Thank you guys, this is helpful.
This particular block is comprised of ~4000 medium format images as an added bit of info.
In the preferences>advanced>tweaks section there is an option, "main/refine_max_gpu_multiplier" which has a value of 2. I cannot find any documentation on this anywhere. Any ideas as to what it does?
Which is your photos resolution?
My times for "detecting points" are with 21MP photos (5472x3648), Phantom 4 rtk.
I tested with a similar project (3500 images), with one 2080 Super, and the time to finish "detecting points" is ~27 minutes.
Without GPU, the time up to ~1 hour 50 minutes.
We have similar CPU and GPU, and you says your time is 6 hours for 4000 images!!! or the image resolution is very very high or something more is happening.
About "refine_max_gpu_multiplier" i don't know, the only thing i change on metashape are enable all GPU and turn off the CPU for GPU usage.
