Nightmare Echoes are variants of existing Echoes in Wuthering Waves that greatly affect how players use their Resonators. They are inherently stronger than their regular counterparts, and if you want to get the most out of your characters, getting a Nightmare Echo should be on your list of priorities.

The PS2 was an unprecedented success following the PS1, which was Sonys debut console. It reigned supreme for decades but was just recently dethroned in sales by the Switch in 2024. 2005 came near the end of the PS2s peak, but alongside it, North America got the PSP which debuted in the West a year after Japan.

Rinascita, the region introduced in Version 2.0 of Wuthering Waves, offers players a wealth of new areas to explore, Echoes to collect, and quests to complete. Some of these quests are hidden from the map, requiring players to venture out and discover them on their own.

When it comes to gaming, laptops have come a long way. Once seen as the lesser cousin to gaming PCs, todays gaming laptops pack a serious punch, offering remarkable power and portability in sleek packages. Whether youre exploring open-world RPGs, dominating multiplayer arenas or creating content on the side, modern gaming laptops deliver performance that can rival many desktop rigs, with the added bonus of being able to game wherever you want.One of the biggest advantages of a laptop is its flexibility. You dont need to worry about bulky setups or being tethered to one spot. Plus, with features like displays with high refresh rates, powerful GPUs and cutting-edge processors, these machines are more than capable of handling AAA titles, eSports and even VR gaming. Many laptops now come equipped with RGB-lit keyboards, advanced cooling systems and next-gen SSD storage to keep up with your gaming needs, too. Weve tested a number of the latest gaming laptops to see which are worth your money. What to look for in a gaming laptop Price Your laptop buying journey starts and ends with the amount of money you're willing to spend. No surprise there. The good news: There are plenty of options for gamers of every budget. In particular, we're seeing some great entry-level PC gaming choices under $1,000, like Dell's G15 lineup. A cheap gaming laptop in this price range will definitely feel a bit flimsier than pricier models, and they'll likely skimp on RAM, storage and overall power. But most cheaper laptops should be able to handle the majority of video games running at 1080p at 60 frames per second, which is the bare minimum you'd want from any system. Things get interesting when you start looking at the best gaming laptops in the mid-range space, with prices at $1,000 and higher. At that point, you'll start finding PCs like the ASUS Zephyrus ROG G14, one of our favorite gaming notebooks. In general, you can look forward to far better build quality than budget gaming laptops (metal cases!), improved graphics power and enough RAM and storage space to handle the most demanding games. These are the gaming machines we'd recommend for most people, as they'll keep you gaming and working for years before you need to worry about an upgrade. If you're willing to spend around $1,800 or more, you can start considering more premium options like Razer's Blade, which is on-par with some of the best gaming PCs. Expect impeccably polished cases, the fastest hardware on the market, and ridiculously thin designs. The sky's the limit here: Alienware's uber customizable Area 51m is an enormous beast that can cost up to $4,700. Few people need a machine that high-end, but if you're a gamer with extra cash to burn, it may be worth taking a close look at some of these pricier systems. CPU and GPU The answer to this question used to be relatively simple: Just get an Intel chip with an NVIDIA GPU. But over the last few years AMD has stepped up its game with its Ryzen notebook processors, which are better suited for juggling multiple tasks at once (like streaming to Twitch while blasting fools in Fortnite). Intel responded with its impressive 12th and 13th-gen chips, but its nice to have decent Ryzen AMD alternatives available, especially since theyre often cheaper than comparable Intel models. When it comes to video cards, though, AMD is still catching up. Its Radeon RX 6000M GPU has been a fantastic performer in notebooks like ASUSs ROG Strix G15, but it lags behind NVIDIA when it comes to newer features like ray tracing. (Were still waiting to test AMDs new Radeon 7000 series mobile graphics.) At the very least, a Radeon-powered notebook can approach the general gaming performance of the NVIDIA RTX 3070 and 3080 GPUs. If you want to future-proof your purchase, or youre just eager to see how much better ray tracing can make your games look, youre probably better off with an NVIDIA video card. Theyre in far more systems, and its clear that they have better optimized ray tracing technology. NVIDIA GeForce RTX GPUs also feature the companys DLSS technology, which uses AI to upscale games to higher resolutions. Thatll let you play a game like Destiny 2 in 4K with faster frame rates. Thats useful if youre trying to take advantage of a high refresh rate monitor. Youll still find plenty of laptops with NVIDIAs older RTX 30-series GPUs these days, and theyll still give you tremendous performance. But to be safe, its probably worth opting for the newer RTX 40-series systems, since they support the newer DLSS 3 technology and offer a wealth of performance upgrades. (If youre looking out for the best deals, you can probably find some killer RTX 3070 laptops out there.) The entry-level RTX 4050 is a solid start, but wed suggest going for a 4060 or 4070 if youre aiming to maximize your framerates on faster screens. The RTX 4080 and RTX 4090 are both incredibly powerful, but they typically make systems far too expensive for most users. Its worth noting that NVIDIAs mobile graphics cards arent directly comparable to its more powerful desktop hardware. PC makers can also tweak voltages to make gaming performance better in a thinner case. Basically, these laptops may not be desktop replacements dont be surprised if you see notebooks that perform very differently, even if theyre all equipped with the same GPU. Screen and refresh rate Screen size is a good place to start when judging gaming notebooks. In general, 15-inch laptops will be the best balance of immersion and portability, while larger 17-inch models are heftier, but naturally give you more screen real estate. There are some 13-inch gaming notebooks, like the Razer Blade Stealth, but paradoxically you'll often end up paying more for those than slightly larger 15-inch options. Were also seeing plenty of 14-inch options, like the Zephyrus G14 and Blade 14, which are generally beefier than 13-inch laptops while still being relatively portable. But these days, there is plenty to consider beyond screen size. For one: refresh rates. Most monitors refresh their screens vertically 60 times per second, or at 60Hz. That's a standard in use since black and white NTSC TVs. But over the past few years, displays have evolved considerably. Now, 120Hz 1080p screens are the bare minimum you'd want in any gaming notebook and there are faster 144Hz, 240Hz and even 360Hz panels. All of this is in the service of one thing: making everything on your display look as smooth as possible. For games, higher refresh rates also help eliminate screen tearing and other artifacts that could get in the way of your frag fest. And for everything else, it just leads to a better viewing experience. Even scrolling a web page on a 120Hz or faster monitor is starkly different from a 60Hz screen. Instead of seeing a jittery wall of text and pictures, everything moves seamlessly, as if you're unwinding a glossy paper magazine. Going beyond 120Hz makes gameplay look even more responsive, which to some players gives them a slight advantage. Steve Dent/Engadget Not to make things more complicated, but you should also keep an eye out for NVIDIA's G-SYNC and AMD's FreeSync. They're both adaptive sync technologies that can match your screen's refresh rate with the framerate of your game. That also helps to reduce screen tearing and make gameplay smoother. Consider them nice bonuses on top of one of the best gaming monitors with a high refresh rate; they're not necessary, but they can still offer a slight visual improvement. See Also: Best Laptops for 2023 Best Cheap Windows Laptops Best 2-in-1 Laptops for 2023 Best Chromebooks Best Laptops for College Students One more thing: Most of these suggestions are related to LCD screens, not OLEDs. While OLED makes a phenomenal choice for TVs, it's a bit more complicated when it comes to gaming laptops. They're mostly limited to 60Hz, though some models offer 90Hz. Still, you wont see the smoothness of a 120Hz or 144Hz screen. OLEDs also typically come as 4K or 3.5K panels you'll need a ton of GPU power to run games natively at that resolution. They look incredible, with the best black levels and contrast on the market, but we think most gamers would be better off with an LCD. Devindra Hardawar/Engadget Other things to remember when buying a gaming laptop: Get at least 16GB of RAM. And if you're planning to do a ton of multitasking while streaming, 32GB is worth considering. Storage is still a huge concern. These days, I'd recommend aiming for a 1TB M.2 SSD, which should be enough space to juggle a few large titles like Destiny 2. (If you can afford the jump to a 2TB SSD though, just do it.) Some laptops also have room for standard SATA hard drives, which are far cheaper than M.2's and can hold more data. Get your hands on a system before you buy it. I'd recommend snagging the best gaming laptop for you from a retailer with a simple return policy, like Amazon or Best Buy. If you don't like it, you can always ship it back easily. Don't forget about accessories! For the best performance, you'll need a good mouse, keyboard and a headset these are some of the best gaming accessories for gaming PCs and laptops. How we test gaming laptops We review gaming laptops with the same amount of rigor as we approach traditional notebooks. We test build quality by checking cases for any undesirable flexible spots, as well as the strength of screen hinges during furious typing and Halo Infinite sessions. We benchmark every gaming notebook with PCMark 10, a variety of 3DMark tests, Cinebench and Geekbench. We also use NVIDIAs Frameview app to measure the average framerates in Cyberpunk 2077, Halo Infinite and other titles. For media creation, we transcode a 4K movie clip into 1080p using Handbrakes CPU and GPU encoding options. Displays are tested under indoor and outdoor lighting with productivity apps, video playback and gameplay. We also try to stress the full refresh rate of every gaming notebooks screen by benchmarking Halo Infinite, Overwatch 2 and other titles. Laptop speakers are judged by how well they can play back music, movies and the occasional game session with detail and clarity, and without any obvious distortion. When it comes to battery life, we see how long gaming systems last with a mixture of real-world productivity apps and gameplay, and we also test with PCMark 10s Modern office battery test. In addition, were judging the quality of a machines keyboard with typing tests as well as relative accuracy and comfort during extended gaming sessions. Best gaming laptops for 2025 Other gaming laptops weve tested Framework Laptop 16 We were eager to test the Framework Laptop 16 since it promised both modular customizability and a decent amount of gaming power. But while we appreciated just how repairable and upgradeable it is, its actual gaming performance was middling for its high price. You could always buy it without the additional GPU, but that makes it more of a daily workhorse than a gaming system. MSI Stealth Studio 14 On a brighter note, we were pleased to see MSI return to form with the Stealth Studio 14, which is far faster and more attractive than the previous model. Razer Blade 16 and 18 We were amazed to see a genuine 4K/1080p native screen in the Razer Blade 16, but its far too expensive and impractical, even for such a pricey brand. Similarly, we found the Razer Blade 18 to be both oversized and overpriced.This article originally appeared on Engadget at https://www.engadget.com/computing/laptops/best-gaming-laptops-172033838.html?src=rss

The CES keynote will never be the same.This is my 12th CES, so there aren't many things that surprise me at this point, at least in terms of press conferences. All of the big companies used to try to one-up each other (celebrity appearances were the main method, although it's not as common now). However, the venue itself has now become the battleground for CES addresses.This week, Delta was the first company to host a CES press conference, or as the emcee called it, "a show," at the Sphere in Las Vegas. You've likely heard about the high-tech venue at this point, which usually hosts immersive concerts rather than trade show events. Debuting in 2023, the "multi-sensory experience" is known for having both the interior and exterior draped in LED displays and offering 4D effects like wind and smells.Three different credentials were required to attend the event in the venue which holds 18,600 people, one of which required a special trip to obtain. Once inside, Delta had various installations to celebrate its 100th anniversary and lines for the company's merchandise were absurdly long. People even skipped the Lenny Kravitz performance at the end to queue up for those goods.You could hear every realistic boom and pop.Billy Steele for EngadgetThere was also food that may have been similar to what the airline serves in-flight, and snacks that you'd expect on a Delta trip, like Biscoff cookies. Of course, the company stacked the audience with employees and guests, plus it trotted out a couple of celebrities Viola Davis and Tom Brady which I saw as a throwback to the CES keynote days of old. Then there was the full-blown concert at the end: Lenny Kravitz with a full band. This gave the attendees the experience of coming to a concert at Sphere, where U2, Dead & Company, Phish and more have performed in the past.But, as you might expect, the most interesting aspect of the whole thing is how Delta took advantage of the Sphere's 4D capabilities. Video of each speaker was projected on the interior of the venue set on various backdrops that transformed the hall into spaces ranging from a dome to an observation deck and an airplane cabin. Several times during CEO Ed Bastian's address there were interactions with planes where the seats rumbled and blown air provided a sense of flying, complete with directional, immersive audio. There was also a cameo by Uber CEO Dara Khosrowshahi where an Uber Eats delivery arrived at the stage with a hazelnut-flavored coffee for Bastian and those aromas were wafted into the audience.Perhaps the most dazzling aspect of the whole "show" was the end, where cockpit video of a plane landing was projected on the interior of the Sphere. And when the plane landed, everyone's seats rumbled just liked they do when you hit the tarmac in real life. This was quickly followed by my first indoor fireworks show, designed to cap off Delta's 100th anniversary. I will say the immersive audio of the Sphere really enhanced this, and I doubt I'll experience anything like it again. I feel confident I'll never see indoor fireworks unless I return to this very venue.Seats rumbled just like they would in real life.Billy Steele for EngadgetOf course, there was news. It wouldn't be a CES press event without some. Delta announced its AI Concierge, an assistant inside the Fly Delta app that the company built to relieve travel stress. The airline first announced the concierge concept at CES 2020, but now it's working to make it a real thing that anticipates travel needs. Beginning this year, customers will be able to interact with Delta Concierge via text or voice. Eventually, the platform will be able to do things like hail a Joby VTOL aircraft to drop you off at the airport to avoid traffic.The AI tech can recognize both departure and arrival needs, including arranging a rideshare pickup for transport to a hotel. At the airport, you won't have to go through a TSA checkpoint, you just keep walking to your gate thanks to PreCheck Touchless ID. If you're wearing AR glasses during your trip, wayfinding then becomes a breeze with the travel assistant lighting your path. And once you're on the plane, the Delta Concierge will eventually automatically connect you to Delta Sync Wi-Fi and the seatback entertainment system to display customized info and content recs just for you.Delta's event was easily the most impressive CES presentation I've attended. And I've been to press events where each person had a PC and a VR headset at their seat. I don't know that any other company will invest what the airline did in the hosting and production this week, but it was immediately apparent that the bar had been raised, and that a ballroom at Mandalay Bay or The Venetian will no longer suffice if you're looking to make a lasting impression.Lenny Kravitz closed the show, and he'll close this post.
