The Mound: Omen of Cthulhu on the Steam Machine
Can the Steam Machine run The Mound: Omen of Cthulhu?
Not yet known — The Mound: Omen of Cthulhu isn't out, so Valve hasn't rated it for SteamOS and there's nothing honest to derive a verdict from.
We'll publish one when it launches and Valve rates it. One signal does exist, and it isn't ours: 6 Linux players have reported running it under Proton, rating it Gold. That says it runs — not how fast. Recommended RAM is 16 GB — exactly the Machine's 16 GB.

Analysis — The Mound: Omen of Cthulhu on the Steam Machine
This kind of action game is GPU-bound on the Machine: the frame-rate follows resolution and post-processing. FSR is the main lever when frames get tight; effects and shadows go before textures.
The Mound: Omen of Cthulhu has no SteamOS rating yet. A similar game we do rate, Call of Cthulhu: The Wasted Land, lands green on the Steam Machine — a reasonable first guide until this one gets its own verdict.
Steam lists full controller support, so it plays from the sofa without a keyboard.
