Valve's Steam Machine ships with SteamOS code still labeled for the Steam Deck, and reviewers are already finding it breaks games.
Gamers Nexus discovered numerous directories, system entries, and user profiles inside the Steam Machine's operating system that reference "deck." What looks like leftover development artifacts has real consequences: some games mistake the $1,049 living-room console for a handheld.
Kingdom Come: Deliverance 2 automatically disables mouse and keyboard support on first launch because it identifies the Steam Machine as a Steam Deck. The game assumes it's running on a portable device with gamepad-only controls and strips out PC input options, a problem that doesn't exist on the Steam Deck itself. Controllers can also "drop out" mid-game due to the same misidentification.
Valve has already pushed a fix: a per-game setting that disables automatic Steam Deck detection. The toggle lets titles bypass the handheld profile and recognize the Steam Machine as its own hardware configuration. But the patch is reactive, not preventive, it requires developers to opt in game by game.
The issue cuts to the core of Valve's strategy. The company has positioned SteamOS as a universal platform for everything from handhelds to living-room consoles to VR headsets.
The Steam Deck, the Steam Machine, and the Steam Frame were all supposed to run the same OS smooth. But the discovery shows SteamOS was architected with the Deck as the default target, and that assumption is baked into the system at a deep level.
The Steam Machine goes up for pre-order on June 29 through a lottery-style reservation system. It packs a custom AMD Zen 4 processor with RDNA 3 graphics, 16GB of DDR5 RAM plus 8GB of GDDR6 VRAM, and targets 4K gaming at 60fps with FSR upscaling.
Valve claims six times the horsepower of the Steam Deck. But raw specs don't fix software that thinks a console is a handheld. For a product delayed multiple times by the global memory shortage and finally landing at a premium price point, shipping with Deck-first code that breaks games is not the launch Valve wanted.
