Gabe, where's the 4K? For verification under Steam Machine, games must run even at 30 frames in 1080p
Steam Machine "Verified" status isn't picky about rock-solid 60 fps — it simply asks that a title can hit at least 30 fps at native 1080p. That's the bar.
Valve talked up 4K via FSR, which sounds nice on paper. The hitch: if a game is only validated at 1080p/30 fps, upscaling that source to 4K won't magically preserve 30 fps. The only practical way to stretch into 4K at playable frame‑rates is the "ultra performance" upscaler, which takes 720p up to 4K — and with FSR versions up to FSR 4, that often looks rough (yes, eye strain is a real possibility).
Want 60 fps? Then you’re looking at turning on generation (FG) — but generating frames from a 30 fps base introduces obvious artifacts because the input has too little temporal information. Trying FG from just 30 fps with DLSS or XeSS is, frankly, asking for visual glitches; there’s not enough data for clean interpolation.
One practical note: the 25,000+ games already marked "Verified" for Steam Deck carry that status over to Steam Machine automatically. So Valve can ship with a massive day‑one library — useful for launch optics, even if native, smooth 4K across that catalog is another problem.
