Jeff Grubb, writing for VentureBeat: One of the tidbits revealed during the first Xbox 20/20 event today is that Dirt 5 supports 120 frames per second on Xbox Series X. Publisher Codemasters' racing game is coming in October, but it supports Smart Delivery. So if you get it for Xbox One, you'll get the Xbox Series X version at no additional cost. And what does the Xbox Series X-optimized version of Dirt 5 get you? In an interview with the Xbox team, Codemasters confirmed that Dirt 5 supports the next-gen console's high-framerate feature. This means you can drive around the rally racer at 4K and 120 frames per second. High framerate is one of a number of key features for the next-gen consoles. And that makes sense. Racing games already have nearly photorealistic visuals. More graphical effects are not going to make much of a difference to the presentation of a Dirt 5. So this enables Codemasters to put that extra horsepower toward running the game faster.

OK, so the Xbox Series X can run Dirt 5 at up to 120fps, but that's not going to matter if you don't have the right display. High-refreshrate content is common on the PC, but consoles have primarily topped out at 60fps. Because of this it hasn't matter that most TVs top out at 60Hz. But it is a problem for the next-gen consoles. To actually see Dirt 5 running at 120fps, you'll need a TV that runs at 120Hz or faster. That means the TV updates its frames 120 times every second. The good news here is that a lot of TVs already have this feature. The bad news is that even if you have an HFR panel, support is a lot more complicated than that. The issue comes down to the audio/video interface running between your TV and the Xbox Series X.

An anonymous reader quotes a report from The Hollywood Reporter: Call of Duty maker Activision has prevailed in a closely watched trademark dispute brought by AM General, the government contractor for Humvees. On Tuesday, a New York federal judge responded favorably to Activision's argument that it had a First Amendment right to depict contemporary warfare in its game by featuring Humvees. "If realism is an artistic goal, then the presence in modern warfare games of vehicles employed by actual militaries undoubtedly furthers that goal," writes U.S. District Court Judge George B. Daniels in granting summary judgment in favor of Activision. The video game publisher fought AM General's claims along with Major League Gaming Corp., a professional esports organization. The dispute was potentially worth tens of millions of dollars, and the discussion attracted intellectual property professors and the Electronic Software Association to weigh in with amicus briefs.

Microsoft revealed new details on its next-generation console, text, on Monday morning, confirming specifications on what the company calls its "superior balance of power and speed" for its new hardware. From a report: The next-gen Xbox, Microsoft said, will be four times as powerful as the original Xbox One. The Xbox Series X "next-generation custom processor" will employ AMD's Zen 2 and RDNA 2 architecture, head of Xbox Phil Spencer wrote on the Xbox website. "Delivering four times the processing power of an Xbox One and enabling developers to leverage 12 [teraflops] of GPU (Graphics Processing Unit) performance -- twice that of an Xbox One X and more than eight times the original Xbox One," Spencer said. He called the next-generation Xbox's processing and graphics power "a true generational leap," offering higher frame rates -- with support for up to 120 fps -- and more sophisticated game worlds.

That 12 teraflops claim is twice that of what Microsoft promised with the Xbox One X (then known as Project Scorpio) when it revealed the mid-generation console update back in 2016. Spencer also outlined the Xbox Series X's variable rate shading, saying, "Rather than spending GPU cycles uniformly to every single pixel on the screen, they can prioritize individual effects on specific game characters or important environmental objects. This technique results in more stable frame rates and higher resolution, with no impact on the final image quality." He also promised hardware-accelerated DirectX ray tracing, with "true-to-life lighting, accurate reflections and realistic acoustics in real time." Microsoft also reconfirmed features like SSD storage, which promise faster loading times, as well as new ones, like Quick Resume, for Xbox Series X.

Gizmodo shares the saga of a now-deleted video claiming to show Call of Duty's new "battle royale" mode: The YouTube video, initially posted by a user who goes by TheGamingRevoYT, was slammed with a copyright claim and ripped from the platform. Meanwhile, other gamers noticed that Reddit posts and Twitter threads even mentioning the upcoming release were being taken down for "copyright infringement." Last week, when one Redditor found a leak of what appeared to be the cover art for the new game, that got hit with a copyright claim too — and some other legal action. According to court documents obtained by TorrentFreak, Activision has spent the last week actively subpoenaing Reddit to uncover the identity of the Reddit user who leaked the initial artwork...

It's worth noting, as TorrentFreak points out, that there wasn't technically any "infringing content" posted to the thread itself — just an external link to a site that hosted the image in question.

Id software has released a new trailer for their upcoming Doom sequel set on a demon-infested planet Earth in the year 2151. And GameSpot has uploaded a 10-minute clip of gameplay while Collider released 15 minutes.

Collider writes: Doom Eternal takes everything that was gloriously batshit about Doom 2016, throws it in a Lamborghini full of Slayer albums and catapults it into the sun. This game is out of its goddamn mind in the best possible way, and I literally cannot wait to get my hands on the full version... The Fortress of Doom is massive. I wasn't able to access every area, and could only guess at the function of some of the areas I did see. One section had the original Doom Marine costume on display in a glass case, and the game's director, Hugo Martin confirmed that the skin is an unlockable. Moreover, he indicated that there are several unlockable player skins in the game, including one he was clearly excited about but couldn't reveal, saying that it was still in the licensing approval stage...

Doom Eternal, like its predecessor, is a fast game, pitting you against hordes of powerful enemies that force you to constantly be on the move and quick-swapping weapons to inflict maximum damage while avoiding death. You have a few tools at your disposal to earn guaranteed life, ammo, and armor, which are the over-the-top glory kills, the terrifying chainsaw, and the brand-new flame belcher respectively. Glory kills are special instant-death maneuvers you can unleash on enemies after staggering them, and the addition of a retractable arm blade has heightened the graphic absurdity of them to such a degree that I was giggling like an idiot every time I pulled one off.

I spent the next three hours murdering my way across three massive levels that were incredibly varied in terms of design, beginning in a blasted post-apocalyptic city, then moving to a vast overgrown temple, and finally ending up in a heavily-fortified arctic base... Each stage had a completely different feel -- the city was very ground-based, with dark subway tunnels and skeletal office buildings. The temple was spread out across what felt like miles, with an unexpected amount of verticality and traversal thanks to the new climbing mechanic. Yep, Doom Guy can now cling to certain walls, as well as swing from poles to extend his jump and gain access to distant ledges. The climbing controls are a bit funky, like Spider-Man with a rotator cuff injury, but the traversal puzzles are fun and satisfying, and allow for some truly massive environments...

Martin promised that players will continue to be introduced to new enemies and environments right up until the end of the 22+ hour campaign. He describes Doom Eternal as a thinking person's action game, and that the team's goal was to create a combat puzzle worth your time.
DOOM Eternal is scheduled to be released on March 20th.

theodp writes: Over at Polygon, games journalist Colin Campbell remembers the late Silas Warner in The Man Who Made Wolfenstein. Before Doom, there was Warner's Castle Wolfenstein (1981) and Beyond Castle Wolfenstein (1984), which counted id Software's legendary John Carmack and John Romero as fans. After completing his degree in Physics at Indiana University, Warner found work at IU installing a new system called PLATO, which he used to fork John Daleske's Empire (1973), which is sometimes credited as being the first multiplayer shooting game. Ultima creator Richard Garriott called Warner's Escape (1978) a major inspiration that "changed my life." Warner's Robotwar (manual, pdf) also did double-duty as a stealth learn-to-program tutorial. Sadly, Warner was plagued with bad health and passed away at age 54 without receiving the proper credit or rewards he was due.

FPS (first-person shooter) games have been a staple in the video game industry ever since the explosion of Wolfenstein 3D back in 1992. Since then, the genre has been evolving with graphical upgrades, huge budgets, and an eSports ecosystem. But what about its core, the shooting mechanics? How have we progressed on that front? Why do some guns feel like it's the real thing, while others feel like toys?

At the 2019 Game Awards today, Microsoft revealed the name and console design of its next-generation gaming console: Xbox Series X. The Verge reports: The console itself looks far more like a PC than we've seen from previous Xbox consoles, and Microsoft's trailer provides a brief glimpse at the new design. The console itself is designed to be used in both vertical and horizontal orientations, and Microsoft's Xbox chief, Phil Spencer, promises that it will "deliver four times the processing power of Xbox One X in the most quiet and efficient way."

The Xbox Series X will include a custom-designed CPU based on AMD's Zen 2 and Radeon RDNA architecture. Microsoft is also using an SSD on Xbox Series X, which promises to boost load times. Xbox Series X will also support 8K gaming, frame rates of up to 120 fps in games, ray tracing, and variable refresh rate support. Microsoft also revealed a new Xbox Wireless Controller today. "Its size and shape have been refined to accommodate an even wider range of people, and it also features a new Share button to make capturing screenshots and game clips simple," explains Spencer. This updated controller will work with existing Xbox One consoles and Windows 10 PCs, and will ship with every Xbox Series X.

Scott Stein, reviews Google Stadia cloud gaming service for CNET: Stadia's launch day was earlier this week... sort of. Really, consider this the start of Stadia's early-access beta period. Because Google's big promises haven't arrived, and at the price of the Stadia's Founder's Edition, I can't recommend anyone jump onboard at the moment. Google's experimental game streaming service, Stadia, launches without many of its promised features, and just a handful of games. It works, but there's not much incentive to buy in. We've heard about the promises of streaming games over the internet for a decade. Stadia really does work as a way to stream games. I've only played a couple of the 12 games Google promised by Tuesday's launch, though. That short list pales compared to what Microsoft already has on tap for its in-beta game-streaming service, xCloud. It's no match for what Nvidia's game streaming GeForce Now already has or what PlayStation Now offers. Prices of Stadia games at launch in the US are below. They're basically full retail game prices. This could get crazy expensive fast.

[...] Stadia has so few games right now, and I'm trying them with no one else online. It isn't clear how things will work now that the service is going live, and what other features will kick in before year's end. I'm curious, but I might lose interest. Others might, too. I have plenty of other great games to play right now: on Apple Arcade, VR and consoles such as the Switch. Stadia isn't delivering new games yet, it's just trying to deliver a new way to play through streaming. One that you can already get from other providers. Until Google finds a way to loop in YouTube and develop truly unique competitive large-scale games, Stadia isn't worth your time yet. Yes, the future is possibly wild, and you can see hints of the streaming-only cloud-based playground Stadia wants to become. But we'll see what it shapes into over the next handful of months and check back in. Raymond Wong, writing for Input Mag looks at the amount of data playing a game on Stadia consumes and how the current state of things require a very fast internet connection to work: Like streaming video, streaming games is entirely dependent on your internet speed. Faster internet delivers smooth, lag-free visuals, and slower internet means seeing some glitches and dropped framerates. Google recommends a minimum of connection of 10Mbps for 1080p Full HD streaming at 30 fps with stereo sound and 35Mbps for 4K resolution streaming (in HDR if display is supported) at 60 fps with 5.1 surround sound. Reality didn't reflect Google's advertising, though. Despite having a Wi-Fi connection with 16-20Mbps downloads in a hotel room in LA, streaming Shadow of the Tomb Raider and Destiny 2 to my 13-inch MacBook Pro wasn't 100% stable. The visuals would glitch out for a second or two about every 10 minutes of playtime. [...] A fast internet connection isn't the only thing you need for Stadia to work right. You need a lot of bandwidth, too. One hour of playing Red Dead Redemption 2 at 1080p resolution on my 46-inch HDTV via a Chromecast Ultra ate up 5.3GB of data. This seemed insane until I saw an hour of Destiny 2 on a Pixel 3a XL with 6-inch, 1080p-resolution display gobbled up 9.3GB of data!

An anonymous reader quotes the Guardian: "Give us more guns!" is a common battle-cry among players of first-person shooters, the videogame industry's bloodiest genre. Doom co-creator John Romero has a rather different opinion. "I would rather have fewer things with more meaning, than a million things you don't identify with," he says, sitting in a Berlin bar mocked up to resemble a 1920s Chicago speakeasy. "I would rather spend more time with a gun and make sure the gun's design is really deep -- that there's a lot of cool stuff you learn about it...."

Modern shooters are too close to fantasy role-playing games in how they shower you with new weapons from battle to battle, Romero suggests. This abundance of loot -- which reflects how blockbuster games generally have become Netflix-style services, defined by an unrelenting roll-out of "content" -- means you spend as much time comparing guns in menus as savouring their capabilities. It encourages you to think of each gun as essentially disposable, like an obsolete make of smartphone. "The more weapons you throw in there, the more you're playing an inventory game." Romero contrasts this to the sparing design of the original Doom, which launched in 1993 with a grand total of eight guns. "For Doom, it was really important that every time you got a new weapon, it never made any previous weapons useless...."

Doom is also a game that knows how to keep a secret. It isn't just a firefight simulator but a treacherous, vaguely avant-garde work of 3D architecture. Its levels are mazes of hidden rooms and camouflaged doors that screech open behind you -- sometimes revealing a pile of ammunition, sometimes disgorging enemies into areas you've cleared. Today's shooters set less store by secret spaces, Romero says, because they cost so much to make.

"Fortnite just blew up its entire map and all that's left is a black hole," reports TechCrunch. Some are speculating that this is simply a teaser for a new Fortnite map, but it's unclear when that new map will arrive... Fortnite's website is currently just a Twitch stream featuring a black hole.
The Washington Post reports: Anyone looking for clues on Fortnite's multiple social media accounts were left staring at the same image. The same black hole greets all visitors to Fortnite's Instagram. And intrepid players discovered that inputting the infamous "Konami code" launches a Galaga-style shooting game starring the mascot of Greasy Grove restaurant Durrr Burger.... As the event happened, many Twitch users reported having trouble using the popular streaming service, with more than 4 million people watching the event. Millions more tuned in on YouTube and Twitter, as well.... Rumors have swirled that the famous Fortnite map was going to be completely replaced, and given that everything's now gone, it sounds plausible...

Fortnite's Season 10 has been expected to end soon, and since last year, spectacular one-time live events within the game have been used to build hype, signal changes to the one map the game has used for two years, and usher in a new season and battle pass. This time, players who logged in at 2 p.m. Eastern time witnessed a rocket launch from the Dusty Divot area of the island, which turned into multiple rockets, all zipping around in a manner similar to the rocket that players saw in the first season-ending live event in Season 4. The rockets then converged onto an area where a meteor was landing, and the collision caused players to fly up into the air to witness a black hole suck the entirety of the game inside.

And since then, players have been left with nothing but the black hole.

"As we've discussed in the past, old people are some of the only video game streamers worth watching," writes the AV Club: Filled with the wisdom that comes from age, seniors are the necessary corrective to Twitch and YouTube channels currently dominated by excitable whippersnappers. Fortunately, as outlined in a piece NBC's Kalhan Rosenblatt that explores this world, video games are gaining popularity among the elderly. The piece references a study that found "38 percent of Americans age 50 and older said they play video games" and looks at those who belong to this demographic.... Our old pal, the Skyrim-loving Shirley Curry pops up, too, when Rosenblatt gets into the seniors who stream games or upload videos of what they're playing online. Curry, who is 83, has "more than 700,000 subscribers on YouTube," and refers to her viewers as "grandkids," is mentioned alongside 66-year-old Twitch streamer GrandpaGaming (AKA Will R.). He streams games that include PlayerUnknown's Battlegrounds and Apex Legends, uploading highlights that show him kicking the ass of other players who, when their age is compared to his, are probably quite literal noobs.

c Rosenblatt mentions the social benefits of video games as well as studies that show how, "with their complex controls and fast pace" they provide "a mental workout for seniors" that could help "delay or slow the onset of degenerative neurological diseases, such as Alzheimer's or other forms of dementia." This means that, aside from providing a subgenre of game streams that are far more entertaining than the usual, these seniors are potentially improving their health as well.

$30 million in prizes were up for grabs, the largest ever for an esports event, and more than 40 million attempted to qualify for a spot. Now IGN reports: The grand champion of the Fortnite World Cup finals has been crowned. Kyle "Bugha" Giersdorf, a 16-year-old American boy, took home the trophy and a $3 million prize... "Words can't even explain [how I feel] right now," Giersdorf said from the Champion's circle. "I'm just so happy. Everything I've done, the grind, it's all paid off. It's just insane."
And the Guardian reports that a 15-year-old won $1.25 million (£1m) when his two-man team placed second in the duos competition. He told the BBC that his mother initially thought he was wasting his time. "Now I've proved to her that I can do stuff, I'm really happy," he said. With regard to spending the prize money, his mother said her son was not materialistic, and that she anticipated he would spend the prize money on a "lifetime of Uber Eats".
IGN also reported on another Fortnite drama: A pair of Fortnite World Cup competitors, formerly banned by Epic for cheating, were the target of much ire Saturday, as the crowd loudly booed one's appearance onscreen and subsequently cheered for their loss...

Epic Games previously banned XXiF and Ronaldo from Fortnite for 14 days, after an internal review found that the players had colluded with other players in order to acquire easy elimination points during week 3 of the Fortnite World Cup qualifiers, according to Dexerto. The pair were subsequently dropped from their team, Rise Nation. That initially sounded like the end of the whole matter, but then XXiF and Ronaldo qualified during the week 8 qualifier, finishing in third place and securing a spot during the finals.

XXiF and Ronaldo ended up placing 28th during the duos finals, securing them $50,000 each in prize money.
Fornite had to ban more than 1,200 Fortnite accounts for cheating in just the first week of the World Cup Open online.

To celebrate the 25th anniversary of Doom, there's now mobile versions in the Google Play Store, reports Android Police, "and since this is a 25th-anniversary release, it includes the fourth expansion Thy Flesh Consumed. It's the complete package folks, and it's finally available on Android as an official release."

And in addition, three Doom re-releases are now available for the Nintendo Switch, Xbox One, and PlayStation 4, reports the Verge -- though there was one little glitch: Bethesda says it'll get rid of the strange requirement that players must log into an online account before they play the newly re-released versions of Doom, Doom II, and Doom 3, which went live yesterday. Players quickly criticized Bethesda for the seemingly ridiculous limitation -- the first of these games was released more than 25 years ago, at a time when there was obviously no internet requirement. The online login will be made optional in a coming update, Bethesda said today.
The re-releases were part of QuakeCon 2019, reports IGN, noting that Bethesda also showcased Doom Eternal's multiplayer, "revealing new details about the unique 1v2 Battle Mode."

Forbes hails the re-releases as "id Software's fast-paced, ultra-violent...classic shooters," adding that "It appears the re-releases are actually Unity remakes, though whether much has changed beyond resolution support remains to be seen." But they may also have some other minor differences, Engadget reports: There have been a few other complaints as well, such as the addition of copy protection, graphical changes (such as filtering that softens those 1993-era graphics) and apparent music tempo slowdowns on the Switch. That's not including the removal of downloads for the old PS3 and Xbox 360 versions. It's not a fiasco, but these clearly weren't the straightforward ports some were expecting.

An anonymous reader quotes a report from PetaPixel: A team of scientists from the Swiss Federal Institute of Technology in Zurich (ETH Zurich) have figured out how to capture super slow-motion footage using what's called an "Event Camera." That is: a camera that sees the world in a continuous stream of information, the way humans do. Regular cameras work by capturing discrete frames, recapturing the same scene 24 or more times per second and then stitching it together to create a video. Event cameras are different. They capture "pixel-level brightness changes" as they happen, basically recording each individual light "event" as it happens, without wasting time capturing all the stuff that remains the same frame by frame.

As ETH Zurich explains, some of the advantages of this type of image capture is "a very high dynamic range, no motion blur, and a latency in the order of microseconds." The downside is that there's no easy way to process the resulting "footage" into something you can display using current algorithms because they all expect to receive a set of discrete frames. Well, there was no easy way. This is what the folks at ETH Zurich just improved upon, developing a reconstruction model that can interpret the footage to the tune of 5,000+ frames per second. The results are astounding: a 20% increase in the reconstructed image quality over any model that existed before, and the ability to output "high frame rate videos (more than 5,000 frames per second) of high-speed phenomena (e.g. a bullet hitting an object)," even in high dynamic range "challenging lighting conditions." Their findings have been published in a research paper titled High Speed and High Dynamic Range Video with an Event Camera.

malachiorion writes: Facebook just open sourced a simulator for testing and training embodied AI systems -- like virtual robots. They worked with AR/VR researchers to release the simulator along with what they say are the most photorealistic 3D reconstructions of real world places available. [Facebook Reality Labs have named this "the Replica data set".]

The crazy part: Because more frames are always better for training computer vision in simulators, it can run at 10,000 FPS!
The simulator's ability to hit 10K frames per second prompted an interesting follow-up on the original submission. "It's a totally useless framerate for humans -- just absolute overkill for our brains/eyeballs -- but it's apparently a benefit for AI systems."

"As more researchers adopt the platform, we can collectively develop embodied AI techniques more quickly," explains Facebook's blog post, "as well as realize the larger benefits of replacing yesterday's training data sets with active environments that better reflect the world we're preparing machine assistants to operate in."

And if you're worried about privacy, Facebook assures readers that "The data used to generate Replica scans was anonymized to remove any personal details (such as family photos) that could identify an individual. The overall reconstruction process was meticulous, with researchers manually filling in the small holes that are inevitably missed during scanning and using a 3D paint tool to apply annotations directly onto meshes."

"Online marketplace eBay has revealed how it boosted performance of a demanding web app by 50x using WebAssembly," reports TechRepublic: The "astonishing" speed-up after switching from a JavaScript-based to a largely WebAssembly-based web app was detailed by the eBay engineering team, who say the performance boost helped make it possible to build a highly-accurate barcode scanner as a web app... a feature it offers in its Android and iOS apps to allow sellers to scan items they are auctioning. "WebAssembly was different. It has tremendous potential, we just did not have the right use case. Well, that changed recently," write the eBay software engineering team.

One of the advantages of WebAssembly (Wasm) is that it offers code portability for a variety of languages, allowing developers to take code they've written for other platforms and compile to WebAssembly so it can run in major web browsers. Consequently eBay was able to take the existing version of its barcode scanner written in C++ and compile that to Wasm using Emscripten, adopting the Docker and Node.js-based approach outlined here. After a few minor teething problems, the eBay team were able to run the barcode scanner in the browser, using a Worker thread and JavaScript glue code.

The Wasm-based scanner was able to process images of the barcode at 50 Frames per Second (FPS), compared to about 1FPS in an earlier JavaScript-based scanner eBay had tested, a speed-up the team described as "astonishing".
Unfortunately, the Wasm code only successfully completed scans 60% of the time, because it wasn't using the inbuilt APIs available for the C++ code to either autofocus or provide user tap focus for the center of the scanned object. eBay's team ultimately ended up implementing three separate worker threads running the Wasm code, the open-source barcode reader ZBar, and their original JavaScript-based scanner code.

"The winning response (i.e. the first one to send a valid barcode) is sent to the main thread, and all workers are terminated... With three threads racing against each other, the success rate was indeed close to 100%."
