Playing SteamVR games on the Oculus Quest, without owning a PC

Setting up your Virtual Machine

We'll be creating a new Virtual Machine on Microsoft's cloud platform, Azure. The VM will have a beefy GPU just like a home computer so it can be used for playing games.

1. Go to [the Azure portal][azure] and sign up or log in.
2. If you are on a Free account, first go to Subscriptions and upgrade it to a Pay-as-you-go plan. Don't worry, you will get to keep any free credits you have. Azure's interface is a bit slow so this will take a minute.

⚠️ Make sure to not include any support plan because they will charge you monthly!

Streaming an Android-based VR headset to your computer

Setting it up the first time

The first time you have to set it up with a cable. The Oculus Quest has a USB-C port (the one used for charging). Use this to connect to your computer.

Preparing your Oculus Quest

Your Quest needs to be in Developer mode. This is super easy, just open your companion app on your phone and go to Settings and enable Developer
