After peppering Google employees with questions regarding Stadia’s latency, pricing and supported devices to mostly no avail, I got my hands on one of their new controllers and pressed play on the Doom Eternal gameplay they were showing off on a big-screen TV.

Things started off pretty ugly. The frame rate dropped to a fast-paced PowerPoint presentation, the resolution dipped between 4K crispness and indecipherable blurriness and latency seemed to be as much as a half-second. As the Google employees looked nervously at each other, someone grabbed the controller from me and restarted the system.
