Bug Reports / Blending Textuers does not select optimal GPU

« on: February 16, 2024, 07:04:14 AM »

Hi,

Not sure if this is a bug, but at the very least is a feature request to try and use the GPU with the most memory when blending textures.
This I believe is the same as reported here https://www.agisoft.com/forum/index.php?topic=14389.0 back in 1.6.1

Metashape 2.1.0
I have 2 x Nvidia 3060 GPU in my machine
One has 8GB RAM
One has 12 GB RAM
If I leave them both enabled when blending textures it tries to select the card with 8GB RAM and fails, and reverts to CPU.

With both cards enabled in preferences
