- Valve confirmed to The Verge it's working closely with Intel, with Pierre-Loup Griffais saying Intel has "been doing a lot of hard work on getting the graphics stack up and running there and making sure everything's optimized."
- SteamOS 3.8 ships with "initial firmware for upcoming Intel handhelds" and controller support for MSI Claw devices, including last year's well-received Claw 8 AI Plus.
- YouTuber ETA Prime demoed a SteamOS 3.8 beta running on the MSI Claw 8 AI Plus, calling it "not perfect" but reporting that "everything works pretty well."
- Intel's Nick Mijuskovic said the company is working on Mesa drivers and collaborating with Valve, but had "nothing to share timeline-wise" on SteamOS support for Panther Lake and the G3 Extreme chip inside the Claw 8 EX AI Plus.
- Valve is also collaborating "very closely" with Nvidia and has "a growing team" dedicated to Nvidia drivers, though Griffais does not expect support to roll out this year.
- A Reddit user successfully booted SteamOS on an Intel Arc B580 desktop GPU, separate from the handheld work.
Why it matters: SteamOS is escaping its AMD-only roots: Intel handhelds already have a working beta, and Intel Arc B580 desktops can boot the OS, which means future non-AMD Steam Deck rivals could ship without Windows. Nvidia support is delayed past year-end and Intel won't commit to a Panther Lake date, so the AMD-powered Steam Deck keeps its exclusivity advantage for now while Valve builds out a multi-vendor SteamOS ecosystem.
