The GeForce Now game streaming service that Nvidia announced for the Mac last year is finally coming to Windows PCs. According to their website, the service lets you stream high-resolution games from your PC to your Mac or Windows PC that may or may not have the power to run the games natively. Starting this week, beta users of the GeForce Now Mac client will be able to install and run the Windows app. Tom Warren reports via The Verge: I got a chance to play with an early beta of the GeForce Now service on a $400 Windows PC at CES today. My biggest concerns about game streaming services are latency and internet connections, but Nvidia had the service setup using a 50mbps connection on the Wynn hotel's Wi-Fi. I didn't notice a single issue, and it honestly felt like I was playing Player Unknown's Battlegrounds directly on the cheap laptop in front of me. If I actually tried to play the game locally, it would be impossible as the game was barely rendering at all or at 2fps. Nvidia is streaming these games from seven datacenters across the US, and some located in Europe. I was playing in a Las Vegas casino from a server located in Los Angeles, and Nvidia tells me it's aiming to keep latency under 30ms for most customers. There's obviously going to be some big exceptions here, especially if you don't live near a datacenter or your internet connectivity isn't reliable. The game streaming works by dedicating a GPU to each customer, so performance and frame rates should be pretty solid. Nvidia is also importing Steam game collections into the GeForce Now service for Windows, making it even more intriguing for PC gamers who are interested in playing their collection on the go on a laptop that wouldn't normally handle such games.

Nvidia is putting a stop to the resale of bundled promotional game keys by tying them to a specific graphics card purchase, according to Ars Technica. Users will now have to redeem codes via the GeForce Experience (GFE) app, which is directly linked to third-party services like Steam and Uplay. Users must also ensure that the requisite graphics card is "installed before redemption." GFE then performs "a hardware verification step to ensure the coupon code is redeemed on the system with the qualifying GPU." From the report: Previously, retailers sent promotional game codes to customers that purchased a qualifying product. Those codes could then be redeemed on Nvidia's website, which spit out the relevant Steam, Uplay, Origin, or Microsoft Store key. Since the promotional game codes were not tied to a specific account, many users took to either gifting spare keys to friends or selling them on eBay in order to offset the cost of the graphics card purchase. [Ars Technica has updated their report with additional information:] Nvidia has confirmed that while GFE checks to ensure a user has installed a qualifying graphics card like a GTX 1070 or GTX 1080, the game itself is not permanently linked to the hardware. GFE's hardware check is based only on the wider product range, and not on a specific serial number. The company has also confirmed that the redemption process permanently adds the game to the appropriate third-party service. For example, if users redeems a promotional game key through to Steam, that game will be useable on any other device, just like normal Steam games. Users can also opt to uninstall GFE, or install a different graphics card, once the promotional code has been redeemed and still retain full ownership of the game. A full set of instructions for redeeming codes is now available on Nvidia's website.

Deathspawner writes: NVIDIA has today released a Game Ready GeForce driver that introduces its interactive screenshot tool 'Ansel.' Named after famed photographer Ansel Adams, this new tool requires a developer to integrate up to a couple hundred lines of code to give players the ability to pause their game, move around the environment, and then capture a more "artistic" image. To further that artistic value, users will have the ability to apply filters as well as capture an image in high-res 360 mode so that they can be viewed properly with a virtual-reality (VR) headset. Currently, Ansel supports only a single game -- Mirror's Edge Catalyst -- but NVIDIA promises that many more supported titles are on the way. In addition, NVIDIA has released its first ever video game via Steam that just so happens to be a VR game. The game is called VR Funhouse and is available for free via Steam but is only playable on the HTC Vive. The game consists of a virtual-reality carnival and employs many NVIDIA graphics technologies, like collision-based haptic feedback and advanced physics simulation.

Deathspawner writes: When NVIDIA announced its GeForce GTX TITAN X at GTC, no one was surprised that it'd be faster than the company's previous top-end card, the GTX 980. But what did impress many is that the company said the card would sport a staggering 12GB of VRAM. As Techgage found, pushing that 12GB is an exercise in patience — you really have to go out of your way to come even close. Additional reviews available at PC Perspective and AnandTech. The latter notes, "...from a technical perspective, the GTX Titan X and GM200 GPU represent an interesting shift in high-end GPU design goals for NVIDIA, one whose ramifications I’m not sure we fully understand yet. By building what’s essentially a bigger version of GM204, heavy on graphics and light on FP64 compute, NVIDIA has been able to drive up performance without a GM204-like increase in die size. At 601mm2 GM200 is still NVIDIA’s largest GPU to date, but by producing their purist graphics GPU in quite some time, it has allowed NVIDIA to pack more graphics horsepower than ever before into a 28nm GPU. What remains to be seen then is whether this graphics/FP32-centric design is a one-off occurrence for 28nm, or if this is the start of a permanent shift in NVIDIA GPU design."

jones_supa writes: One week after NVIDIA disabled overclocking on their GeForce 900M mobility lineup, a representative of the company has reported that NVIDIA will be bringing back the disabled feature for their overclocking enthusiasts on the mobility front. On the GeForce Forums, he writes, "We heard from many of you that you would like this feature enabled again. So, we will again be enabling overclocking in our upcoming driver release next month for those affected notebooks. If you are eager to regain this capability right away, you can also revert back to 344.75."

wiredmikey writes "NVIDIA on Saturday quietly released a driver update (version 310.90) that fixes a recently-uncovered security vulnerability in the NVIDIA Display Driver service (nvvsvc.exe). The vulnerability was disclosed on Christmas day by Peter Winter-Smith, a researcher from the U.K. According to Rapid7's HD Moore, the vulnerability allows a remote attacker with a valid domain account to gain super-user access to any desktop or laptop running the vulnerable service, and allows an attacker (or rogue user) with a low-privileged account to gain super-access to their own system. In addition to the security fix, driver version 310.90 addresses other bugs and brings performance increases for several games and applications for a number of GPUs including the GeForce 400/500/600 Series."
