I don't think VR is supported, and yeah, even a low ping would make it a vomit comet anyway.

Here's the pricing: https://www.paperspace.com/pricing You have to sign up and then request access to the GPU instances (each instance type has to be requested individually, unfortunately. I found the GPU+ instance to be a little underpowered, and the P5000 has been performant enough that I haven't bothered to try the P6000). I can take up to 24 hours to get access. Once you have that though, you can create an instance with the parsec image and it comes with all the drivers, as well as steam and EA origin pre-installed. The parsec client by default starts up without admin mode, which crashes a lot in my experience, so I log in using the browser client and restart the parsec server as admin manually. It's basically ready to go out of the box and the longest part of the setup is just waiting for your steam games to install.
