NVIDIA has introduced DLSS 4, the latest version of its real-time image upscaling technology, at CES 2025. It is coming to all RTX GPUs, including the RTX 20 series that was discontinued back in 2020, but the older models aren't getting all its features. In the new GeForce RTX 50 series models, DLSS 4 will enable Multi Frame Generation. The feature generates up to three additional frames for every traditionally rendered one and can help multiply frame rates by up to eight times more than traditional brute-force rendering. NVIDIA says the improvements brought by Multiple Frame Generation on the GeForce RTX 5090 graphics card, its new $1,999 flagship GPU arriving this month, will enable 4K 240 FPS fully ray-traced gaming. In addition, DLSS 4 represents what the company is calling the "biggest upgrade to its AI models" since the release of DLSS 2. DLSS Ray Reconstruction, DLSS Super Resolution and DLAA will now be powered by the same advanced architecture powering AI models, such as ChatGPT and Google's Gemini. The company says that translates to improved temporal stability, less ghosting and higher detail of objects in motion. A total of 75 games and apps will support DLSS 4 from day zero. When the new RTX 50 cards come out, games like Alan Wake and Cyberpunk 2077 will be updated with the ability to take advantage of the technology's Multi Frame Generation feature. More titles will be updated with support for Multi Frame in the future, including Black Myth: Wukong, while upcoming ones like Doom: The Dark Ages and Dune: Awakening will support the feature at launch.This article originally appeared on Engadget at https://www.engadget.com/computing/nvidia-dlss-4-is-coming-to-all-rtx-gpus-044835216.html?src=rss

The original ROG Flow Z13 was always a bit of an odd machine. It felt like the strange lovechild between a Surface Pro and a traditional gaming laptop. But at CES 2025, ASUS is giving the tablet a much needed refresh that includes a massive performance boost thanks to the companys updated XG Mobile graphics dock. One of the biggest departures from the previous model is that this time instead of relying on a CPU/GPU solution from Intel and NVIDIA, ASUS is going with an all-AMD configuration. The ROG Flow Z13 features up to a Ryzen AI Max+ 395 APU with unified memory that tops out at a whopping 128GB (though ASUS spec sheet suggests it actually maxes out with 32GB of RAM). Also, by using a chip with an increased emphasis on power efficiency and combining that with a larger 70Whr battery (up from 56Whr), ASUS says the Z13 should deliver improved longevity of up to 10 hours on a charge. Meanwhile, the system remains rather svelte, weighing just 2.6 pounds and measuring just half an inch thick. This means it should be an excellent choice for portable gaming and productivity. The Z13s screen is also pretty impressive, because even though its not an OLED, its Nebula Display is powered by a vivid IPS panel with a 180Hz refresh rate, up to 500 nits of brightness and 100 percent coverage of the DCI-P3 spectrum. I also appreciate that even on a system this sleek, ASUS still found room for a full-size HDMI 2.1 jack in addition to two USB 4 ports, one USB-A, 3.5mm audio and even a microSD card reader. Some other subtle updates include a redesigned keyboard with larger keycaps, a more durable PU leather cover and a much bigger touchpad. Inside, theres also a new steel vapor chamber that ASUS says outperforms traditional copper variants, while the addition of a customizable Action Key on the side of the system makes it easy to adjust display settings or summon whatever app you want. Of course, one of the coolest things about the Flow Z13s adaptability is that when you want even better performance, you can connect it to ASUS ROG XG Mobile Dock, which has also gotten a major refresh for 2025. Thats because while it retains a similar design, it now supports up to an NVIDIA RTX 5090 for a massive boost in graphics power. The other big change is that instead of relying on ASUS proprietary XG Mobile port to connect the two devices together, this time the dock uses Thunderbolt 5. The dock also has a wealth of connectivity options including both HDMI 2.1 and DisplayPort 2.1 jacks, so you can use it as a hub when stationed at a desk. Finally, its also backwards compatible with the original Z13, so owners of the previous model have another way to extend the life of their machine. Photo by Sam Rutherford/Engadget Unfortunately, ASUS has yet to provide info regarding the ROG Flow Z13s release date. However, were expecting the device to start at around $2,000 for a version with a Ryzen AI Max 390 chip or $2,200 when configured with a Ryzen AI Max+ 395 APU. Pricing for the XG Mobile dock is still to be determined, though with it sporting an RTX 5090, it will almost certainly cost a pretty penny.This article originally appeared on Engadget at https://www.engadget.com/computing/laptops/the-asus-rog-flow-z13-is-starting-to-make-more-sense-as-a-gaming-tablet-043027074.html?src=rss

There's so much AI-powered nonsense at CES that it's kind of refreshing to see a very straightforward, classic gadget like the Swippitt. It's a breadbox-sized hub that contains five battery packs that can fit into a a custom-made iPhone case. When the battery is in the case, it works like similar product, keeping your phone juiced up. The trick is that when the battery is empty, you pop your phone into the top of the box and it automatically removes the battery from the case and drops in a fresh one. Keeping our phones charged up is definitely a problem, but it's fair to ask whether Swippitt is an over-engineered (or possibly too expensive) solution. For $450 you get the Swippitt hub and five batteries, but you'll also need to purchase a separate $120 case for your iPhone. The team is making cases for the iPhone 14, 15 and 16 series and is also working on ones for Samsung as well. If you're intending this to be a family solution for multiple phones, things could get pricy fast. Nathan Ingraham for Engadget That said, there's something charming about having a little box that can just drop a fully-charged battery into your phone case in seconds. I wish you could see the inside and actually see the batteries change maybe we'll get a transparent model in the future. Naturally, there's also an app that'll let you check the status of all five batteries, whether they're in the charger or out being used. Parents can even get alerts for when their kids' phone drops below 15 percent. Probably the biggest challenge for Swippitt is keeping up with phones as they get slight tweaks and revisions every year that change their dimensions and, more importantly, their batteries. Phone batteries will surely keep getting larger and require more power to recharge, so Swippitt will have to stay on top of both case design and battery pack design. It feels like a lot to ask for a small start-up, but they've already contended with such changes Apple's addition of a dedicated camera button to the iPhone 16 series meant they had to quickly redesign the case. Nathan Ingraham for Engadget As for availability, Swippitt says it'll start shipping initial orders in April, but it expects it'll take a few months from there to get fully up to speed. And while the $450 price tag is steep, Swippitt is offering 30 percent off initial orders in January, plus you can grab a $100 off early CES discount through January 17, which considerably changes the financial equation. If you're hard on your phone's batteries and want to keep it juiced up without ever really giving it a thought, that convenience might be worth the cost.This article originally appeared on Engadget at https://www.engadget.com/mobile/the-swippit-hub-keeps-your-iphone-loaded-up-with-fresh-batteries-041320116.html?src=rss
