The Steam Controller will not work outside of the app, on mobile phones.

The app is slated to launch the week of May 21 and will feature support for the Steam Controller, MFI controllers, and more across both platforms. Players will also be able to use two finger pinch and pan gestures to zoom in as needed on the screen. The app does tinker with the view a bit, adding black bars on the edges to deal with aspect ratio differences and the video is scaled to handle different screen sizes. You can go into the advanced streaming settings and tune streaming resolution and bitrate for the best experience in your setup.” “If you have a powerful rig, wired network, and very good client device, it’s possible to stream at 4K 60 FPS. The quality bar for the stream is 1080p at 60 FPS with good quality for most scenes, he said. At the start of the beta, the app will support Android 5.0 or newer. He added that at launch the app will support any iOS device running iOS 10 or newer, and any Apple TV running tvOS 10.3 or newer. On the Android side, Valve plans to initially release in beta so it can do more exhaustive testing. There is a small amount of latency that will affect competitive multiplayer games, and the larger screen of a tablet is preferred for games with lots of text or small details.” “In general you can play any game that works with a Steam Controller.

“Under the hood we’re doing real-time encoding of H.264 video, sending it over a custom low latency network protocol, and decompressing it on the client,” he said.

Lanting said that the app is using the same Steam In-Home Streaming technology used in the Steam Link.
