>Building on years of ARM architecture optimization and Proton compatibility development from the Steam Deck 2.0, Valve shocks the VR world in Q2 2027 with the Steam Deckard - a standalone headset powered by the custom Snapdragon Elite X2 that runs full PCVR games through Proton's mature ARM translation layer. What began as debugging handheld gaming performance has culminated in a wireless headset that seamlessly plays Half-Life: Alyx, Boneworks, and the entire Steam VR library at 120Hz without compromise, finally bridging the gap between standalone convenience and PCVR quality while maintaining full mod support and the open PC gaming ecosystem that made Steam Deck a success.
