Downsampling-3.DSM, Orthomosaic and Index

After “Substep Ortho dsm finished” the next step is “Substep Ortho dtm started” Then “Downsampling” has started to run.

It started last night 23 : 12 : 15 and now next day 18 : 31 : 00 it is still running.

How will I know how long it will still run till completed? The processing “wheel” is still turning.

I use Pix4DMapper, large format photo module.

I have the Phase One iXM-RS150F camera with a RS 90mm lens.

The project I surveyed is three image strip road corridor of about 8km and a total of 167ha. a Total of 911 Photos. Each photo is 435Mb. There are 23 GCP’s. GSD is 1cm.

My Windows 10 Pro 64-bit PC has a AMD Ryzen Threadripper 3970X 32 core Processor CPU, 128mb ram, NVIDIA GeForce RTX 3080 Ti (ZOTAC) Graphics card.

Is this usual to take this long? Could it because the image size and GSD?

Can anyone shed light on this please.
