Steam deck has been going under some testing by the Valve developers and testers internally. All games tested so far have been running at a smooth 30fps. So the developers are pretty happy and confident about the new system that it hasn’t had any problems with running any games so far.
Steam deck is Valve’s new portable PC based off on the design from Nintendo Switch. Honestly its a very elegant looking device. Also given that you will have the power to play pc games on the device is also very promising. The device can be hooked with a TV as well to give a crisp display on the television screen whenever it is required. Device comes with three variants with the lowest one starting with $400. If users would like some extra options and storage then they can go with the $530 one.
“We’ve been looking at various games over the past few years in the back catalog,” said Valve coder Pierre-Loup Griffais. “But the real test for us was games that were coming out last year. They just couldn’t really run very well on the previous types of prototypes and architectures we were testing.” (source: https://kotaku.com/valve-says-it-hasnt-found-a-game-that-the-steam-deck-ca-1847358340)
