Back in 2013, Nvidia introduced a new technology called G-Sync to eliminate screen tearing and stuttering effects and reduce input lag when playing PC games. The company accomplished this by tying your display's refresh rate to the actual frame rate of the game you were playing, and similar variable refresh-rate (VRR) technology has become a mainstay even in budget monitors and TVs today.

The issue for Nvidia is that G-Sync isn't what has been driving most of that adoption. G-Sync has always required extra dedicated hardware inside of displays, increasing the costs for both users and monitor manufacturers. The VRR technology in most low-end to mid-range screens these days is usually some version of the royalty-free AMD FreeSync or the similar VESA Adaptive-Sync standard, both of which provide G-Sync's most important features without requiring extra hardware. Nvidia more or less acknowledged that the free-to-use, cheap-to-implement VRR technologies had won in 2019 when it announced its "G-Sync Compatible" certification tier for FreeSync monitors. The list of G-Sync Compatible screens now vastly outnumbers the list of G-Sync and G-Sync Ultimate screens.

Today, Nvidia is announcing a change that's meant to keep G-Sync alive as its own separate technology while eliminating the requirement for expensive additional hardware. Nvidia says it's partnering with chipmaker MediaTek to build G-Sync capabilities directly into scaler chips that MediaTek is creating for upcoming monitors. G-Sync modules ordinarily replace these scaler chips, but they're entirely separate boards with expensive FPGA chips and dedicated RAM.

Intel will be releasing a microcode update to prevent further damage to crashing 13th- and 14th-generation desktop processors sometime this month if it can stick to its previously announced schedule. This fix should be available via BIOS updates from PC and motherboard makers and from Microsoft as a Windows update. But it will take time for those updates to roll out to users, and Intel has said that processors that are already exhibiting crashes have been permanently damaged and won't be fixed by the microcode update.

In an effort to provide peace of mind to buyers and cover anyone whose CPU is subtly damaged but not showing explicit signs of instability, Intel is extending the warranty on all affected 13th- and 14th-generation CPUs by an additional two years, Tom's Hardware reports. This raises the warranty on a new boxed Intel CPU from three years to five. For processors that came installed in pre-built PCs, Intel says users should reach out to their PC's manufacturer for support instead.

Though owners of high-end chips like the Core i9-13900K and Core i9-14900K were the most frequently affected by the crashing issue, Intel says that any 13th- or 14th-generation desktop CPU with a base power of 65 W or higher could ultimately be affected. This means that even slower, more budget-oriented chips like the Core i5-13400 could end up having problems.

The Book 8088 was a neat experiment, but as a clone of the original IBM PC, it was pretty limited in what it could do. Early MS-DOS apps and games worked fine, and the very first Windows versions ran… technically. Just not the later ones that could actually run Windows software.

The Pocket 386 laptop is a lot like the Book 8088, but fast-forwarded to the next huge evolution in the PC’s development. Intel’s 80386 processors not only jumped from 16-bit operation to 32-bit, but they implemented different memory modes that could take advantage of many megabytes of memory while maintaining compatibility with apps that only recognized the first 640KB.

Expanded software compatibility makes this one more appealing to retro-computing enthusiasts since (like a vintage 386) it will do just about everything an 8088 can do, with the added benefit of a whole lot more speed and much better compatibility with seminal versions of Windows. It’s much more convenient to have all this hardware squeezed into a little laptop than in a big, clunky vintage desktop with slowly dying capacitors in it.

Of the many oddities you can buy from Aliexpress, some of the weirdest are the recreations of retro computer systems in semi-modern designs. We're most intimately familiar with the Book 8088, a recreation of the original 1981 IBM PC inside a chunky clamshell laptop. The people behind the Book 8088 are also responsible for the Hand386, which is a bit like a late-80s PC stuck inside an old Palm Pilot or Blackberry, and a second revision of the Book 8088 with more built-in ports and a VGA-capable graphics adapter installed instead of a basic CGA adapter.

Whoever is selling these systems is now back with the Pocket 386, which combines Hand386-style internals with a clamshell design similar to the Book 8088. The result is the kind of IBM-compatible system that would have been common during the Windows 3.1 era, when MS-DOS still dominated (especially for games) but Windows was on the upswing.

The Biden administration will ban all sales of Kaspersky antivirus software in the US starting in July, according to reporting from Reuters and a filing from the US Department of Commerce (PDF).

The US believes that security software made by Moscow-based Kaspersky Lab represents a national security risk and that the Russian government could use Kaspersky's software to install malware, block other security updates, and "collect and weaponize the personal information of Americans," said US Commerce Secretary Gina Raimondo.

“When you think about national security, you may think about guns and tanks and missiles,” said Raimondo during a press briefing, as reported by Wired. “But the truth is, increasingly, it's about technology, and it's about dual-use technology, and it's about data.”

Microsoft is all-in on its Copilot+ PC push right now, but the fact is that they'll be an extremely small minority among the PC install base for the foreseeable future. The program's stringent hardware requirements—16GB of RAM, at least 256GB of storage, and a fast neural processing unit (NPU)—disqualify all but new PCs, keeping features like Recall from running on all current Windows 11 PCs.

But the Copilot chatbot remains supported on all Windows 11 PCs (and most Windows 10 PCs), and a change Microsoft has made to recent Windows 11 Insider Preview builds is actually making the feature less useful and accessible than it is in the current publicly available versions of Windows. Copilot is being changed from a persistent sidebar into an app window that can be resized, minimized, and pinned and unpinned from the taskbar, just like any other app. But at least as of this writing, this version of Copilot can no longer adjust Windows' settings, and it's no longer possible to call it up with the Windows+C keyboard shortcut. Only newer keyboards with the dedicated Copilot key will have an easy built-in keyboard shortcut for summoning Copilot.

If Microsoft keeps these changes intact, they'll hit Windows 11 PCs when the 24H2 update is released to the general public later this year; the changes are already present on Copilot+ PCs, which are running a version of Window 11 24H2 out of the box.

Apple's new iOS 18 and iPadOS 18 updates are mostly good news for users of older Apple devices—with the exception of 2018's sixth-generation iPad, the new updates will run on all the same hardware that can run iOS 17 and iPadOS 17.

For iPhones, that will cover everything from the iPhone XR/XS and newer, including the second-gen iPhone SE; the seventh-gen iPad and newer; the third-gen iPad Air and newer; the fifth-gen iPad mini and newer; all 11-inch iPad Pros; and the third-gen 12.9-inch iPad Pro and later. Here are the full support lists:

It's a bit odd that the seventh-gen iPad makes the cutoff while the sixth-gen model does not, given that both use the same Apple A10 processor. But the seventh-gen iPad has 3GB of RAM instead of 2GB. This is the same amount as the third-gen iPad Air and fifth-gen iPad mini—apparently that extra gigabyte is crucial for running iPadOS 18's new features.

Most owners of aging Intel Macs got a bit of a reprieve today when Apple announced macOS 15 Sequoia—this new macOS release will run on the vast majority of the hardware that can currently run macOS 14 Sonoma. Intel Macs released between December of 2017 and 2020 are mostly eligible for the new update, though newer models with Apple Silicon chips will be needed to support some of the new features.

Apple's full support list for Sequoia is as follows:

Generally, all of these Macs include Apple's T2 chip, a co-processor installed in late-model Intel Macs that bridged the gap between the Intel and Apple Silicon eras. There are two exceptions. The biggest is the 2018 MacBook Air, which did come with an Apple T2 but also shipped with a weak dual-core processor and integrated GPU that Apple has apparently decided aren't up to the task of handling Sequoia. The other is the 2019 iMac, which for whatever reason shipped without a T2. Apple says the iPhone mirroring feature does require the T2 chip, so it presumably won't work on the 2019 iMac.

Apple has formally announced macOS 15 at its Worldwide Developers Conference. Codenamed Sequoia, the new release brings a combination of iOS 18 features and a few Mac-specific things to the devices it supports.

Users who split their time between Windows and macOS will be the most excited to see that Apple has finally implemented a form of automated window tiling in macOS. This makes it easier to arrange windows automatically on your screen without manually dragging and resizing each one individually or switching into full-screen mode.

Another feature called iPhone Mirroring sends your iPhone's screen to your Mac, so you can use apps directly on your phone while manipulating them using your Mac's keyboard and trackpad. The iPhone audio is also streamed to your Mac. For privacy's sake, your phone's screen stays locked while apps are streaming to your Mac, and your Mac can also receive your iPhone notifications alongside your Mac notifications (no word on how the operating systems will handle duplicate notifications from Messages, Calendar, or other apps that are getting the same updates on both platforms).

On Friday, Microsoft announced major changes to its upcoming Recall feature after overwhelming criticism from security researchers, the press, and its users. Microsoft is turning Recall off by default when users set up PCs that are compatible with the feature, and it's adding additional authentication and encryption that will make it harder to access another user's Recall data on the same PC.

It's likely not a coincidence that Microsoft also quietly pulled the build of the Windows 11 24H2 update that it had been testing in its Release Preview channel for Windows Insiders. It's not unheard of for Microsoft to stop distributing a beta build of Windows after releasing it, but the Release Preview channel is typically the last stop for a Windows update before a wider release.

Microsoft hasn't provided a specific rationale for pulling the update; the blog post says the pause is "temporary" and the rollout will be resumed "in the coming weeks." Windows Insider Senior Program Manager Brandon LeBlanc posted on social media that the team was "working to get it rolling out again shortly."

Apple’s initial pitch for the tvOS and the Apple TV as it currently exists was centered around apps. No longer a mere streaming box, the Apple TV would also be a destination for general-purpose software and games, piggybacking off of the iPhone's vibrant app and game library.

That never really panned out, and the Apple TV is still mostly a box for streaming TV shows and movies. But the same App Store rule change that recently allowed Delta, PPSSPP, and other retro console emulators onto the iPhone and iPad could also make the Apple TV appeal to people who want a small, efficient, no-fuss console emulator for their TVs.

So far, few of the emulators that have made it to the iPhone have been ported to the Apple TV. But earlier this week, the streaming box got an official port of RetroArch, the sprawling collection of emulators that runs on everything from the PlayStation Portable to the Raspberry Pi. RetroArch could be sideloaded onto iOS and tvOS before this, but only using awkward workarounds that took a lot more work and know-how than downloading an app from the App Store.

Earlier this week, Apple took the wraps off of a thoroughly leaked iPad Pro refresh with a 1 minute and 8 second ad spot wherein a gigantic hydraulic press comprehensively smushes a trumpet, an arcade cabinet, a record player, paint cans, a piano, a TV, sculptures, a bunch of emoji, and plenty of other tools that one might loosely categorize as "artistic implements."

At the end of the ad, the press lifts away to reveal a somewhat thinner, somewhat faster version of Apple's iPad Pro. The message of the ad, titled "Crush!" and still available via Apple's YouTube channel and CEO Tim Cook's Twitter account, is obvious: look at all of the things we've squeezed into this tablet!

"Just imagine all the things it'll be used to create," wrote Cook.

Starting in March with the release of iOS 17.4, iPhones in the European Union have been subject to the EU's Digital Markets Act (DMA), a batch of regulations that (among other things) forced Apple to support alternate app stores, app sideloading, and third-party browser engines in iOS for the first time. This week, EU regulators announced that they are also categorizing Apple's iPadOS as a "gatekeeper," meaning that the iPad will soon be subject to the same regulations as the iPhone.

In a developer blog post released today, Apple said that it would comply with the EU's regulations "later this fall, as required." All changes that Apple has made to iOS on European iPhones to comply with the DMA will be implemented in the same way on the iPad, though it's not clear whether these changes will be brought to iPadOS 17 or if they'll just be a part of the upcoming iPacOS 18 update.

The EU began investigating whether iPadOS would qualify as a gatekeeper in September 2023, the same day it decided that iOS, the Safari browser, and the App Store were all gatekeepers.

Microsoft is currently investigating a bug in its most recent batch of Windows 10 and Windows 11 updates that is preventing some VPN software from working properly. The company updated its list of known Windows issues to say that it has recreated the issue on its end and that it's currently working on a fix.

The VPN issue affects all currently supported versions of Windows: Windows 10 21H2 and 22H2; Windows 11 versions 21H2, 22H2, and 23H2; and Windows Server 2008, 2008 R2, 2012, 2012 R2, 2016, 2019, and 2022.

Microsoft says the problem was caused by update KB5036893, which was initially released on April 9, 2024. The update makes "miscellaneous security improvements to internal OS functionality," among a few other minor changes. The company hasn't provided specific information on what's been broken or what needs fixing, noting only that PCs "might face VPN connection failures" after installing the update.

Bloomberg's Mark Gurman thinks that Apple's M4 chips for Macs are coming sooner rather than later—possibly as early as "late this year," per a report from earlier this month. Now Gurman says Apple could completely skip the M3 generation for some Macs, most notably the Mac mini.

To be clear, Gurman doesn't have specific insider information confirming that Apple is planning to skip the M3 mini. But based on Apple's alleged late-2024-into-early-2025 timeline for the M4 mini, he believes that it's "probably safe to say" that there's not enough space on the calendar for an M3 mini to be released between now and then.

This wouldn't be the first time an Apple Silicon Mac had skipped a chip generation—the 24-inch iMac was never updated with the M2, instead jumping directly from the M1 to the M3. The Mac Pro also skipped the M1 series, leapfrogging from Intel chips to the M2.

The miniaturization of retro tech has always been a major obsession for modders, from the person who fit an original NES into a Game Boy-sized portable to the person who made a mini-er version of Apple's Mac mini.

One mod in this storied genre that caught our eye this week is the "Short Stack," a scale model of the Nintendo Wii that packs the 2006 console's internal hardware into a 3D-printed enclosure roughly the size of a deck of playing cards.

"You could fit 13.5 of these inside an original Wii," writes James Smith (aka loopj), the person behind the project. All the design details, custom boards, and other information about recreating the mod are available on GitHub.

Apple has released a long list of medium-sized software updates for most of its devices today. The macOS Sonoma 14.4, watchOS 10.4, tvOS 17.4, and visionOS 1.1 updates are all available now, and most of them add at least one or two major features as they fix multiple bugs and patch security vulnerabilities.

The visionOS 1.1 release is the first major update for Apple's newest operating system, and as our coverage of the headset has demonstrated, there's still plenty of low-hanging fruit to fix. Most notably for people who are trying to use the headset for work meetings, Apple says that there have been multiple changes to the look of Personas, the 3D avatars that show up in your place when you're video chatting with the Vision Pro on your face. The update improves "hair and makeup appearance," "neck and mouth representation," and "rendering of the eyes," and while it's clear that it's an improvement over the 1.0 release of Personas, the core uncanniness still seems to be intact. The Persona feature is still labeled as a beta.

Apple has also made tweaks to the appearance and functionality of the headset's virtual keyboard, improved the Virtual Display feature's Mac connectivity, and added a handful of mobile device management features for IT administrators.
