AMD 7900XT low gpu usage on Align Photos and Build point cloud

CPU limited (is a six years old cpu), Threadripper has plenty of pcie lanes (64).

The last slot you are running is at 4 Gbps speed. So pretty bottle necked.

Metashape doesn't need to transfer 4GB every second between RAM and VRAM , so it is still OK.

That slot was for my sound card before.
I said in a previous post that my cards were in two slots at 16x (16gb/s) and one at 8x (8gb/s).

4Gbit is not 4Gbytes, its 0.5 so it is extremely slow and unusable for any work. As the motherboard limits the slot to PCI 2.0

No it can not, in the manual for the motherboard it gets limited to PCI 2.0, You should read the manual for the motherboard when using PCI slots.

If it limits that slot to 2.0 standard, then it is still 2GB/s which is enough speed for uploading data to VRAM.

Its the bottle neck.

I installed the cards in the pcie 3.0 ports, 16x and 8x speed, I don't know where you get that I installed a GPU it in the bottom port (physically impossible with any of my cards) that works at pcie 2.0 4x. There I put the sound card...
