Steam Deck lead reveals Valve is funding ARM compatibility of Windows games “to expand PC gaming” and release “ultraportables” in the future.

Griffais didn’t confirm specific devices that Valve is working on, the SteamOS lead explained that they’re “excited” about creating potential ARM-based devices. “I think that it paves the way for a bunch of different, maybe ultraportables, maybe more powerful laptops being ARM-based and using different offerings in that segment,” he said. “Handhelds, there’s a lot of potential for ARM, of course, and one might see desktop chips as well at some point in the ARM world.”
