Using 2 different GPUs + CPU / RAM all together?

Hi, I'm falling in love with your software and so I have many questions.
Speaking of hardware, I wonder these two things:
1) can I use 2 different GPUs in the same system? Does Faceswap use both of them even if they are different? (clearly I have to set batchsize divisible by 2). In practice I would continue to use my current R9 270X + RTX 2060 Super
2) why faceswap while using the GPU can't also use CPU and RAM? It would still help.

Yes, you can use multiple GPUs but it's only worth it if they're the same GPU. AMD and Nvidia cannot be mixed.
A single 2060 super will be anywhere from 5-20x faster than your R9 270X.
Synchronizing multiple devices involves a lot of overhead. Sometimes (such as your AMD GPU and your CPU) would actually be slower than just running on the GPU alone.
CPU < AMD GPU < Nvidia GPU.
