Will i benefit from additional GPU

[chrisodiachi]

I am currently running Agisoft on an Intel Core i9 - 7980XE 18 core workstation with an 11GB GTX1080 TI Graphics card. Recently, i tried to process 3,900 photos each about 18MB and the PC struggled with the dense cloud generation especially.

What upgrades can i make to this workstation to reduce processing time? Will additional GPUs be of any benefit?

How much Ram do you have? The Dense Cloud generation stage doesn't use the GPU so adding another won't help (it is used during the Depth maps generation) in this case but more ram is always good. Does your project require the generation of a dense cloud? If not then you could generate the mesh using the new method in Metashape (v1.5) which uses only the depth maps to create the mesh ans is GPU accelerated.

Thank you for your reply. We have 64GB RAM installed. Most often, we do not use the dense cloud but it is a necessary step we have to go through to get a terrain model and orthophoto, isn't it? Is there an alternate method in Metashape to generate terrain models without a dense point cloud?

In any case, I will get more RAM and see if there is improvement

Hello chrisodiachi,

Metashape Pro 1.5.0 offers the following source data for the DEM generation: Sparse cloud, Dense cloud, Mesh, Tiled Model.

So if you would like to benefit from the GPU, it might be reasonable to generate the Tiled Model from the Depth maps and use it as a source for the DEM generation. However, Tiled Model contains also the texturing step that is CPU only in the current release version, while depth and mesh generation are GPU-supported.
