Valve today (12 November 2025) announced their new Steam Machine (x86 CPU, 6x more powerful than Steam Deck) and Steam Frame (self-contained and PCVR streaming VR headset with ARM CPU & “FEX” translation of x86 to ARM) to be released in early 2026. No prices yet.
I’m trying to speculate what effects this will have on the wider Linux ecosystem. Both devices will be running Steam OS and be open so you can run any OS.
First, I’ve read many people state that the Steam Deck considerably increased the number of devices running Linux, so it seems to me that these two new devices will accelerate that trend.
Second, it seems to me that the Steam Frame will significantly increase VR use and development for Linux.
Third, I wonder what the implications of Frame’s x86 to arm translation layer (based on FEX, an open source project that I only learned about today) as well as Android compatibility (they state it can sideload Android APKs) will be. Could this somehow help either Linux on Apple silicon or Linux phone efforts? I’m very unfamiliar with what’s going on with either of these efforts, so I may be way out on a limb here.
What do you think about all this?
Edit: this article may prompt some additional thoughts with its discussion of the openness of the Frame - https://www.uploadvr.com/valve-steam-frame-catalog-whole-compatible/
Well it’s not going to suddenly be all VR’d up or anything 🤣
Part of the reason I would imaging they implementing a new kind of steam-input layer for VR is for things like a theater mode and desktop. I could see them making some sort of a simple hook for view controls in games for your exact scenario, but that would be heavily dependent on the game having something like free look already be possible, and then the developers just write a quick patch of a couple lines to hook the steam-vr-input hook into their code, and BAM.
I’m just wondering about basic functionality - can it play through without a crash or is it still Windows only for a smooth UX?
99% of all Windows games running Proton, and most perform better than on Windows, depending othe game.
For the specific games you mentioned, they all have Platinum rating in Proton, meaning flawless. You can see here in ProtonDB.
I’m not sure what your experience was in the past, but I write tons of Proton patches for games, and the only ones I’ve seen that don’t play well are the pre-DirectX9 games, which can’t plan on Windows XP or later anyway. Proton will soon be able to play these games without issue thanks to some Vulkan patches coming up.
