I was one of the early adopters of the old Google Stadia cloud gaming service. I even purchased the Google Stadia controller around 2021. You know, pandemic and all.
It works perfectly on Steam wired via the controller’s USB-C to the PC’s USB. Or, you can set it up for Bluetooth here…
You’ll need the Chrome browser (or a Chromium-based browser) to complete the Bluetooth update. The update process ends December 31, 2025.
