Multi-Process Rendering

Hi,

I have a question about Multi-Process Rendering:

  1. I can’t find any documentation on this concerning hardware setup. So, I’m wondering, is this a single computer with two GFX cards in it?
  2. Since Multi-Process Rendering doesn’t need NVLink, can I use two RTX 4090 cards in the same machine?

Many questions will come, but first, I would love to see the above answered. I’m in the process of purchasing a new node for our studio.

Thanks!
