Steam Machine gains AMD FSR 4.1 via Proton Experimental
Valve has brought AMD FidelityFX Super Resolution 4.1 to the Steam Machine through Proton Experimental, the Linux compatibility layer that bridges Windows games to SteamOS. According to Valve's announcement, the upgrade arrives as a software update rather than new hardware, allowing supported titles to render fine details such as foliage, strands of hair, wire fences, and thin objects with fewer upscaling artifacts than earlier FSR versions. The route through Proton Experimental underscores Valve's continued reliance on the Linux compatibility stack as the primary pipeline for pushing cutting-edge graphics features into SteamOS without waiting for individual developer patches.
SteamOS 3.8 updates fix performance issues on Steam Deck
Two new SteamOS releases, SteamOS 3.8.15 on the stable channel and SteamOS 3.8.23 on the beta channel, target a performance degradation issue that had affected Steam Deck users when composition was required, including some FSR-enabled scenarios. The stable update also delivers an HDR fix for Assassin's Creed Black Flag Resynced, along with broader security and stability improvements. The beta channel carries the same HDR fix plus a correction for delayed Proton start times when no capture device is present, signaling Valve's continued effort to resolve lingering performance regressions on Steam Deck hardware.
Valve opens Steam Machine reservations at $1,049
Valve has opened reservations for its Steam Machine, a compact living-room PC running SteamOS 3 and priced from $1,049 for the 512GB model. The company expects to fulfill all current reservations by the end of 2026, with purchase invitations issued daily according to regional queues and product variants. Recipients have a 72-hour window to complete the transaction once the email arrives, and waitlisted users move into the reservation queue only after regional quotas clear. Valve positions the Steam Machine as more than six times as powerful as the Steam Deck, a figure intended as an architectural comparison rather than a guarantee of sixfold framerates, with enough headroom for 1440p gaming and FSR-driven 4K-like output on a television.
MetaPCs launches Steamroller prebuilt with SteamOS
Independent system builder MetaPCs has introduced the Steamroller, a prebuilt gaming desktop that ships with SteamOS rather than Windows. The Steamroller pairs an AMD Ryzen 5 9600X CPU with a Radeon RX 7600 GPU in a standard desktop chassis and is priced at $1,299. The launch marks one of the first third-party prebuilt PCs to ship with SteamOS directly, extending the operating system beyond Valve's own hardware and the MetaPCs Steamroller is positioned as a more traditional, upgradeable alternative to the living-room-focused Steam Machine.
CAD files and community customization
Alongside the reservation rollout, Valve released official CAD files for the Steam Machine's exterior under a Creative Commons license. The release is intended to give modders and third-party manufacturers exact dimensions for designing custom faceplates, mounts, and accessories, a deliberate nod to the PC modding ethos that Valve says distinguishes the Steam Machine from locked-down consoles. Combined with SteamOS features such as support for third-party software, Proton compatibility, and the option to dual-boot Windows, the CAD file release signals Valve's intent to position the Steam Machine as an open PC rather than a closed appliance.
