VRoamer Generates On-The-Fly VR Experiences While Walking Through Buildings

VRoamer is a new Microsoft Research project that generates VR worlds on-the-fly while users walk through unknown building environments. Players can wear their HMD and no longer have to rely on artificial locomotion techniques such as teleportation. They simply walk through their environment and the game is built around them. This is possible through the use of a wearable tech camera that scans the environment in front of the user and visualizes a playable virtual world. The system paints its virtual environment over real world objects such as doors. The system keeps the user safe from objects in the real world, even though those objects are hidden to the user. Transitions are done through corridors that are constructed to the available space in the user's environment. Players can open real doors to progress the game and the corridors may contain weapons, enemies, keys, etc. Objects that suddenly appear in a user's environment such as other people may become skeletons or traps.

In this paper, we present VRoamer, which enables users to walk unseen physical spaces for which VRoamer procedurally generates a virtual scene on-the-fly. Scaling to the size of office buildings, VRoamer extracts walkable areas and detects physical obstacles in real time using inside-out tracking, instantiates pre-authored virtual rooms if their sizes fit physically walkable areas or otherwise generates virtual corridors and doors that lead to undiscovered physical areas. The use of these virtual structures that connect pre-authored scenes on-the-fly allow VRoamer to (1) temporarily block users' passage, thus slowing them down while increasing VRoamer's insight into newly discovered physical areas, (2) prevent users from seeing changes beyond the current virtual scene, and (3) obfuscate the appearance of physical environments. VRoamer animates virtual objects to reflect dynamically discovered changes of the physical environment, such as people walking by or obstacles that become apparent only with closer proximity.

Nvidia Releases "Creator Ready" RTX Drivers

Earlier this week, Nvidia rolled out a set of "creator ready" drivers that are compatible with consumer GPUs, but optimized for professional applications. This level of support is typically reserved for drivers that only work with pricey Quadro GPUs, but Nvidia says they've conducted "exhaustive multi-app testing" in programs like Adobe Premiere and After Effects. Support for this driver goes all the way back to Pascal cards, and extends to Nvidia's more affordable offerings like the GTX 1050 and the more recent 1660. Perhaps even more interestingly, Nvidia claims they've worked with a number of software vendors to leverage the raytracing and machine-learning muscle their RTX cards offer. Autodesk Arnold and Unreal Engine 4, for example, now support RTX accelerated rendering, and Redcine-X Pro seemingly uses Turing's updated video processing block to decode 8K video without taxing the CPU. Meanwhile, Lightroom uses "an extensively trained convolutional neural network to provide state-of-the-art image enhancing for RAW photographs." While I haven't tested Lightroom's new features myself, in my experience, neural networks can perform small miracles when processing images. Nvidia also claims the new driver features significant performance improvements in Photoshop, Premiere, Blender Cycles, and Cinema 4D.

"Creators are constantly faced with tight deadlines and depend on having the latest hardware and creative tools to complete their projects on time, without compromising quality," said Eric Bourque, senior software development manager at Autodesk. "We're excited that NVIDIA is introducing a Creator Ready Driver program because it will bring Arnold users an even higher level of support, helping them bring their creative visions to life faster and more efficiently." The first Creator Ready Driver is now available from NVIDIA.com or GeForce Experience. From GeForce Experience, you can switch between Game Ready and Creator Ready Drivers at any time by clicking the menu (three vertical dots in the top right corner). Creator Ready Drivers are supported for Turing-based GeForce RTX, GTX and TITAN GPUs, Volta-based TITAN V, Pascal-based GeForce GTX and TITAN GPUs, and all modern Quadro GPUs.

Intel Shows Off Graphics Card Designs at GDC 2019

Intel reportedly unveiled some "early designs" of their upcoming discrete graphics cards at their GDC 2019 presentation. The graphics card in the first and 2nd slides they showed largely reassembles an Optane 905P SSD with a blower fan and a conspicuously short PCB. While the Xe's specs and performance levels are still unknown, to me, the short PCB suggests that Intel will use some kind of on-package memory with their upcoming GPU, or a relatively narrow GDDR memory bus at the very least. A shot of the back reveals a full backplate, as well as 3 DisplayPort outputs and one HDMI port. Finally, the last slide shows a card with a fan right on top of the graphics chip, which is something I haven't seen on a high-end reference card in some time.

Unfortunately, full specifications are still not yet available for Intel's upcoming graphics card. Real world performance is essentially completely unknown for now. As the year goes on, there is a good chance Intel may share some numbers given how eager the company is to make everyone aware that they have a major new product incoming.

Nvidia Skips Ampere at GTC 2019

Several news outlets seems to think Nvidia's GTC presentation was relatively longwinded and unexciting this year. The three-hour keynote reportedly featured some software announcements and a low power Jetson board, among other things, but didn't feature the 7nm Ampere GPUs many were expecting. EE Times says that the "unspoken message" at the presentation was that "Nvidia doesn't need to pre-announce a new and faster chip because it owns that software stack and channel today," and the emphasis on CUDA seemed to really drive that point home. However, in one of the more exciting parts of the presentation, Nvidia did highlight the Q2VKPT project we covered earlier this year. Nvidia's CEO seemed quite excited about the introduction of raytracing to Quake II, and they showed off some of the project's gameplay, which you can see below:

Presaging that future, Nvidia's chief scientist, Bill Dally, told reporters about a research project in optical chip-to-chip links. It targets throughput in terabits/second while drawing 2 picojoules/bit/s. In an initial implementation, 32 wavelengths will run at 12.5 Gbits/s each, with a move to 64 wavelengths doubling bandwidth in a follow-up generation. Dally predicted that copper links will start run out of gas as data rates approach 100 Gbits/s, already on many roadmaps for network switches. Progress in more power-efficient laser sources and ring resonators will enable the long-predicted shift, he said. If the future evolves as he believes, bleeding-edge GPUs may continue to skip an appearance at some Nvidia events. Attendees will have to hope that as the interconnects speed up, the keynotes don't get even longer.

Shadow of the Tomb Raider Receives RTX Treatment in Latest Patch

The latest patch for Shadow of the Tomb Raider has enabled support for real time ray tracing and NVIDIA's DLSS. To enable the features, gamers will need Window 10 update 1809 or higher, NVIDIA RTX 20- series GPU, and NVIDIA's latest drivers 419.35 and up. Nixxes announced the creation of a Beta, enabling the ability to switch back to an older version of the game, if problems arise.

We have just released the thirteenth PC patch for Shadow of the Tomb Raider, build 1.0.280. This patch focuses primarily on the release for the Nvidia's Ray-Traced Shadows and DLSS. While we expect this patch to be an improvement for everyone, if you do have trouble with this patch and prefer to stay on the old version, we have made a Beta available on Steam, Build 279, that can be used to switch back to the previous version.

Not All RTX 2080s are Created Equal

Manufacturers have had some time to stock store shelves and warehouses with Nvidia RTX laptops, but as Techspot pointed out earlier this year, the nomenclature can be very confusing. The laptop "RTX 2080," for example, doesn't have the same performance as the desktop version of RTX 2080, and there are multiple version of the "RTX 2080 Max-Q" with different levels of performance. Hardware Unboxed tested the performance difference between the various versions, which you can see in the video below:
The fact that Nvidia can cram a 545mm^2 GPU into a low-power laptop at all is remarkable, and generally speaking, the RTX chips perform well in their relatively small power envelopes. But as the video points out, be careful if you're in the market for a gaming laptop, as the actual performance level of some RTX GPUs can be difficult to discern. Discussion

NVIDIA Could Tease Next-Gen 7nm Ampere at GTC 2019

It isn’t clear whether NVIDIA will have any surprises to share at next week’s GPU Technology Conference (GTC), but some speculate the company could reveal aspects of its next-generation architecture, "Ampere," which will purportedly be built on the 7nm node. TweakTown and TechSpot suggest it could be the right time to do so, as the luster of Volta and Turing continues to wear thin. The former predicts it won’t be a gaming part, however, suggesting "a new GPU architecture tease that will succeed Volta in the HPC/DL/AI market."

For now, NVIDIA has used the Ampere name for their future 7nm GPUs. If that's the case, the Ampere GPUs would bring power efficiency improvements, higher clock rates, and perhaps higher memory bandwidth. Now would be a good time for NVIDIA to make a big announcement, considering the company just had one of the worst fiscal quarters its ever had. Consumer and investor faith in the company is slipping, especially since the adoption of RTX technology has been much slower than expected.

Nvidia's Freesync Monitor Support Tested

Nvidia recently released a driver update that adds support for Freesync monitors, but the GPU maker was quick to point out that "non-validated" displays could exhibit serious issues. However, Techspot put that claim to the test last January, and just followed up on it with a handful of new Freesync monitors from LG. Out of the 12 monitors they've tested so far, 11 have worked flawlessly, and the one that didn't only supports Freesync over HDMI, while Nvidia only supports the adaptive sync technology over Displayport.

As we said in the original article, we think it's safe to say if you purchase a new FreeSync model today that it will work fine with Nvidia GPUs. You shouldn't expect to see any graphical issues, whether you buy an LG monitor or a display from a different maker. Only the very early, older FreeSync monitors may have some issues. Thus our recommendation continues to be to select your next monitor on its merits, features and preference. If it's a FreeSync gaming monitor and you can save some money, that's great. GeForce GPU owners no longer you need to bother with G-Sync for getting proper variable refresh rate, unless that's the monitor you want for other factors as mentioned above. These results from a selection of LG monitors just reinforces that FreeSync gaming displays can and will perform perfectly.

NVIDIA: RTX GPUs, High-Refresh-Rate Monitors Can Improve Your Kill-Death Ratio

If only to convince gamers to upgrade their GPUs and displays, NVIDIA has published new data supporting the obvious idea that better hardware improves player performance in Battle Royale titles such as Fortnite and Apex Legends. Essentially, players who can manage 144 fps score significantly higher than those limited to 60 fps: the company’s graphs suggest its RTX cards can increase K/D ratio by as much as 53%, while playing on 240 Hz and 144 Hz monitors can improve K/D ratio by 34% and 51%, respectively.

NVIDIA used more than a million sample points collected via anonymous GeForce Experience data, and then analyzed the data (which means no AMD cards). Specifically, NVIDIA is looking at player performance in two popular battle royale games: PUBG and Fortnite. How do you quantify player performance? NVIDIA looked at kill/death ratio and matched that up with number of hours played per week, then finally broke that down into graphics hardware and monitor refresh rate. NVIDIA limited its analysis to 1080p, which provides for the highest refresh rates and also serves to normalize things a bit.

Nissan Will Use a Vive and HaptX Gloves to Prototype Designs

Nissan is teaming up with haptic feedback expert HaptX to create a system where designers and engineers can prototype future car designs in a virtual environment. Using HaptX gloves and what appears to be an HTC Vive, the workers can interact with mock-ups of car interiors and exteriors without having to build an expensive physical prototype for every new design. Nissan seems to be particularly invested in VR technology, as they claim to be "the first automaker in Japan to use HaptX Gloves." They also showed off a number of driver-focused AR technologies at CES last January, including a rain-parting navigation system and a holographic, animesque avatar that pops out of the dash.

It takes years between creating the first 3D model to sitting in the driver's seat of a complete physical prototype. HaptX Gloves can reduce that time from years to days, letting you grip the steering wheel, adjust the volume dial, and feel the click of the glove compartment in VR, before the first piece of steel is bent. This type of nuanced interaction allows auto designers to get a better sense of their customer’s experience. "Automakers have faced imperfect options in the design process. VR controllers are unnatural and inadequate for realistic feedback, but full-scale physical models are expensive and limited in their utility," said Jake Rubin, Founder and CEO of HaptX. "HaptX Gloves address these limitations, enabling auto designers to feel their new vehicle models throughout the design process and allowing for rapid prototyping within VR."
