The PC version of Dementium II is Dementium II HD, available on Steam. Its published requirements are modest by modern PC standards, but they are legacy specifications—not a guarantee of performance on a particular current PC. Steam lists controller support; the store page does not provide a Steam Deck compatibility rating or test result.

Can your PC run Dementium II?
Compare your system with the minimum column to check whether it meets the game’s posted baseline; the recommended column gives Steam’s higher listed target. The store specifications do not establish a frame rate, resolution, graphics preset, or how the game performs on modern integrated graphics. Meeting a listed requirement should not be read as a performance guarantee.

Windows requirements versus Steam support
The game listing still names Windows XP, Vista, and 7 as minimum operating systems, but that is separate from whether the current Steam client supports an older Windows installation. Steam’s listing says: “Starting January 1st, 2024, the Steam Client will only support Windows 10 and later versions.” Steam store page
In practical terms, the game’s legacy requirement does not mean you can rely on the current Steam client working on those older versions. For a Steam installation, account for Steam’s stated Windows 10-or-later client requirement.
Does Dementium II HD work on Steam Deck?
The Steam page confirms controller support, but it does not provide a Steam Deck compatibility rating or a Deck test result. Controller support alone does not establish that the game is rated Verified or Playable, or that it works correctly on a Deck. Steam store page

Accordingly, Deck compatibility is unverified by the available official store information. No performance or usability conclusion for the Deck can be drawn from the PC requirements or controller-support label.
