The store's compatibility data cites unsupported graphics performance. SteamOS has a separate Playable result with setup and controller caveats, but that does not override the handheld's Unsupported badge.
Official reason: graphics performance
Separate result with first-run internet and external-controller caveats
What the Steam result means
Valve's current store data resolves the Steam Deck category as Unsupported and lists graphics performance as the failed check. That is a stronger signal than a user saying the executable opened once: it means buyers should not expect the game to meet Valve's current Deck compatibility target.
Compatibility labels can change after game patches, Proton updates or a new Valve review. Use the live Steam badge as the final answer at purchase time. This page records the status and reason observed on July 13, 2026 rather than presenting it as permanent.
Steam Deck and SteamOS are not the same result
| Environment | Current category | Published detail |
|---|---|---|
| Steam Deck | Unsupported | Graphics performance is the listed failure. |
| SteamOS | Playable | The game starts, but first-time setup needs an active internet connection and Steam lists an external-controller limitation for the primary player. |
| Windows PC | Officially supported platform | Requires a 64-bit Windows 11 system and an SSD under the published requirements. |
A desktop running SteamOS can have more power than a Steam Deck, so its result does not guarantee acceptable handheld performance. Likewise, community launch reports are useful troubleshooting clues but do not convert the official Deck category into Playable.
Should you buy it for Steam Deck?
Not if the Deck is your only intended machine. The current label gives you no reliable basis to expect stable performance throughout combat-heavy areas. If you also own a supported Windows PC, the safer approach is to test the free Steam demo there and treat any Deck experiment as optional rather than the purchase reason.
If you still test it, keep Steam's refund conditions in mind, avoid spending the entire test window in character creation, and reach a representative field encounter. A launcher opening or an empty room running smoothly is not enough to judge later quests.
What to recheck after an update
- Open the live Steam compatibility panel and look for a category change.
- Read the reason list rather than relying only on the badge color.
- Check the latest game patch notes for graphics, shader or performance changes.
- Test a combat-heavy area with the same power and frame-rate settings you plan to use.
- Separate SteamOS desktop reports from actual Steam Deck results.
Steam Deck FAQ
Does the demo have a different Deck rating?
The separate demo download does not establish compatibility for the full campaign. Use it for a local test, but follow the full game's live Steam Deck panel for the purchase decision.
Will lowering settings guarantee it works?
No. Lower settings may improve an individual scene, but the current official result remains Unsupported for graphics performance. Only sustained testing or a later compatibility update can answer whether a particular workaround is reliable.
Is PS5 a safer handheld alternative?
PS5 is not handheld, but it is a supported fixed console target. If portability is not essential, compare the PS5 specifications and solo format instead of buying the PC version solely for Deck use.
