Valve has not published a Steam Deck compatibility rating for Gears of War: E-Day. The compatibility report Valve returns for the game sits in the Unknown category, with no test results attached and no accompanying note.
That is an absence rather than a verdict. The shooter entered Early Access on October 1, 2026 and launches worldwide on October 6, so a grade could still land.
Still, the requirements Xbox Game Studios publishes on the game's own Steam page describe a machine that looks very little like a Steam Deck.
What Valve's rating categories mean
Valve sorts games into four buckets. Verified means a game "passes all compatibility checks", with no configuration work required. Playable means a game "functions on Deck/Machine, but may require manual work from the user".
Unsupported means a game "does not function on this device due to incompatibility with Proton or specific hardware components". Digital Citizen covered what the middle grade looks like in practice when Dragon Age Inquisition moved into Playable.
Unknown is the fourth. Valve defines it as a game that "has not completed the compatibility review process", and adds that information about how it will play is unavailable. For comparison, Gears of War: Reloaded is rated Verified, and Valve lists the individual checks it passed. E-Day has none of that.
The minimum specification on the game's own Steam page
The minimum tier asks for Windows 10 64-bit, a Ryzen 5 2600X or Core i5-10400 class processor, and 12 GB of RAM. The graphics line is the unusual part.
It opens with "Hardware Ray Tracing capable GPU is required", then names the GeForce RTX 5050, the RTX 2060, the Radeon RX 6600 and the Radeon RX 9060. Storage is 115 GB, and the notes add "SSD required (solid-state drive)".
Digital Citizen has already gone through the launch timing and the full requirement list, and separately through what the 115 GB install does to console storage.
Where the Steam Deck sits against that list
| Minimum requirement | Steam Deck, per Valve |
|---|---|
| Windows 10 64-bit | SteamOS 3 (Arch-based) |
| 12 GB RAM | 16 GB LPDDR5 shared with the GPU |
| Hardware ray tracing capable GPU | 8 RDNA 2 CUs, 1.6GHz, 1.6 TFlops FP32 |
| 115 GB on an SSD | 64GB, 256GB or 512GB models |
The storage line is the bluntest of them. Valve still lists a 64 GB Steam Deck, and a 115 GB install does not fit on it.
The operating system line matters as well. Steam marks the game as Windows only, with no Linux build listed, so running it on SteamOS means running it through Proton.
Valve does not mention ray tracing anywhere in its published Steam Deck specifications. Whether the handheld satisfies that particular line is therefore not something either company has stated.
The Windows handhelds clear lines the Deck does not
ASUS lists the ROG Xbox Ally with a Ryzen Z2 A, 16 GB of LPDDR5 and a 512 GB NVMe SSD, running Windows 11 Home. The Ally X moves up to a Ryzen AI Z2 Extreme, 24 GB of LPDDR5X and a 1 TB SSD on the same operating system.
On paper, both clear the operating system requirement, the SSD requirement and the 12 GB memory floor. ASUS does not publish compute unit counts for either Radeon integrated GPU, so the ray tracing question stays open there too.
That gap is narrower than it sounds, and Digital Citizen has looked at how the Ally now compares with the Deck on price.
What is still not published
Valve has not rated the game for Steam Machine or Steam Frame either. Both come back Unknown from the same compatibility report.
The Steam page publishes only two tiers, minimum and recommended, and attaches no resolution or frame rate figure to either one. The single performance target Xbox has stated is 4K at up to 60FPS across campaign and multiplayer, which is a desktop claim rather than a handheld one.
The 115 GB figure is the install size at launch, and Xbox notes that future updates may require additional storage. Valve's own specification page carries the standard line that product specifications are subject to change, and a compatibility rating can appear at any point after release.
