Within the weeks since Valve’s Steam Deck launch, followers and critics alike have been poring by means of the machine’s potentialities, stymied partly by near-daily software and OS updates. I beforehand posited in my review that Steam Deck was not “completed,” and whereas the machine has turn out to be rather more secure, its full potential stays unclear.
Maybe that is why the newest Steam Deck evaluation from the {hardware} geniuses at Digital Foundry has struck gold. On Tuesday, website founder Richard Leadbetter unearthed one thing that the neighborhood at giant seems to have missed up till now: The moveable, 15 W-maximum Steam Deck is able to ray tracing.
The (R)DNA was in Steam Deck the entire time
The proof, as seen in a video on DF’s YouTube channel, required an overkill testing state of affairs. Leadbetter wiped the system’s default OS, put in Home windows 10, and retested ray tracing-compatible software program earlier than wiping the system once more to get SteamOS again on there. This obnoxious course of was required throughout Leadbetter’s testing interval as a result of Steam Deck doesn’t formally assist a dual-boot possibility for a number of OS installs, although fans have more recently come up with methods to try this.
The 4 video games in query (Quake II RTX, Control, Metro Exodus Enhanced Version, Doom Eternal) grey out their ray-tracing menu toggles when loaded through the default SteamOS implementation, which interprets Home windows variations of video games to Linux through the Proton compatibility layer. Those self same 4 video games, utilizing official Home windows 10 drivers from Valve and AMD, acknowledge the RDNA 2 cores constructed into Steam Deck’s customized APU and unlock each ray-tracing possibility—simply as if PC avid gamers have been utilizing a GPU from AMD’s latest RX 6000 collection.
Their ray-tracing implementations embody various quantities of dazzling results that take mild reflection and materials properties into consideration, sometimes leading to extra life like and grounded lighting and shadows. Unsurprisingly, all of the video games examined want visible downgrades to get near-stable 30 fps with ray-tracing options enabled, and these come principally within the type of pixel decision downgrades at roughly 540p.

On a pixel-count degree, that is on par with the blurry Change ports of Doom (2016) or The Witcher 3. However Leadbetter factors to Metro Exodus‘ implementation of temporal anti-aliasing upscaling (TAAU), which makes a pixel decision of 504p look extra crisp at Deck’s full 800p decision—and it seems to be even higher on Steam Deck’s 7-inch display than it does on an online browser. Quake II RTX is a specific stunner because of its reliance on a full path-tracing mannequin, versus any pre-baked lighting. Downscale it to a late-Nineties decision of 252p with full ray tracing enabled, and the Steam Deck can run the sport at one thing approaching 60 fps. Wow. (That is hilarious partly as a result of the ray-tracing mode in question was developed by Nvidia, although it is not an “RTX” {hardware} unique.)
TAAU has superior considerably as an possibility in video video games previously few years, proper alongside upscaling choices like Nvidia’s proprietary DLSS and AMD’s open supply FidelityFX Tremendous Decision (FSR). The latter already works on Deck in its 1.0 implementation, however FSR 2.0 sounds like it will take the best ideas from existing TAAU implementations and supercharge them upon its launch later this year on quite a lot of GPUs. AMD has but to announce particular Steam Deck plans for FSR 2.0, nevertheless it’s exhausting to think about that the Valve-AMD partnership shouldn’t be put to good use right here.
This week’s exams counsel that Steam Deck may match Xbox Sequence S’ ray-tracing outcomes.
All to say: Decrease base resolutions, smarter upscaling, and RDNA 2 silicon may make moveable, ray-traced gaming on Steam Deck a authentic possibility within the close to future, based mostly on Leadbetter’s exams. And as Leadbetter reminds viewers, shopping for a Steam Deck is a neater proposition if it does not really feel trapped in a “last-gen” 3D gaming universe.
We’re more likely to see extra video games emphasize RDNA 2-based ray-tracing results on AMD-powered consoles like Xbox Sequence X/S and PlayStation 5 in methods which might be essential to gameplay, slightly than simply cool lighting tweaks. If video games embody scaled-down ray-tracing results on the weaker Sequence S console, this week’s exams counsel that Steam Deck may match the outcomes—and that is already the case to some extent with Metro Exodus.
