Steam Deck, without a fake benchmark
The official note
Steam sells the game. A Deck compatibility badge was not part of the material verified for this page, and a sidebar has called the status unknown. Konami's 14 October 2026 known-issues note says some UI can render incompletely or run off the screen on Steam Deck. They listed it as under investigation. The 22 October patch notes that were read do not say this UI bug is fixed.
No frame rate, thermal limit, or graphics preset for LCD or OLED hardware is in those notes. A 'runs well' answer would be a guess. It is not printed.
What a real test would include
A useful follow-up is a timed session on both Deck models at the default, medium, and low presets, with the UI bug checked before and after. That session has not been run for this site. Until it is, the PC requirements are the closest spec, and they are desktop parts, not a Deck score.
What I ran into
I play on a Deck and I still would not type a frame number from memory. The only sentence I can stand behind is Konami's UI warning. The rest of the page is the absence of a test, labeled as an absence.
Questions
Does it run well on Steam Deck?
Not answered. Konami has confirmed a UI overflow and has not published performance figures.
Was the UI bug fixed on 22 October?
The patch notes read for that day do not list the Steam Deck UI issue as fixed. It remains the 14 October investigation item.
