Yes you can use P3 instances on AWS as well as a T4. The difference is to use the RTX Virtual Workstation marketplace offering (AWS Marketplace: NVIDIA RTX Virtual Workstation - WinServer 2019) since it includes a discrete license for vGPU drivers on the P3 instance. Once you subscribe to this marketplace offering, deploy a P3 instance as usual. This won’t include the CloudXR SDK – you’ll need to download and install these pieces manually from our developer page. You’ll also need to open the Windows firewall ports manually for CloudXR.
