 rpm and the temperature is   pretty cool.Anyway  this is the screenshot and the log.

And another problem occour  using ultra high settings....Low memory?

Hello zagnimarco1,

I don't think that Windows 10 Task Manager shows the GPU utilization in the default screen properly. Please try to go on the GPU page and switch one of the graphics there to Compute_0 or Compute_1. Or use dedicated utilities to monitor GPU activity, like GPU-Z or NVIDIA SMI, for example.
Additionally I recommend to disable CPU utilization in the GPU preferences tab when at least two GPUs are used.

To reduce the memory consumption, I can suggest to check version 1.5.0 pre-release and enable Fine-Level Task Distribution in the Advanced preferences tab. Also you can try new meshing method directly from the depth maps, skipping the dense point cloud.

It was the same link but not the same Build (it has been updated 3 times since then).
