The Steam Deck Can Run Portal 2 In 4K/60FPS

Steam Decks are arriving across the country starting this month. If you live in the Seattle area you might have received yours a bit early thanks to a certain CEO, while the rest of us will have to wait for regular shipping time. But while we wait, we can at least become that much more excited about Valve’s handheld PC by seeing what others can do with it.

Forbes’ Jason Evangelho was apparently able to get his Deck to run Portal 2 at 4K and a “mostly stable” 60 fps.

You can see the first few minutes of Evangelho’s playthrough on the Linux for Everyone YouTube channel. The Steam Deck’s operating system is actually a modified version of Proton, which is, in turn, a Linux-based OS. All graphics settings are set to “high,” anti-aliasing is disabled, and filtering is set to anisotropic 4x.

What’s most surprising beyond the fact that the Deck’s humble AMD-sourced hardware can run a game at 4K at all is the fact that Portal 2 is running without AMD FidelityFX Super Resolution enabled. The Steam Deck natively supports AMD’s up-resolution technology that’s built into its SteamOS so that any game can have AMD FSR even if it’s not supported by the game itself.

Portal 2 does look a bit dated at 4K, but it’s still a great game that will play great on the Deck thanks to being verified several months ago (and Portal 1 even got a new UI for the Deck).

If you want a brand-new Portal experience, then you should get your hands on Aperture Desk Job. Although Valve goes out of its way to inform you that
