Omniverse Audio2Face Environment

I installed it via NVIDIA Omniverse Launcher to run Omniverse Audio2Face.
However, the GPU specification says it is possible in RTX, so when you run it, an error appears in the console window.
It doesn’t seem to be working properly. So should I buy an RTX GPU and use it as a StandAlone?
I wonder if it is possible to use a server with RTX GPU as a network.
I have a server with Titan RTX installed and I was wondering if there is a way I can use it.
I found RTX Virtual Workstation (vWS), and I was wondering if it would be possible to use it.
I also know it costs money, but I’m curious what it’s going to cost. You can also point us to a site where you can find information about costs.
Finally, I wonder if there is a way to use NVIDIA-managed cloud servers instead of the servers we have.
If so, I would also like to know about the cost.
