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

CES is known for putting the spotlight on wacky innovations and Eufy came prepared for this year's event. The company just revealed its E20 robot vacuum, which can actually transform from a traditional robovac to a manually-controlled stick vac. This is the first time we've seen something like this. Some robovacs include additional stick vacuums, but do not transform into them.
The design seems simple. On the outside, it looks similar to competing robot vacuums from companies like Roomba. However, users can simply remove the vacuum module, which includes a motor and a filtration system, and pop it onto a stick attachment. It also comes with a handheld vacuum attachment, which works in a similar way.

 TCL has long been a proponent of using Mini LED TVs as an alternative to OLED ones, and at CES 2025 the company is introducing what it claims is the best version of the idea yet in the TCL QM6K TV. The new QD-Mini LED TV is the first of several new options in TCL's new "Precise Dimming Series," and it includes several breakthrough improvements to the display technology.
The QM6K is the first of TCL's TVs to use the company's Halo Control Technology Suite, which is the catch-all name for the various tweaks it's made to the dimming and picture quality of its Mini LEDs. That includes things like a new "Super High Energy LED chip" that TCL claims increases brightness output and light efficiency, a new "Condensed Micro Lens" that allows for even more precise control over the light that comes from a TV's LEDs and updated "Quantum Dot Technology" that helps display up to 98 percent of the DCI-P3 color gamut.

 Anker has a major presence at CES 2025, as the company has revealed a whole bunch of wild and wacky products. One such item is a newly-announced solar electric cooler, which is basically like a portable refrigerator/freezer combo.
The Anker Solix EverFrost cooler is available in three sizes, from 23L to 58L, and uses air-cooled refrigeration technology for "faster and precise cooling." To that end, Anker promises that these units cool more than 20 percent faster than rival products and allow for accurate temperature regulation from -4 degrees to 68 degrees Fahrenheit.
That's right. The temperature range is vast enough to refrigerate and freeze items. The largest model even has two independent compartments to do both at once. That's pretty handy. There could be one side for beverages and another side for those all-important ice cubes.
There are plenty of high-tech bells and whistles here. As stated before, this is a solar electric cooler. That means the detachable batteries can charge via an integrated 100W solar panel or by plugging into a standard power outlet. The batteries can also double as power banks for charging up smartphones and the like.
Anker
As for usage limits, Anker says these coolers can run for 52 hours with a single battery and up to 104 hours with two batteries. As you can see above, there's room enough for a pair of batteries. There's also a proprieta
