Reasons for worry

In a recent interview with The Memory Core newsletter, GameSir admitted that its primary motivation for releasing a Windows emulation tool was to sell more of its controllers. But GameSir’s controllers aren’t required to use the Android version, which it says was sideloaded on 5 million (primarily Chinese) Android devices even before its official Google Play release in November.

GameHub on Android has also faced controversy for including a number of invasive trackers (which are removed in a community-built Lite version). A GameSir representative told The Memory Core that this was just standard practice in the Chinese market, where there is less sensitivity to such user tracking, and that it has since been removed.

The representative also addressed concerns about reusing open source compatibility code in that interview, saying that its Windows emulator was “developed in-house by GameSir’s core engineering team” with its “own in-house compatibility layer (such as syscall hooks, GameScopeVK, and other technologies), rather than modifications to Wine’s core code.” That said, the representative admitted GameFusion “reference[s] and use UI components from Winlator [an open source Windows emulation tool for Android]… to maintain ecosystem compatibility and familiarity.”

The compatibility issues and controversial corporate entity involved here probably mean that GameHub for Mac won’t be the Valve SteamOS/Proton moment that Apple gamers have been waiting for. Still, it’ll be nice for MacBook owners to have yet another option to play Windows games without needing to run a Windows install.

RAM shortage hits Valve’s four-year-old Steam Deck, now available “intermittently”

gaming, ram shortage, steam deck, steamos, Tech, valve / /

Earlier this month, Valve announced it was delaying the release of its new Steam Machine desktop and Steam Frame VR headset due to memory and storage shortages that have been cascading across the PC industry since late 2025. But those shortages are also coming for products that have already launched.

Valve had added a note to its Steam Deck page noting that the device would be “out-of-stock intermittently in some regions due to memory and storage shortages.” None of Valve’s three listed Steam Deck configurations are currently available to buy, nor are any of the certified refurbished Steam Deck configurations that Valve sometimes offers.

Valve hasn’t announced any price increases for the Deck, at least not yet—the 512GB OLED model is still listed at $549 and the 1TB version at $649. But the basic 256GB LCD model has been formally discontinued now that it has sold out, increasing the Deck’s de facto starting price from $399 to $549. Valve announced in December that it was ending production on the LCD version of the Deck and that it wouldn’t be restocked once it sold out.

The Steam Deck’s hardware is four years old this month, and faster hardware with better chips and higher-resolution screens have been released in the years since. But those Ryzen Z1 and Z2 chips aren’t always dramatically faster than the Deck’s semi-custom AMD chip; many of those handhelds are also considerably more expensive than the OLED Deck’s $549 starting price. When it’s in stock, the Deck still offers compelling performance and specs for the price.

Why $700 could be a “death sentence” for the Steam Machine

Bad news for Valve in particular?

On the surface, it might seem like every company making gaming hardware would be similarly affected by increasing component costs. In practice, though, analysts suggested that Valve might be in a uniquely bad position to absorb this ongoing market disruption.

Large console makers like Sony and Microsoft “can commit to tens of millions of orders, and have strong negotiating power,” Niko Partners analyst Daniel Ahmad pointed out. The Steam Machine, on the other hand, is “a niche product that cannot benefit in the same way when it comes to procurement,” meaning Valve has to shoulder higher component cost increases.

F-Squared’s Futter echoed that Valve is “not an enormous player in the hardware space, even with the Steam Deck’s success. So they likely don’t have the same kind of priority as a Nintendo, Sony, or Microsoft when it comes to suppliers.”

The size of the Steam Machine price adjustment also might depend on when Valve made its supply chain commitments. “It’s not clear when or if Valve locked in supply contracts for the Steam Machine, or if supply can be diverted from the Steam Deck for the new product,” Tech Insights analyst James Sanders noted. On the other hand, “Sony and Microsoft likely will have locked in more favorable component pricing before the current spike,” Van Dreunen said.

That said, some other aspects of the Steam Machine design could give Valve some greater pricing flexibility. Sanders noted that the Steam Machine’s smaller physical size could mean smaller packaging and reduced shipping costs for Valve. And selling the system primarily through direct sales via the web and Steam itself eliminates the usual retailer markups console makers have to take into account, he added.

“I think Valve was hoping for a much lower price and that the component issue would be short-term,” Cole said. “Obviously it is looking more like a long-term issue.”

SteamOS continues its slow spread across the PC gaming landscape

Over time, Valve sees that kind of support expanding to other Arm-based devices, too. “This is already fully open source, so you could download it and run SteamOS, now that we will be releasing SteamOS for Arm, you could have gaming on any Arm device,” Valve Engineer Jeremy Selan told PC Gamer in November. “This is the first one. We’re very excited about it.”

It’s an especially exciting prospect when you consider the wide range of Arm-based Android gaming handhelds that currently exist across the price and performance spectrum. While emulators like Fex can technically let players access Steam games on those kinds of handhelds, official Arm support for SteamOS could lead to a veritable Cambrian explosion of hardware options with native SteamOS support.

Valve seems aware of this potential, too. “There’s a lot of price points and power consumption points where Arm-based chipsets are doing a better job of serving the market,” Valve’s Pierre-Louis Griffais told The Verge last month. “When you get into lower power, anything lower than Steam Deck, I think you’ll find that there’s an Arm chip that maybe is competitive with x86 offerings in that segment. We’re pretty excited to be able to expand PC gaming to include all those options instead of being arbitrarily restricted to a subset of the market.”

That’s great news for fans of PC-based gaming handhelds, just as the announcement of Valve’s Steam Machine will provide a convenient option for SteamOS access on the living room TV. For desktop PC gamers, though, rigs sporting Nvidia GPUs might remain the final frontier for SteamOS in the foreseeable future. “With Nvidia, the integration of open-source drivers is still quite nascent,” Griffais told Frandroid about a year ago. “There’s still a lot of work to be done on that front… So it’s a bit complicated to say that we’re going to release this version when most people wouldn’t have a good experience.”

SteamOS vs. Windows on dedicated GPUs: It’s complicated, but Windows has an edge

AMD, AMD Ryzen, gaming, intel, NVIDIA, Radeon, steamos, Tech, Windows, Windows 11, windows 11 25h2 / /

Other results vary from game to game and from GPU to GPU. Borderlands 3, for example, performs quite a bit better on Windows than on SteamOS across all of our tested GPUs, sometimes by as much as 20 or 30 percent (with smaller gaps here and there). As a game from 2019 with no ray-tracing effects, it still runs serviceably on SteamOS across the board, but it was the game we tested that favored Windows the most consistently.

In both Forza Horizon 5 and Cyberpunk 2077, with ray-tracing effects enabled, you also see a consistent advantage for Windows across the 16GB dedicated GPUs, usually somewhere in the 15 to 20 percent range.

To Valve’s credit, there were also many games we tested where Windows and SteamOS performance was functionally tied. Cyberpunk without ray-tracing, Returnal when not hitting the 7600’s 8GB RAM limit, and Assassin’s Creed Valhalla were sometimes actually tied between Windows and SteamOS, or they differed by low-single-digit percentages that you could chalk up to the margin of error.

Now look at the results from the integrated GPUs, the Radeon 780M and RX 8060S. These are pretty different GPUs from one another—the 8060S has more than three times the compute units of the 780M, and it’s working with a higher-speed pool of soldered-down LPDDR5X-8000 rather than two poky DDR5-5600 SODIMMs.

But Borderlands aside, SteamOS actually did quite a bit better on these GPUs relative to Windows. In both Forza and Cyberpunk with ray-tracing enabled, SteamOS slightly beats Windows on the 780M, and mostly closes the performance gap on the 8060S. For the games where Windows and SteamOS essentially tied on the dedicated GPUs, SteamOS has a small but consistent lead over Windows in average frame rates.

Why won’t Steam Machine support HDMI 2.1? Digging in on the display standard drama.

AMD, drivers, gaming, steam, steam machine, steamos, valve, Windows / /

When Valve announced its upcoming Steam Machine hardware last month, some eagle-eyed gamers may have been surprised to see that the official spec sheet lists support for HDMI 2.0 output, rather than the updated, higher-bandwidth HDMI 2.1 standard introduced in 2017. Now, Valve tells Ars that, while the hardware itself actually supports HDMI 2.1, the company is struggling to offer full support for that standard due to Linux drivers that are “still a work-in-progress on the software side.”

As we noted last year, the HDMI Forum (which manages the official specifications for HDMI standards) has officially blocked any open source implementation of HDMI 2.1. That means the open source AMD drivers used by SteamOS can’t fully implement certain features that are specific to the updated output standard.

“At this time an open source HDMI 2.1 implementation is not possible without running afoul of the HDMI Forum requirements,” AMD engineer Alex Deucher said at the time.

Doing what they can

This situation has caused significant headaches for Valve, which tells Ars it has had to validate the Steam Machine’s HDMI 2.1 hardware via Windows during testing. And when it comes to HDMI performance via SteamOS, a Valve representative tells Ars that “we’ve been working on trying to unblock things there.”

That includes unblocking HDMI 2.0’s resolution and frame-rate limits, which max out at 60 Hz for a 4K output, according to the official standard. Valve tells Ars it has been able to increase that limit to the “4K @ 120Hz” listed on the Steam Machine spec sheet, though, thanks to a technique called chroma sub-sampling.

Testing shows why the Steam Machine’s 8GB of graphics RAM could be a problem

AMD, gaming, intel, NVIDIA, steam deck, steam machine, steamos, Tech / /

By Valve’s admission, its upcoming Steam Machine desktop isn’t swinging for the fences with its graphical performance. The specs promise decent 1080p-to-1440p performance in most games, with 4K occasionally reachable with assistance from FSR upscaling—about what you’d expect from a box with a modern midrange graphics card in it.

But there’s one spec that has caused some concern among Ars staffers and others with their eyes on the Steam Machine: The GPU comes with just 8GB of dedicated graphics RAM, an amount that is steadily becoming more of a bottleneck for midrange GPUs like AMD’s Radeon RX 7060 and 9060, or Nvidia’s GeForce RTX 4060 or 5060.

In our reviews of these GPUs, we’ve already run into some games where the RAM ceiling limits performance in Windows, especially at 1440p. But we’ve been doing more extensive testing of various GPUs with SteamOS, and we can confirm that in current betas, 8GB GPUs struggle even more on SteamOS than they do running the same games at the same settings in Windows 11.

The good news is that Valve is working on solutions, and having a stable platform like the Steam Machine to aim for should help improve things for other hardware with similar configurations. The bad news is there’s plenty of work left to do.

The numbers

We’ve tested an array of dedicated and integrated Radeon GPUs under SteamOS and Windows, and we’ll share more extensive results in another article soon (along with broader SteamOS-vs-Windows observations). But for our purposes here, the two GPUs that highlight the issues most effectively are the 8GB Radeon RX 7600 and the 16GB Radeon RX 7600 XT.

These dedicated GPUs have the benefit of being nearly identical to what Valve plans to ship in the Steam Machine—32 compute units (CUs) instead of Valve’s 28, but the same RDNA3 architecture. They’re also, most importantly for our purposes, pretty similar to each other—the same physical GPU die, just with slightly higher clock speeds and more RAM for the 7600 XT than for the regular 7600.

New project brings strong Linux compatibility to more classic Windows games

compatibility layer, gaming, Linux, Open Source, steamos, valve, Windows / /

Those additional options should be welcome news for fans looking for new ways to play PC games of a certain era. The PC Gaming Wiki lists over 400 titles written with the D3D7 APIs, and while most of those games were released between 2000 and 2004, a handful of new D3D7 games have continued to be released through 2022.

The D3D7 games list predictably includes a lot of licensed shovelware, but there are also well-remembered games like Escape from Monkey Island, Arx Fatalis, and the original Hitman: Codename 47. WinterSnowfall writes that the project was inspired by a desire to play games like Sacrifice and Disciples II on top of the existing dxvk framework.

Despite some known issues with certain D3D7 titles, WinterSnowfall writes that recent tuning means “things are now anywhere between decent to stellar in most of the supported games.” Still, the project author warns that the project will likely never reach full compatibility since “D3D7 is a land of highly cursed API interoperability.”

Don’t expect this project to expand to include support for even older DirectX APIs, either, WinterSnowfall warns. “D3D7 is enough of a challenge and a mess as it is,” the author writes. “The further we stray from D3D9, the further we stray from the divine.”

Microsoft and Asus’ answers to SteamOS and the Steam Deck launch on October 16

ASUS, asus rog ally, gaming, microsoft, steamos, Tech, Windows 11, xbox, xbox rog ally / /

Asus and Microsoft will be launching their ROG Xbox Ally series of handheld gaming PCs starting October 16, according to an Asus announcement that went out today.

An Xbox-branded extension of Asus’ existing ROG Ally handheld line, the basic ROG Xbox Ally and more powerful ROG Xbox Ally X, both run a version of Windows 11 Home that’s been redesigned with a controller-first Xbox-style user interface. The idea is to preserve the wide game compatibility of Windows—and the wide compatibility with multiple storefronts, including Microsoft’s own, Valve’s Steam, the Epic Games Store, and more—while turning off all of the extra Windows desktop stuff and saving system resources. (This also means that, despite the Xbox branding, these handhelds play Windows PC games and not the Xbox versions.)

Microsoft and Asus initially announced the handhelds in June. Microsoft still isn’t sharing pricing information for either console, so it’s hard to say how their specs and features will stack up against the Steam Deck (starting at $399 for the LCD version, $549 for OLED), Nintendo’s Switch 2 ($450), or past Asus handhelds like the ROG Ally X ($800).

Both consoles share a 7-inch, 1080p IPS display with a 120 Hz refresh rate, Wi-Fi 6E, and Bluetooth 5.4 support, but their internals are quite a bit different. The lower-end Xbox Ally uses an AMD Ryzen Z2 A chip with a 4-core Zen 2-based CPU, an eight-core RDNA2-based GPU, 512GB of storage, and 16GB of LPDDR5X-6400—specs nearly identical to Valve’s 3-year-old Steam Deck. The Xbox Ally X includes a more interesting Ryzen AI Z2 Extreme with an 8-core Zen 5 CPU, a 16-core RDNA3.5 GPU, 1TB of storage, 24GB of LPDDR5X-8000, and a built-in neural processing unit (NPU).

The beefier hardware comes with a bigger battery—80 WHr in the Ally X, compared to 60 WHr in the regular Ally—and that also makes the Ally X around a tenth of a pound (or 45 grams) heavier than the Ally.

On the PC side, though, Microsoft is still a force to be reckoned with. Practically every desktop or laptop gaming PC runs Windows by default, despite half-hearted efforts by Apple to turn MacOS into a serious gaming platform. And while Valve’s Linux-based SteamOS has created a significant handheld gaming PC niche—and is hinting at attempts to push into the gaming desktop space—it does so only through a Proton compatibility layer built on top of the strong developer interest in Windows gaming.

Microsoft is already highlighting its software advantage over SteamOS, promoting the Xbox Experience for Handhelds’ “aggregated game library” that can provide “access to games you can’t get elsewhere” through multiple Windows-based game launchers. There’s no reason to think that living room console players wouldn’t also be interested in that kind of no-compromise access to the full suite of Windows gaming options.

Microsoft has been preparing the Xbox brand for this ultimate merger between PC and console gaming for years, too. While the name “Xbox” was once synonymous with Microsoft’s console gaming efforts, that hasn’t been true since the launch of “Xbox on Windows 10” in 2015 and the subsequent Windows Xbox app.

Meanwhile, offerings like Microsoft’s “Play Anywhere” initiative and the Xbox Game Pass for PC have gotten players used to purchases and subscriptions giving them access to games on both Xbox consoles and Windows PCs (not to mention cloud streaming to devices like smartphones). If your living room Xbox console simply played Windows games directly (along with your Windows-based handheld gaming PC), this sort of “Play Anywhere” promise becomes that much simpler to pull off without any need for porting effort from developers.

These are the kinds of thoughts that ran through my mind when I heard Bond say yesterday that Xbox is “working closely with the Windows team to ensure that Windows is the number one platform for gaming” while “building you a gaming platform that’s always with you so you can play the games you want across devices anywhere you want, delivering you an Xbox experience not locked to a single store or tied to one device.” That could simply be the kind of cross-market pablum we’re used to hearing from Microsoft. Or it could be a hint of a new world where Microsoft finally fully leverages its Windows gaming dominance into a new vision for a living room Xbox console.

SteamOS 3.7 brings Valve’s gaming OS to other handhelds and generic AMD PCs

asus rog ally, asus rog ally x, gaming, lenovo legion go, steam deck, steamos, Tech, valve / /

Valve’s instructions will walk you through downloading a SteamOS recovery image and copying it to a USB drive using either the Rufus tool (on Windows) or Balena Etcher (the preferred macOS and Linux utility). After turning Secure Boot off, you should be able to boot from the USB drive and install SteamOS as you would on a regular Steam Deck.

Note that there’s no simple, officially supported way to dual-boot SteamOS and Windows; if you decide to turn your handheld, laptop, or desktop into a new Steam Machine, the only way to make it back into a Windows PC is to re-enable Secure Boot and install a fresh copy from another USB drive.

The SteamOS 3.7 update (officially, version 3.7.8) also includes a bunch of other updates to the underlying software: version 6.11 of the Linux kernel (up from version 6.5 in SteamOS 3.6), “a newer Arch Linux base,” version 6.2.5 of the Plasma interface in desktop mode, new Mesa graphics drivers, and various other tweaks and bug fixes.

A second act for SteamOS

The original version of SteamOS was designed to be widely compatible with all kinds of PC hardware and was available both from major PC manufacturers and as a standalone OS that you could (and which we did) install on custom, self-built PCs. But these computers and that version of SteamOS mostly flopped, at least in part because they only ran a small subset of games that natively supported Linux.

The current version of SteamOS launched with more modest aims as the first-party operating system for a single piece of hardware. But by focusing on the game compatibility problem first and leading the way with category-defining hardware, Valve has actually built a much stronger foundation for the current version of SteamOS than it did for the original.

That doesn’t make SteamOS a drop-in replacement for Windows—without strong support for Intel or Nvidia hardware, it’s not a great candidate for the majority of gaming PCs, or even Intel-powered gaming handhelds like the MSI Claw A1M. And Windows is set up to be a multipurpose general-use operating system in ways that SteamOS isn’t; Valve still says that, despite the presence of desktop mode, “users should not consider SteamOS as a replacement for their desktop operating system.” But for certain kinds of systems that are primarily used as gaming PCs, SteamOS is a real contender.

Bye-bye Windows gaming? SteamOS officially expands past the Steam Deck.

gaming, steamos, valve / /

Almost exactly a year ago, we were publicly yearning for the day when more portable gaming PC makers could ditch Windows in favor of SteamOS (without having to resort to touchy unofficial workarounds). Now, that day has finally come, with Lenovo announcing the upcoming Legion Go S as the first non-Valve handheld to come with an officially licensed copy of SteamOS preinstalled. And Valve promises that it will soon ship a beta version of SteamOS for users to “download and test themselves.”

As Lenovo’s slightly downsized followup to 2023’s massive Legion Go, the Legion Go S won’t feature the detachable controllers of its predecessor. But the new PC gaming handheld will come in two distinct versions, one with the now-standard Windows 11 installation and another edition that’s the first to sport the (recently leaked) “Powered by SteamOS” branding.

The lack of a Windows license seems to contribute to a lower starting cost for the “Powered by SteamOS” edition of the Legion Go S, which will start at $500 when it’s made available in May. Lenovo says the Windows edition of the device—available starting this month—will start at $730, with “additional configurations” available in May starting as low as $600.

Both the Windows and SteamOS versions of the Legion Go S will weigh in at 1.61 lbs with an 8-inch 1200p 120 Hz LCD screen, up to 32GB of RAM, and either AMD’s new Ryzen Z2 Go chipset or an older Z1 core.

Watch out, Windows?

Valve said in a blog post on Tuesday that the Legion Go S will sport the same version of SteamOS currently found on the Steam Deck. The company’s work getting SteamOS onto the Legion Go S will also “improve compatibility with other handhelds,” Valve said, and the company “is working on SteamOS support for more devices in the future.”
