Valve expects that its recently announced Steam Deck portable gaming console will be able to run “really the entire Steam library” on its 1280×800 LCD screen at frame rates of 30 fps or higher.
That’s according to a recent IGN video interview in which Valve Hardware Engineer Yazan Aldehayyat said that “all the games that we wanted to be playable had really good [performance], a really good experience” in Steam Deck testing. Valve developer Pierre-Loup Griffais expanded on that by saying that “all the games that we wanted to be playable” means “really the entire Steam library. We haven’t really found something we could throw at this device that it couldn’t handle yet.”
Griffais said initial prototype testing for the Steam Deck focused on older games in the Steam catalog and that there were “games that were coming out last year that just couldn’t really run very well on the previous types of prototypes and architectures we were testing.” On the finalized version of the hardware, though, he said the company has “achieved the level of performance that is required to run the latest generation of games without a problem.”
“The entire Steam catalog is available to people who have this device,” Aldehayyat added. “That’s where we knew we had a product that was going to deliver the experience we were looking for.”
Aldehayyat attributed Steam Deck’s wide compatibility in part to “future-proofing” internals that include a custom APU incorporating AMD’s latest generation of GPU and CPU technology, as well as 16GB of LPDDR5 RAM. Griffais added that the extreme performance scalability of modern PC games also helps Steam Deck achieve a playable frame rate at its native 800p resolution (which is relatively low compared to desktop gaming PCs).
“If people are still valuing high frame rates and high resolutions on different platforms, I think that content will scale down to our 800p, 30Hz target very well,” he said. “If people start heavily favoring image quality, we might be in a position where we might have tradeoffs, but we’re not in a position where we really see that yet.”
In a follow-up tweet late last week, Griffais clarified that the 30 fps target is the “floor” for what Valve considers playable: “games we’ve tested and shown have consistently met and exceeded that bar so far. There will also be an optional built-in FPS limiter to fine-tune perf[ormance] vs. battery life.”
Steam Deck will come preinstalled with Valve’s Linux-based SteamOS, which can run native Linux games as well as thousands of Windows-based games through a Proton-powered compatibility layer. Steam Deck owners will also be able to install their own OS on the device, including Windows.
Elsewhere in the interview, Aldehayyat said Valve spent a lot of time optimizing Steam Deck’s SD card connection so that games stored there should be “comparable” to those stored on the internal SSD storage. He added that the NVMe storage was connected in a separate module and not directly on the motherboard, which could suggest it will be possible to replace as time goes on.
