Hi guys.
I’m using WebODM and I point out that I used the installer for WIndows (so I don’t use Docker). I noticed that during processing the GPU (nVidia RTX3060) is not used, only the CPU works. Is it possible that there is some configuration file that needs to be modified? I have the latest nvidia native drivers, and the latest version of WebODM updated. Thank you very much for helping!

If you do a search for CUDA you’ll find plenty of posts that explain this

Welcome!
Martin gave you a great place to start (Seriously, Discourse [our Community software] has amazing search).
But to give you a summary, very likely your card doesn’t have enough VRAM to fit the uncompressed texture dimensions of the input images into the CUDA acceleratable texture dimensions.
A slight downsample of the input images might help.

How were you seeing if the GPU was being used? Did you look at the windows task manager or did you get a notification in the task output to say that it GPU failed falling back to CPU? Most of the time your machine is processing images it is working on processes that don’t use the GPU, so sometimes you might miss seeing it use the GPU if you’re watching using the task manager. If you have a look at this thread you can see a great chart that shows the sections that do use GPU . On the RTX3060 if you try and use ultra settings it won’t process on the GPU.
