Yes, it runs on a Steam Deck, but it is not a smooth experience and Valve has not rated it. As observed on 2026-10-30, the Steam hardware-compatibility record for app 4115450 carries no rating at all — no Playable and no Verified — so the status is untested by Valve rather than a measured refusal. Steam Deck HQ's hands-on test on lowest graphics averaged roughly 23 to 27 FPS in the Crimson Forest and dipped as low as 10 FPS, with roughly 2 to 2.5 hours of battery at 21 to 25 W.
Two things follow from that. It is playable for slow, deliberate play, but this is a parry timing game and the input lag matters more than the frame count. And both the rating and the frame rates can move with a patch, so treat everything below as observed on 2026-10-30 and due for re-check.
The exact settings the test used
Reproduce the measurement with these, in this order:
| Setting | Value |
|---|---|
| Graphics preset | Lowest |
| Upscaler | FSR Performance |
| Frame rate cap | 30 FPS |
| Refresh rate | 90 Hz |
| TDP limit | None |
| GPU clocks | Disabled |
| Linear scaling | Off |
| Half-rate shading | Off |
The 30 FPS cap is what keeps the frame time stable — without it the Deck decides between dropping frames and holding a higher rate, and a parry window is the last place you want that trade. The full desktop settings ladder is on the PC performance page, and the buttons you will be remapping are on the controls page.
Frame generation is the setting to leave off
Turning on frame generation through MAKO, or lossless scaling, adds very noticeable input lag. In a game where a parry is a timing window measured in frames, that lag is not a trade you can make — it is why the frame rate does not recover on its own. HelixSR and FSR 4 were also tried and did not help.
If you take one thing from this page, take that one: the fix is lower settings, not a smoother frame generator. The parry guide has the timing window the whole game is built on, and the DLSS page covers what the 4.5 suite does on a desktop RTX card.
What S-GAME says about weaker hardware
The developer's launch letter says the rasterized visuals were refined so ray tracing can be turned off on mid-range and lower-end hardware. On a Deck that means the ray-tracing switch stays off from the start rather than being traded away later. S-GAME also says they want the game to run on Deck, so the handheld is on their list rather than something they are ignoring.
If you want it smooth now, the realistic routes are
- GeForce NOW — stream the game from a capable PC, where the hardware does the work and the Deck is a thin client.
- Steam Remote Play — the same idea from a desktop you own.
- A newer handheld — an ROG Ally or similar gives you more GPU headroom than the Deck's fixed APU.
None of those is the game running natively on Deck. If you specifically want to run it on Deck hardware, the settings table above is the honest answer.
Re-check this page
The compatibility rating and the measured frame rates are window content. They were observed on 2026-10-30, and a patch can move either one, so re-read this page and the Steam store listing before you plan around a number.
