While working on our review of Doom: The Dark Ages last week, I was unable to test the game on the Steam Deck due to a bug that prevented it from launching on SteamOS. I didn’t consider this much of a loss at the time, since I figured the Deck’s 3-year-old portable hardware was rated way below the minimum PC specs for the game, which call for ray tracing-capable graphics cards at a minimum.
Over the weekend, though, Valve released a preview build of a new version of SteamOS that allows Doom: The Dark Ages to actually launch on the Steam Deck. And after a bit of testing, I found the game is surprisingly playable on Valve’s portable hardware, provided you’re prepared to turn down the graphics settings.
With all the graphical quality sliders set to “Low” (and FSR upscaling set to “Performance”), I was able to run Doom: The Dark Ages at the system’s native 1280×800 resolution and a reasonably steady 30 to 40 fps.
