Valve has detailed its verification requirements for each the Steam Machine PC gaming system and the Steam Frame wireless VR headset. Guidance to game developers for the Steam Machine may be very just like that provided for the Steam Deck and, for probably the most part, has only a couple of differences. For starters, any game that already meets Steam Deck verification is robotically verified for the Steam Machine. Per Vavle, this implies there’ll already be over 25,000 games able to run on the brand new gaming system. Nevertheless, the reverse won’t necessarily be true for the reason that Steam Machine could have more powerful hardware, so it stands to reason that a game which could also be verified for it may not be for the gaming handheld, but Valve has added a suggestion to developers that “Optimizing for lower spec machines expands your audience.”
That being said, Valve is asking developers to focus on 1080p 30 FPS because the goal so as to meet verification requirements for the Steam Machine. This is unquestionably a lower-end spec for PC gamers, however it could allow the custom AMD APU to more efficiently reach 4K via upscaling technology. Other general guidance includes providing support for various aspect ratios, something the PC community often hopes for with various ultrawide ratios corresponding to 21:9, 32:9, and 16:10 for gaming laptops. Not saving graphic settings to the cloud is one other, while conversely, offline support needs to be included. Multiple controller support can also be being requested, even when a game is single player, and if a title specifically only supports keyboard and mouse, it’ll only be verified for the Steam Machine.
Regarding the Steam Frame wireless VR headset, Valve has laid out its verified requirements, showing modest performance needs for its ARM-based processor. Support for x86 gaming is once more provided via Steam’s Proton integration, and there are not any verification requirements for streaming from PC to the Steam Frame via its USB dongle. Nevertheless, for standalone play, games should be compatible with the Steam Frame’s controllers and in a position to reach as much as 90 FPS for VR-designed games and 30 FPS for 2D titles. Developers must also ensure an optimized UI focused on legibility.
- No verified program for streaming
- If it runs well in your host PC, it’ll run well on Steam Frame
- Streaming requires no special integration, including for VR titles
Another items being asked of developers in relation to Proton Integration are to avoid using invasive DRM or anti-tamper solutions. Valve adds that it has its own built-in support for a lot of mainstream solutions, but acknowledges there are still challenges for custom integrations. Valve also stated that the Legion Go S and Legion Go 2 are currently in a SteamOS compatibility phase, which indicates potential greater adoption of its OS. There’s still no release date for either the Steam Machine or Frame, nor pricing, but we may very well be getting closer to an official announcement. More information for the above might be present in Valve’s GDC 2026 official slide deck here.
