AMD's FSR 4.1 now works on Radeon RX 6000 cards, Xbox Series X and S, and Ryzen AI Max, AI 9, and Z2 SoCs

Earlier this year, AMD brought the previously RX 9000-exclusive FSR 4 upscaling tech to Radeon RX 7000-series graphics cards and promised an early 2027 release for RX 6000-series products. Christmas has come early for RDNA 2 and many other Radeon gamers, as Radeon honcho Jack Hyunh has announced an FSR 4.1 release for Radeon RX 6000 series cards, Xbox Series X and Series S consoles, Ryzen Z-series handhelds, and machines with Ryzen AI Max and AI 9 chips today.

To accomplish this feat, AMD says it tweaked FSR 4.1's neural network model to support the INT8 shader hardware (as opposed to the higher-precision FP8 matrix acceleration hardware on Radeon 9000 cards). Additionally, the version specific to handhelds is slimmed down even further, to less than half the size of the full one.

AMD says that compared to FSR 3, games on the aforementioned GPUs and APUs will now deliver better image quality, all else equal. With Cyberpunk 2077 running in FSR Balanced mode at 4K, our quick testing with a Radeon RX 6900 XT shows that running FSR 4 costs just about 13% performance, a small price to pay for sharper and more stable visuals, especially in motion.

And the higher upscaling quality of FSR 4.1 might let gamers use Performance mode where they might previously have used Balanced, or so on, which might offset that performance cost.

There are more goodies in store, too. The Radeon team says that FSR Frame Generation now ought to have better frame pacing, resolving a longstanding complaint with the tech and potentially making for smoother gameplay with framegen enabled. Support for the Vulkan API with FSR 4.1 is set to arrive at some point, as well, a boon for some games and console emulators. Finally, AMD says FSR Ray Regeneration will also be coming to more games, too. The company showed the tech running in Warhammer 40,000: Darktide, and that integration is available now.

To get all this goodness into your GPU, you can download the just-released Radeon 26.10.1 drivers from the AMD Adrenalin application or directly from AMD's website. The updated software also adds support for Call of Duty: Modern Warfare 4, Star Wars: Galactic Racer, and Final Fantasy Resonance. You can check out the full release notes here.

For owners of Xbox and Ryzen Z2-series handhelds, AMD says that an update from their manufacturers will be forthcoming, as those devices depend on OEM-specific drivers.

We're pleased to see that Radeon gamers are getting upgrades for their existing graphics chips along the lines of what Nvidia has been delivering throughout 2025, because the way things are going, it looks like it'll be around 2077 before there will be a new gaming graphics card launch. If you're an RDNA 2 gamer, go give FSR 4 a shot and see what you think.

US restarts three shut-down nuclear reactors to feed AI data centers

The current and expected power draw of AI data centers has been the subject of strong discussion, but today, there appears to be some good news. Three U.S. nuclear reactors are being restarted after many years offline, expected to bring 2.25 GW total to the grid. According to a report, the Palisades Nuclear Plant in Michigan, the Crane Clean Energy Center on Three Mile Island (Pennsylvania), and the Duane Arnold Energy Center in Iowa are getting a fresh set of proverbial tires to get rolling again.

The Palisades plant was under active decommissioning, apparently marking this event as the first time a nuclear reactor is being put back to work after dismantling had begun. Despite what sounds like a tough starting point, this plant is the one that's furthest along, as it was loading fuel in August 2026 and is expected to generate 800 MW around March 2027.

Much like the other projects mentioned here, the Holtec Palisades firm running the reactor took a loan from the U.S. Department of Energy. Palisades borrowed from the DoE under the Biden administration's 2024 investment in nuclear energy, while the others were issued under the purview of the Trump administration's 2025 push.

The second reactor is the Crane Clean Energy Center on Pennsylvania's Three Mile Island, repurposing the facility's Unit 1. The project started in 2024, with Constellation Energy saying it would spend $1.6 billion total for the reactor. The firm then took a $1 billion loan from the Department of Energy in 2025. Microsoft is set to be the main customer, with a 20-year contract. This facility is projected to bring 835 MW online sometime in 2027.

This facility was famous in 1979 for the partial meltdown of its Unit 2, although mercifully the event had relatively tame environmental consequences. Constellation's ongoing project is restoring and refurbishing Unit 1, which didn't show significant issues until its 2019 decommissioning and has undergone a safety inspection from the Nuclear Regulatory Commission. This entity still needs to grant its blessing before the reactor starts loading fuel.

The Duane Arnold Energy Center in Iowa is the third unit being brought back to the grid, in a collaboration between NextEra Energy and Google. The predicted output is 615 MW, with the juice expected to start flowing in 2029. Next Energy CEO John Ketchum stated that the firm was happy with its cooperation contract with Google, as it meant that "none of the costs are being paid by residential customers in Iowa."

All three facilities had previously been shut down at various points as they were deemed too expensive to run, as labor and maintenance costs made nuclear-generated watts pricier than alternative means of production.

But the financial landscape for power has shifted, plus with such overwhelming demand and grid connections being a primary blocker for data center buildouts, their operators are likely willing to pay for premium power as long as they get it now instead of in a few decades.

Some quick browsing indicates that Michigan is going to need somewhere between 1.2 and 2.3 GW for data centers alone around 2030. Pennsylvania's forecast has a wide range of 0.8 to 3.4 GW, while Iowa's range is 1.55 to 2.8 GW. These figures are loose, as they include planned capacity for data center projects that may or may not end up being built, and whose timetables may slip due to economic conditions, hardware availability, and public resistance against expansive buildouts.

Modern software is built on the backs of low-paid maintainers, opening the door to potential threats

Modern computing systems and devices typically require pieces of crucial open-source software, typically maintained by unpaid or low-paid volunteers. Recently, a report collated a list of critical open-source projects, noting which of them are chronically underfunded and/or understaffed. The information is sobering: 11 out of 23 of the listed projects currently only have one or two maintainers, and funding is generally scarce and sometimes nonexistent.

The Data Drop's report on open-source maintainers identifies that having only one or two sets of eyes on critical pieces of software means that sooner or later something breaks β€” and it tends to do so in spectacular fashion, given its ubiquity. So, what happens when these projects, which are widely used across software, go underfunded or understaffed?

Lessons from the past

In 2014, the same year as Heartbleed, Shellshock made waves: a vulnerability in the Bash shell that's present in Linux, macOS, and Unix-type systems. The problem was traced back to a line of code present since 1989, displaying how even software that's thought to have all the bugs hammered out of it can still fall prey to attacks. A quick look at Bash's commit history shows it's almost exclusively maintained by Chet Ramey.

In 2016, ImageMagick was exploited, providing attackers with remote code execution. This library is used for image manipulation across a wide range of software, in webpages, mobile apps, and more. A 2020 analysis revealed that hundreds of security issues had been found over the years in its extensive codebase. Nearly every code contribution in the past couple of years has been done by an individual named Dirk Lemstra.

Contemporary examples include 2021's Log4Shell exploit, a critical vulnerability in the Apache Log4j logging library used in millions of servers. The libwebp image-handling library saw a zero-day vulnerability in 2023, and the xz compression library used across Linux and iOS was compromised in 2024.

Thankless work

Key points in the report mention specific repos, which might be under threat. Somewhat unsurprisingly, the low number of overall maintainers and the unpaid nature of the work make it unattractive to perform.

The main time-zone file used across Linux-based operating systems is maintained pro bono by Paul Eggert, a UCLA teacher. Core-js, a piece of support software that lets new JavaScript work in old browsers and is estimated by the author to be used in half of the busiest websites in the world, is handled by Denis Pushkarev. He once had to endure criticism from the community because he added a command-line message to the library's installer asking for help or a job.

The HarfBuzz library developed by Behdad Esfahbod is a cornerstone in ligatures and text shaping in Middle Eastern languages. In those writings, a letter changes shape and/or orientation according to what's around it. Esfahbod handles that vast majority of the project's code, and doesn't mention public or corporate funding.

Libjpeg-turbo handles JPEG images on Android, Firefox, LibreOffice, and every Chromium-based browser. It's kept ship-shape by D.R. Commander aka DRC, who occasionally is contracted for library-specific work, though at arguably modest values of "3-4 figures rather than 6 or 7." Libxml2, just like the label says, handles XML reading and writing across numerous applications and operating systems. Nick Wellnhofer, the original maintainer, stepped down in September 2025, after years of work with little income.

The SQLite project provides a one-file database that's exceedingly easy to integrate into most software, instead of complicated, resource-heavy databases, while still retaining standard SQL language and accouterments. Thanks to its ease of use, it found its way into an astonishing number of applications. Examples include WhatsApp, Dropbox, Android, Windows, and all major browsers.

The project estimates that there are about a trillion instances of SQLite in use. Just four people keep this critical project together, and they've gone to the length of removing their names and photos from the project's page, as "there are a lot of crazy people in the world who might misuse that information." The project is funded by the offering paid support via the founder's company, though there's no word on effective income, especially when it presumably needs to feed four mouths.

Funding is there, but scarce

It's not all doom and gloom, though. Take curl (the software), for example. Almost every developer has used it, thanks to its URL-fetching abilities and extensive scripting options. The project was started by Daniel Stenberg, who is now paid to work full-time on it. The team has now grown to 11 and has received funding through Open Collective and Germany's Sovereign Tech Agency, among others.

Likely due to the lessons learned from their past respective debacles, both the Log4j and OpenSSL projects are likewise funded by the Sovereign Tech Agency, as are the FFmpeg video file handler and the OpenSSH secure shell software that's ubiquitous in Linux servers.

All things considered, it's easy to argue that the critical importance of all the aforementioned software merits sizable investments from industry players, especially those whose commercial products benefit the most from the community's efforts. Plus, even if the firms feel no moral obligation to contribute, in the day and age where AI agents are finding exploitable vulnerabilities in hours, donations to these open-source projects could also be considered investments.
