Dual graphics card rendering in Substance 3D Designer/IRay?

[Arek.O]

Hi
I'm wondering if it's possible to use one graphics card in the computer and another external e-gpu to render a scene in Substance 3D Designer/IRay?
In the Substance 3D Designer/IRay settings it looks like this is possible?

On my end, there may have been a lack of drivers during installation.
But is it possible to use two graphics cards if there is room for it in the program settings ???
Regards

Hello @Arek.O,

External GPUs are not supported, as per our system requirements.

You may nonetheless try your luck, as some users have reported success with configurations such as the one you describe. However we will not be able to troubleshoot issues related to that use case.

I appreciate your understanding!
