Phoronix reports: Steam on Linux use in March hit an all-time high of around 5.33% marketshare. Since then it pulled back to around 4% while for September 2026 the Steam Survey results... indicate a rather steep decline of 0.85%, down to 3.05%. Meanwhile macOS is at 1.92% and Microsoft Windows at 95%... Steam's Survey reports a 7.42% increase in Chinese use, up to 31.39% overall of the Steam population. Usually those large month-over-month swings where Steam China use shoots up dramatically is a boost to Windows and a detriment to Linux. Some attribute the large increases in Simplified Chinese use to being a reporting/sampling issue.

When diving into the Steam Linux data exclusively, CachyOS has spiked by another 2.65% to now account for 18.12% of the sampled Linux gaming population. That even outperforms SteamOS Holo coming in at 17.37%. Among Linux gamers on Steam, AMD CPUs still account for the high 60 percentage space thanks to the Steam Deck and Steam Machine using AMD APUs and their open-source/Linux support being popular with enthusiasts.

An anonymous reader quotes a report from Ars Technica: Rendering Doom in a database is obviously a bad idea," Lukas Vogel writes in a lengthy blog post explaining how exactly he managed to render Doom using an SQL database. OK, that's not entirely accurate. The SQLDoom project uses a small Python client to handle input and output, drive the game's timing, and display each frame to the screen. Behind that, a series of CedarDB tables tracks the game geometry and state, while about 1,300 lines of SQL queries spread across 89 common table expressions implement the game logic and generate 35 bitmap framebuffers per second.

In this, SQLDoom is a major improvement over Vogel's previous DoomQL project, which last year set out to build "a multiplayer Doom-like shooter entirely in SQL." Unfortunately, that effort ended up with raycasting-based, grayscale ASCII graphics that were more akin to the simplistic 90-degree-angled maps of Wolfenstein 3D. The newer SQLDoom, on the other hand, generates full-color 640x480 frames that look like they could have come from the original Doom executable. [...] If you want to run a Doomtabase on your own local machine, you can do so simply with the GitHub code, a copy of CedarDB, and a Doom WAD file. Or you can jump into a free online hosted demo match to test it out without all the setup [...].

Researchers from Carnegie Mellon, MIT, NYU, and Stanford have built an AI called Ataraxos that finally cracked Stratego, beating four-time world champion Pim Niemeijer 15 games to one with four draws. Its key advantage was a second neural network that estimates the identities of hidden enemy pieces, letting the system search plausible game states rather than brute-force a massive hidden-information space. Ars Technica reports: Just like [DeepMind's DeepNash, introduced in 2022], Ataraxos learned by playing against itself -- 163 million games in total. In these self-play sessions, moves that led to wins were reinforced and played more often in future matches, while moves that led to losses were played less, which was the same simple training idea. The difference was in how much Ataraxos adjusted after each game, because hidden information tends to send self-play learning algorithms around in circles. The team addressed this by making big, bold changes in strategy early in training and small, careful ones later.

The even bigger innovation was something DeepNash never had: thinking ahead before each move. AIs like AlphaGo refine their general strategy with a search just before acting. DeepMind couldn't make that work in Stratego because the search space was too large, leaving it an open question whether it was worth trying. "This is one of the things that we did figure out how to do," Farina said. The solution was a second neural network, a belief model, trained to guess the opponent's hidden pieces based on how they had been moving. This way, instead of iterating through every possible arrangement, Ataraxos samples plausible ones, plays out candidate moves in each, and picks based on how they turned out. And it shows in its playstyle.

[...] DeepNash was trained for two to three months on 1,024 of Google's specialized chips, a run the Ataraxos team estimates would cost $3 million to $4.5 million at 2025 prices. Ataraxos, in contrast, needed 16 GPUs for a week, plus an additional four GPUs for four days to train the belief model. Farina and lead author Samuel Sokota achieved this efficiency by writing a simulator that runs millions of moves per second on graphics cards. "At the scale that we are in academia, we don't really have access to an entire field of GPUs," Farina said. The algorithm also learned far faster -- it played about 34 times fewer games than DeepNash, and still ended up much stronger. The findings have been published in the journal Nature.

AmiMoJo shares a report from heise online: Anyone buying used hardware for a gaming PC needs to be careful: not just whether the components are still in order but also what the previous owner did with them. A case on Reddit shows this. Someone installed a used AMD processor, a Ryzen 7 5800X3D, in their PC. Because the previous owner was caught cheating, the new owner cannot start several online games.

The problem was noticed in the first-person shooter "Valorant" from the development studio Riot. Right from the first start, the new owner was kicked out directly, according to their statement. Riot support confirmed that the previous owner had cheated. The processor is therefore on an internal blacklist -- and, with its installation in the PC, now apparently also some other components like the mainboard. Riot support does not remove such entries manually.

In addition to "Valorant," all other PC games from Riot are affected: the strategy game "League of Legends," the auto-battler "Teamfight Tactics," the card game "Legends of Runeterra," the fighting game "2XKO," and likely future titles as well. Riot's "Vanguard" anti-cheat system traditionally runs deep in the Windows kernel and starts with the PC, but a June 2026 update allows it to launch with a game if security features such as TPM and Secure Boot are enabled.

It's unclear how Riot uniquely identifies processors, though possibilities include hardware fingerprinting based on chip behavior or storing identification hashes in the Trusted Platform Module (TPM), which Vanguard accesses in the newer mode.

An anonymous reader quotes a report from Ars Technica: For a long time, PC gamers could access many PlayStation 5 games only if the publisher invested in a bespoke port (something Sony has recently said it will be scaling back). Now, though, rapid advancements in PS5 emulators and other tools are making recent PlayStation titles increasingly playable on generic PCs. SharpEmu was the first of these emulators, advancing from a "very early alpha stage" in May to a current state that can "load the eboot.bin of real games, execute native CPU instructions, and partially handle GPU-related functionality." The most recent release boasts 10 tested games that reach a "playable" state, including six that developer CursedIfElse says are "fully playable at 60 fps." That includes simple 2D games like Tetris Forever but also 3D titles like Astro Bot and the PS5 Demon's Souls remaster running at playable frame rates.

[...] Amid that SharpEmu progress, fellow PS5 emulator KytyPS5 launched its first public version last week. The major expansion of PS4-focused emulator Kyty "can boot 2D games and a selection of 3D games, including titles built with Unreal Engine 4/5, Unity, and custom engines," according to its GitHub page. An extensive compatibility list for KytyPS5 already shows 134 titles with "controllable gameplay" on the new emulator, though many of those still include reports of persistent, game-breaking bugs. But you can already find YouTube footage of PS5 titles like Astro's Playroom and Demon's Souls running quite capably under the emulator.

On top of those more traditional emulators, AnyPS5 might be the most interesting effort to get PS5 games running on PC. The self-described "tool for automatic executables porting" works kind of like Apple's Game Porting Toolkit, relinking a PS5 game's original x86 game code directly to native executable instructions that can run on PC. That puts the effort somewhere between direct static decompilation of a game's source code and more complete emulation of the entire PS5 environment.

Xbox CEO Asha Sharma says Microsoft has no plans to sell the gaming business, telling The New York Times that "Xbox is not for sale" and that the company intends to take a long-term view. Windows Central reports: Microsoft's vast layoffs across the summer have hit Xbox in their thousands, with studios like Ninja Theory on the path to being closed, and others like Double Fine being divested completely. Microsoft has effectively shut down Halo Studios itself and handed off the franchise to Call of Duty showrunners instead, as Xbox aggressively seeks to restructure for its next decade.

[...] The NYT interviewed (paywall) Sharma recently covering the Xbox layoffs generally. The outlet said that Asha "did not stall" in declaring Xbox not-for-sale. "Xbox is not for sale. [...] We will do whatever it takes to set the company up for success, and we will look at the right partnerships, the right operating model and everything needed to achieve that. [...] We've got a long way to go with Microsoft and we're going to take the long-term view."

The NYT quite patronizingly called the comment a "bob and weave" seemingly unwilling to let go of the idea of divestiture. It's great shareholder bait; Xbox has long been an aspirational type of product, and it has been a loss leader in some regards. Microsoft CEO Satya Nadella has remarked in the past about how, despite the fact Xbox isn't a huge profit generator, fandom of the brand has led to lucrative deals for Azure on the business side of things. Yet, shareholders would love nothing more than for Microsoft to quit the difficult and risky game industry to dive all-in on AI psychosis products instead...

"In April this year, we saw Andy Nguyen turning the PS5 into a Linux-powered gaming PC," writes the blog It's FOSS.

It ran Steam games and emulators using the PS5's on-board hardware. But this week Andy announced he's "stopping all my work on PS5 Linux" and "stepping away from the PS5 scene." stopping work on porting the project to the PS5 Pro, which would've shipped sometime in 2027. Andy Nguyen: After pouring my heart and months of my life into it, including plans to finish PS5 Pro support and release in 2027, it's all down the sink.

The scene used to be a group of highly talented researchers, but now it is just a bunch of noobs using LLMs and writing hacks they don't even understand. Slop kiddies found the only hypervisor bug left, which I had also found a while ago, and decided to report to Sony. I asked them to at least wait for GTA 6 to come out so that people would have the opportunity to legally purchase the game and also enjoy Linux. They agreed to wait, but not a day passed and they decided to waste it instead.
Or, as It's FOSS tells it: Running Linux on a PlayStation console is possible because the PS5 Linux project was able to find a way past the hypervisor using exploits Sony had already patched, covering firmware 3.00 through 7.61. ..

[The bug's discoverer writes it was] found with what he calls his "trusty ai clanker machine" and no help from anyone else. He had even agreed to Andy's request to not disclose the findings. Unexpectedly, a third person, still unnamed, found the same bug using AI a few hours later. Anticipating that there would be more people finding the same bug, [he] decided to post the flaw on HackerOne.

The project's GitHub page and all the related repositories are still there. Nothing has been archived as of today, and if you wanted to, you could start contributing to the PS5 Linux project by taking over any pending work or cooking up new improvements... The PS5 Pro support Andy was building never reached the repository, so you would have to start from scratch... While Andy's departure is a blow to the plan for supporting newer PS5 firmware and the PS5 Pro, other contributors have shown that they can deliver work on the loader without him, and I am hopeful more will follow.

Reservations are now live for Valve's "Steam Frame" VR headset (with its Linux-based SteamOS and an ARM CPU). "It starts at $1,059 for 256GB or $1,299 for 1TB," reports CNET, "and every purchase includes a copy of Half-Life: Alyx if you don't already own it." Reservations are open through Sept. 17 at 10 a.m. PT, "with customers randomly assigned a place in line after the reservation window closes."

CNET's editor at large even argues that the Steam Frame "isn't necessarily the future of XR, as much as it's a framework for evolving beyond the present." Their review calls it an "ambitious" VR headset that "feels like an experiment in progress." The ability to run other apps in windows can make Frame feel, at times, almost like a computer. Linux apps in desktop mode range from Chromium to Firefox to a bunch of other tools. I watched YouTube in one window while playing Portal 2 in other, and started to marvel at how flexible Frame could be. But VR games require a full immersive takeover of the headset... The Steam Frame can convert games intended for both PC VR and even Android APK files, using a conversion tool called Lepton... I haven't sideloaded anything yet, but Steam Frame in theory could be a Rosetta Stone for VR gaming, even tapping into some Android XR titles, but not out of the box...

2D games can be projected onto a near-range or farther-off theater mode screen that can be dragged around, resized and turned into a curved or flat monitor, much like with the Apple Vision Pro, Samsung Galaxy XR or Meta Quest. You can download any game in your Steam library to test, even if it's not technically listed as "Great on Frame" yet...

But the name "Frame" suggests a framework, something Valve's team acknowledged when I spoke to them during my review process... "We want this to be your PC, and people mod it, take it apart, make accessories for it," says Jeremy Selan, a software developer on the Steam Frame team. "We'll be putting out the CAD for all these [Steam Frame] systems. This is entirely based on open-source technology stacks based upon SteamOS. Our hope is that this isn't just one device, that this would be sort of the root of a growing SteamOS ecosystem. It already encompasses gaming and Proton and SteamOS and those Linux gaming capabilities. This is going to lay the foundation for a new sort of evolutionary tree of that, to also bring it into the VR and XR space."

Nearly 1900 Blizzard Entertainment workers "voted to ratify their first union contract with parent company Microsoft after over two years of bargaining," reports Kotaku, "consolidating Blizzard's many smaller unions into three larger bargaining units."

The workers now gain new protections "on issues such as generative AI, crediting, remote work, and layoffs." [The contract] acknowledges that AI tools "may be useful in the game development process to support human judgment and creativity and that AI-assisted workflows remain subject to appropriate human control and review for accuracy and quality." But it also stipulates that any implementation of AI technology that would materially impact work performed by union employees must have its impacts bargained over before it can be implemented.

Other sections cover issues such as crediting (guaranteeing that current and former employees are credited by name in all games they work on) and remote work (designating certain roles as hybrid in-office and providing procedures for individuals to apply for their roles to be fully remote). It also contains a lengthy section on how layoffs may be conducted, including a required 60-day notice period (or pay in lieu of notice), a guarantee of one week of severance for every six months of employment, and 14 months of recall rights. The contract also guarantees successorship, meaning if Blizzard is ever acquired by another company, the contract would remain intact.
"Workers also contractually locked in their current hybrid work schedule," reports the gaming news site Aftermath, "meaning that Blizzard can't suddenly change it, as has been a labor-unfriendly trend in the games industry over the past couple years." Fully remote workers scored a big win as well. "I'm remote, and we grandfathered everyone who is remote to stay remote, so we can't be magically called to an office that we've never worked at before," [said Diablo senior environment artist Mahreen Fatima].
And "The contract also elevated pay floor," reports the Yakima Herald-Republic. "Across the board, workers secured a 1.25% pay increase, but some workers who were paid below $50,000 per year will walk away with pay increases that are as much as 34%."

Last week, Google announced that it managed to produce a detailed 3D reconstruction of an adult male fruit fly's brain and central nervous system. A few days later a software engineer at Coinbase said the fly brain was being trained to play the original Doom. "Each Doom frame stimulates sensory neurons," says Alex Wormuth. "Neural activity is mapped to game controls. Damage triggers a stimulus to two PPL101 dopamine cells as reinforcement." Since then, the digital brain model has been repurposed to control other games like Beat Saber and Super Mario 64. PC Gamer reports: You can even watch the fruit fly play in real time via Wormuth's website, and it not only shows the point of view in Doom, but can also show a third-person render of the fly going around Doom maps. As of the time of writing, the fly is on round 6385 and, well, it's not very good. Sorry, fly.

But modders aren't done here. They have also somehow managed to make the fruit fly play Beat Saber, and play it pretty well. Lyra Bubbles on X has used the brain and replays of a song in Beat Saber to teach the fruit fly where to hit and why, via Reinforcement Learning. That does mean it's not organically reacting to the notes popping up on screen, but it is receiving input and responding to stimuli. Lyra says, "Further training is to reduce reliance on external signals and allow it to play fully reactively with no input data."

And, after "pivoting to fly engineering in 2026", Jessica Paquette also shared on X their experience running the digital fly brain through Super Mario 64. If you think that is all the game's modders made the fruit fly play, think again, as YouTuber Ro0oney even put it in Minecraft. But this time, Ro0oney used Flywire.AI, a similar project made in collaboration with Princeton University. The number of neurons are different (160,000+ vs 139,255), and Google analyzed a male brain whilst Flywire analyzed a female brain, but the basic idea is the same.

Sony reportedly pulled PlayStation funding from Hideo Kojima's upcoming espionage game Physint over concerns about its ballooning budget, missed deadlines, profitability, and the fact that it would not remain permanently exclusive to PlayStation. Kojima Productions has since struck a deal with Xbox, which plans to publish the game on both Xbox and PC. It's also secured film and television rights. Bloomberg reports: The new game, Physint, hasn't yet been shown publicly but excited fans when it was announced two years ago with its promise of returning to the "espionage action" genre Kojima pioneered with Metal Gear Solid, the series that propelled him to industry stardom. Kojima surprised fans this week when he announced he would be publishing Physint with PlayStation's biggest rival, Microsoft Corp.'s Xbox.

On Wednesday night, Kojima wrote on social media that over the summer his company had "unexpectedly received notice" that PlayStation was pulling out of funding the game. "Physint is an important project both to me personally and to Kojima Productions," he wrote. "Determined to keep the project alive, we have spent the last three months searching tirelessly for a new partner."

PlayStation also addressed the split on social media, saying it had made the "difficult decision to step away." Microsoft said it was "honored" that Kojima chose Xbox and that the two teams plan to collaborate beyond games on films and television, too. [...] The decision to part ways with Kojima is a significant move for PlayStation that may have ripple effects.

[...] One key factor is the PC platform, where the Death Stranding games have generated some revenue. Earlier this year, Sony decided it will no longer release single-player PlayStation games on PC, Bloomberg reported. Sony would therefore not benefit when Kojima Productions released a PC version of Physint on its own or with a different publisher, as it did for the first Death Stranding. But Xbox releases all of its games on PCs and plans to publish Physint on PC and Xbox, said the people. "Betting on Kojima-san is an easy call," said an Xbox spokesperson. "We believe in his team's ability to build AAA games with groundbreaking, new IP and we believe in OD, Physint, and our growing partnership."

An anonymous reader quotes a report from Ars Technica: Those who remember PC gaming in the days before Steam may have fond memories of the "big box" packaging that made those games stand out as shelf eye candy and sought-after in-home collectibles. Today, PC gaming platform GOG is hoping to reignite some of the nostalgia for those days by adding downloadable 3D models and printable, foldable high-res packaging scans for a handful of PC games on the platform.

Thus far, the "Printable Big Box" collection on GOG is limited to just five games: Armikrog, Descent, Hitman: Codename 47, Myst, and Star Trek: 25th Anniversary. Players browsing those games on the GOG store will now see "3D Boxes" listed among the included "Goodies" before purchase. Owners of those games on GOG can download a ZIP file containing a version of the box art as an animated 3D object file (in an easy-to-open GLB format) and a "flat printable template" in PDF, SVG, and Adobe Illustrator formats. Those downloads allow for what GOG calls "a proper papercraft project for anyone who misses shelves full of PC game boxes."

The physically focused expansion of the existing GOG Preservation Program comes through a partnership with Benjamin Wimmer's Big Box Collection website, which has grown since 2015 to include over 1,000 3D scans from his private collection of physical PC games. In an interview with GOG, Wimmer said that while he appreciates the artistry of a good old-fashioned big box, he also appreciates their evolution into the "interactive cards" on modern digital storefronts that "provid[e] us art, screenshots, gameplay videos and whatnot and that not shown as a box, [it] is just good UX." "Physical media doesn't survive the way software can -- boxes get lost, crushed, thrown out," GOG writes in today's announcement. "Scanning them, and letting you print your own, is preservation in a different shape: the same mission that keeps these games running on modern PCs, applied to the objects they used to come in."

Rockstar Games and the mayor of Miami-Dade county are discussing a joint marketing campaign transforming parts of the county to look like areas from Grand Theft Auto 6, reports the blog Rock Paper Shotgun: The proposed publicity event would include "an immersive arrival experience" at Miami International Airport. with signs for Vice City and planes coated in GTA 6 livery, together with branded Metromover skytrains and specially designed manhole covers... [I]t proposes a dockyard visual installation inspired by GTA 6's Port Gellhorn, incorporating cargo containers, cranes, and cruise ships. There's also talk of a "Vice City Motor Fest", which might feature "classic cars, customized vehicles, lowriders, motorcycles, tropical graphics, and local entertainment within a controlled, family-appropriate setting." Attendees would presumably be discouraged from nicking the cars...

As it happens, Rockstar have embedded a team in Miami to sponge up the ambience, research Miami culture, and study the habits of residents — including "ex-criminals", in the careful phrasing of senior vice president of narrative Rupert Humphries.
The pitch suggested murals, "wrapping" buses (with special signs at transit stops), and even a Vice City-inspired baggage-claim installation at the airport. The pitch also suggested the library offer recording equipment for "Vice City Radio" to capture music (as well as podcasting, oral histories, neighborhood storytelling) — along with " limited-edition GTA VI-inspired library cards, collectible bookmarks, Miami-themed reading and music lists, and demonstrations of the new recording and production equipment."

Though nothing has been formally agreed to or approved, the mayor's office confirmed the discussions, reports Axios.

The sheriff of Miami-Dade county "has publicly opposed plans to transform the city into a real version of Grand Theft Auto 6's "Vice City", reports Kotaku. The sheriff's reason? The videogame city "includes murder, robbery, drug trafficking, carjacking, violence against law enforcement," as well as "other conduct" that the police department works "every single day to prevent."

Microsoft is imposing monthly limits on Xbox Cloud Gaming starting in November, with Game Pass Ultimate, Premium, and Essential subscribers getting 15, 10, and 5 hours respectively before they have to buy additional playtime. "Currently, Game Pass subscribers can stream without these monthly hour limits," notes IGN. From the report: The change means those who use cloud gaming most via Game Pass will end up having to pay more, although Microsoft said this impacts 4% of Game Pass subscribers. Also in November, Microsoft said players will be able to buy cloud playtime hours through the Xbox Store and 'stream eligible games they own on supported devices' without subscribing to Game Pass.

In a blog post, Microsoft said it was making the changes because the cost of providing cloud gaming has grown as more people use it and play for longer. The monthly limits, Microsoft continued, will mean it can invest in reliability and performance. But it said it understood that for some players the practical result is a higher cost.

A massive 12TB archive of old Steam2 content has surfaced online, apparently containing nearly every version of games uploaded to Valve's servers between 2003 and 2013, including unreleased prototypes, playtest builds, and cut content. Early discoveries include deleted Portal 2 material, files tied to Half-Life 2: Episode 3, and beta builds of games like Left 4 Dead 2, CS: GO, Spore, and Dragon Age: Origins. Researchers claim much of the material was once accessible through an unsecured public API. Ars Technica reports: The reason this weekend's leaked content cuts off abruptly in 2013 is because that's when Valve updated its content distribution system from "Steam2" to the current SteamPipe system. In moving from a proprietary file distribution format to standard HTTP file trees, the new system removed various update approval bottlenecks on Valve's end and streamlined update and patch downloads so they only reflected file differentials.

Publicly accessible early versions of some games released before this SteamPipe transition had been considered lost content by archivists, no longer accessible from Valve itself and living on only as local downloads on aging machines. Apparently all that content wasn't as lost as many thought, though. Longtime Valve watcher and data miner Gabe Follower (previously) wrote on social media this weekend that he had "verified that everything in Steam2 Teraleak was obtained via a publicly accessible [API] endpoint. It's Valve's fault..." Spanish-language Valve streamer and analyst Scolcer also said on social media (via machine translation) that the teraleak was "obtained from a site that was 100% accessible to the public. It was there for everyone to download. No passwords. Nothing. Hidden in plain sight, but with no protection whatsoever."

What's unclear right now if that API and publicly available Steam2 server content were accessed recently or if this weekend's leak represents content that was privately archived before the 2013 server transition and is just now being made public. "It could more-so be a collection of different people that knew about it and accumulated whatever people had downloaded back then into this massive archive," said The One Epicplayer, a moderator on the Valve Cut Content (VCC) Discord, which has long followed Valve betas and leaks. "I haven't been filled in on the full details but my suspicion is that these depot [files] were downloaded a long time ago and sat in a private collection," CrazyBubba, another VCC Discord moderator, told Ars. "There were a lot of leaks a few years back and many folks hoarded files for years. ... historically there have been issues with people lording content over other members."

A readme file included with the leak offers "warm n good wishes to all hoarders who had stuff from this collection" and encourages users to mirror and share it as widely as possible. On the VCC Discord, a user purporting to be the original uploader of the teraleak (who offered screenshots of a 22TB server upload log among their evidence) wrote that "getting this out really took a significant amount of effort from me and I would like it if it didn't go to waste."
