The brand new Oculus Rift S is being shown off at GDC and Ars Technica had a chance to play with it.  The new implementation is rather impressive, a single wire connects you to your PC and there are now no external cameras, instead they have been relocated to the headset itself.  From the description in the review it seems they have done so very successfully, with location tracking improving as opposed to degrading due to that change.  Your eyeballs also get an upgraded experience, with each eye having a 1280x1440 display, though as of yet Oculus have not changed to AMOLED screens.

Check it out here.

"This is out-of-the-box room scale," Oculus co-founder Nate Mitchell said as he gestured to the Oculus Rift S, the new PC-focused VR headset launching "this spring" for $399. This headset will effectively replace the standard Oculus Rift headset, which has had production all but halted to make way for the new model."

Microsoft Announces Variable Rate Shading for DirectX 12

Subject: Graphics Cards | March 19, 2019 - 08:29 PM |
Tagged: microsoft, DirectX 12, turing, nvidia

To align with the Game Developers Conference, GDC 2019, Microsoft has announced Variable Rate Shading for DirectX 12. This feature increases performance by allowing the GPU to lower its shading resolution for specific parts of the scene (without the developer doing explicit, render texture-based tricks).

An NVIDIA speech from SIGGRAPH 2018 (last August)

The feature is divided into three parts:

  • Lowering the resolution of specific draw calls (tier 1)
  • Lowering the resolution within a draw call by using an image mask (tier 2)
  • Lowering the resolution within a draw call per primitive (ex: triangle) (tier 2)

The last two points are tagged as “tier 2” because they can reduce the workload within a single draw call, which is an item of work that is sent to the GPU. A typical draw call for a 3D engine is a set of triangles (vertices and indices) paired with a material (a shader program, textures, and properties). While it is sometimes useful to lower the resolution for particularly complex draw calls that take up a lot of screen space but whose output is also relatively low detail, such as water, there are real benefits to being more granular.

The second part, an image mask, allows detail to be reduced for certain areas of the screen. This can be useful in several situations:

  • The edges of a VR field of view
  • Anywhere that will be brutalized by a blur or distortion effect
  • Objects behind some translucent overlays
  • Even negating a tier 1-optimized section to re-add quality where needed

The latter example was the one that Microsoft focused on with their blog. Unfortunately, I am struggling to figure out what specifically is going on, because the changes that I see (ex: the coral reef, fish, and dirt) don’t line up with their red/blue visualizer. The claim is that they use an edge detection algorithm to force high-frequency shading where there would be high-frequency detail.

Microsoft claims that this feature will only be available for DirectX 12. That said, NVIDIA, when Turing launched, claims that Variable Rate Shading will be available for DirectX 11, DirectX 12, Vulkan, and OpenGL. I’m not sure what’s different between Microsoft’s implementation that lets them separate it from NVIDIA’s extension.

Microsoft will have good tools support, however. They claim that their PIX for Windows performance analysis tool will support this feature on Day 1.

NVIDIA is ready to storm the server room

Subject: General Tech, Graphics Cards, Networking, Shows and Expos | March 19, 2019 - 06:16 PM |
Tagged: nvidia, t4, amazon, microsoft, NGC, Mellanox, CUDA-X, GTC, jen-hsun huang, DRIVE Constellation, ai

As part of their long list of announcements yesterday, NVIDIA revealed they are partnering with Cisco, Dell EMC, Fujitsu, Hewlett Packard Enterprise, Inspur, Lenovo and Sugon to provide servers powered by T4 Tensor Core GPUs, optimized to run their CUDA-X AI accelerators. 

t4.PNG

Those T4 GPUs have been on the market for a while but this marks the first major success for NVIDIA in the server room, with models available for purchase from those aforementioned companies.  Those who prefer other people's servers can also benefit from these new products, with Amazon and Microsoft offering Cloud based solutions.  Setting yourself up to run NVIDIA's NGC software may save a lot of money down the road, the cards sip a mere 70W of power which is rather more attractive than the consumption of a gaggle of Tesla V100s.  One might be guilty of suspecting this offers an explanation for their recent acquisition of Mellanox.

NGC software offers more than just a platform to run optimizations on, it also offers a range of templates to start off with from classification, and object detection, through sentiment analysis and most other basic starting points for training a machine.  Customers will also be able to upload their own models to share internally or, if in the mood, externally with other users and companies.  It supports existing products such as TensorFlow and PyTorch but also offers access to CUDA-X AI, which as the name suggests takes advantage of the base design of the T4 GPU to reduce the amount of time waiting for results and letting users advance designs quickly. 

memorex.PNG

If you are curious exactly what particular implementations of everyone's favourite buzzword might be, NVIDIA's DRIVE Constellation is a example after JoshTekk's own heart.  Literally an way to create open, scalable simulation for large fleets of self-driving cars to train them ... for good one hopes.  Currently the Toyota Research Institute-Advanced Development utilizes these products in the development of their next self-driving fleet, and NVIDIA obviously hopes others will follow suit.

There is not much to see from the perspective of a gamer in the short term, but considering NVIDIA's work at shifting the horsepower from the silicon you own to their own Cloud this will certainly impact the future of gaming from both a hardware and gameplay perspective.  GPUs as a Service may not be the future many of us want but this suggests it could be possible, not to mention the dirty tricks enemy AIs will be able to pull with this processing power behind them.

One might even dream that escort missions could become less of a traumatic experience!

Tagged: tempered glass, mesh, MasterBox NR600, MasterBox NR400, enclosure, cooler master, chassis, case, airflow

Cooler Master has launched a pair of new cases today with the MasterBox NR400 and the MasterBox NR600. These budget-friendly cases offer a minimalist approach with clean lines and no flashy lighting effects, and should offer good airflow with their full mesh front panels.

Cooler_Master_NR_0.jpg

The Cooler Master MasterBox NR600 is an ATX mid-tower

The MasterBox NR400 is the smaller of the two cases, supporting mini ITX and micro ATX motherboards, with the larger MasterBox NR600 offering support for standard ATX motherboards.

Cooler_Master_NR_1.jpg

Cooler Master provides this list of features for these two new NR series cases:

  • Minimalistic Mesh Design - Elegant design elements are applied to mesh for optimal thermal performance.
  • Optimal Thermal Performance – The full mesh front panel and ventilated top panel provide a high potential for thermal performance.
  • Flush Tempered Glass Side Panel – The tempered glass side panel, fastened by thumbscrews on the rear panel, keeps the surface completely flush.
  • Headset Jack – The single 4 pole headset jack features both audio and microphone capabilities simultaneously so separate jacks are not needed.
  • Graphics Card Support Up to 346mm (NR400) / 410mm (NR600) – Generous clearance space is provided to support the latest graphics cards.
  • Cable Management – High quality, longer length rubber grommets paired with generous clearance behind the motherboard offers ample room for cable management.

Cooler_Master_NR_2.jpg

"Thermal performance is at the core of the NR Series, with the combination of two pre-installed fans for intake and exhaust and the fine mesh front panel. Generous support for radiator mounting and unrestricted ventilation on the top and front panel ensure that even the most demanding components are efficiently cooled while the two USB 3.1 gen 1 ports at the top of the case provide ample connectivity for everyday use."

Cooler_Master_NR.jpg

The Cooler Master MasterBox NR400 is a smaller mATX design

The MasterBox NR400 has an MSRP of $59.99, with the NR600 at $69.99. Both cases are available for pre-sale today, though no listings have yet found their way to Amazon or Newegg at time of writing.

Google Announces Stadia at GDC 2019

Subject: General Tech | March 19, 2019 - 03:28 PM |
Tagged: google, stadia

Google Stadia, a new gaming service, was announced at the 2019 Game Developers Conference. Much like OnLive and PlayStation Now, users connect to an instance of video games running in datacenters. Because it is a conference for game developers, they also mentioned a few added features, such as directly transcoding for YouTube and allowing the audience to wait in line and jump into a streamer’s game session.

Requirements and price were not mentioned, but it will arrive sometime in 2019.

Google also mentioned that applicable games would run on Linux and the Vulkan API. Given their Android initiative, and their desire to not pay Microsoft a license fee for VMs, this makes a lot of sense. It also forces major engine developers to target and optimize Linux-focused APIs, which will be good in the long run, especially if Google starts adding GPUs from Intel and NVIDIA in the coming years. I'm not sure how much it will push Linux ports, however, because that's not really why publishers avoid the platform.

In terms of hardware, Google claims that an instance will have about 10.7 teraflops of GPU performance on an AMD platform. In terms of compute, this puts it equivalent to a GTX 1080 Ti, although AMD tends to have reduced fillrate, etc., which keeps them behind NVIDIA parts with equivalent compute performance. (Those equivalent AMD parts also tend to be significantly cheaper, and thus comparing flop to flop isn’t fair in most other circumstances.)

google-2019-stadia-controller.png

As long-time readers know, I am also very cautious about streaming services because they are about the epitome of DRM. While the content is available on other, local platforms? Not really a big deal. If a game is developed for Google’s service, and requires Google’s API, then games that leave the service, either by Google’s license ending or Google simply not wanting to host it anymore, will be just about impossible to preserve. Games are not movies or sound files that can be transcoded into another format.

Linux and Vulkan does provide a bit more confidence, but you never know what will happen when a company, with no legal (ex: the GPL) obligation to remain open, gets large enough.

It’s something that I’m still worried about, though.

The Khronos Group Releases OpenXR 0.90 (Provisional)

Tagged: Khronos, openxr

At the Games Developers Conference in San Francisco, the Khronos Group has published the first, provisional release of the augmented reality and virtual reality API: OpenXR 0.90. The goal is to allow the general public to implement it into their software so they can provide feedback (via the official forums) before it launches into 1.0.

khronos-2019-openxr-logo.png

The last time we’ve mentioned OpenXR was SIGGRAPH back in August. That event had a demo area on the show floor with the Epic Showdown VR demo, which evolved into Robo Recall. On that end, Epic plans to continue support for OpenXR, and they pride themselves as the engine that powers the original demo. Unity has also responded positively to OpenXR, but their quoted statement doesn’t make any specific promises. Microsoft and Collabora are each, separately, providing hardware implementations of the new API. Oculus plans to support the API when it reaches 1.0 status. HTC also wants to support OpenXR with the Vive, although Valve is nowhere to be seen on the list of quotes. Google is also nowhere to be seen on the list.

GTC 19: NVIDIA Announces GameWorks RTX; Unreal Engine and Unity Gain DXR Support

Subject: General Tech | March 18, 2019 - 10:00 PM |
Tagged: gameworks, unreal engine, Unity, rtx, ray tracing, nvidia, GTC 19, GTC, dxr, developers

Today at GTC NVIDIA announced GameWorks RTX and the implementation of real-time ray tracing in the upcoming Unreal Engine 4.22 and the latest version of Unity, currently in 2019.03.

NVIDIA Announces GameWorks RTX

While Pascal and non-RTX Turing support for real-time ray tracing is something of a bombshell from NVIDIA, the creation of GameWorks tools for such effects is not surprising.

“NVIDIA GameWorks RTX is a comprehensive set of tools that help developers implement real time ray-traced effects in games. GameWorks RTX is available to the developer community in open source form under the GameWorks license and includes plugins for Unreal Engine 4.22 and Unity’s 2019.03 preview release.”

NVIDIA lists these components of GameWorks RTX:

GW_RTX.PNG

  • RTX Denoiser SDK – a library that enables fast, real-time ray tracing by providing denoising techniques to lower the required ray count and samples per pixel. It includes algorithms for ray traced area light shadows, glossy reflections, ambient occlusion and diffuse global illumination.
  • Nsight for RT – a standalone developer tool that saves developers time by helping to debug and profile graphics applications built with DXR and other supported APIs.

Unreal Engine and Unity Gaining Real-Time Ray Tracing Support

DXR_GAME_ENGINES.png

And while not specific to NVIDIA hardware, news of more game engines offering integrated DXR support was also announced during the keynote:

“Unreal Engine 4.22 is available in preview now, with final release details expected in Epic’s GDC keynote on Wednesday. Starting on April 4, Unity will offer optimized, production-focused, realtime ray tracing support with a custom experimental build available on GitHub to all users with full preview access in the 2019.03 Unity release. Real-time ray tracing support from other first-party AAA game engines includes DICE/EA’s Frostbite Engine, Remedy Entertainment’s Northlight Engine and engines from Crystal Dynamics, Kingsoft, Netease and others.”

RTX may have been off to a slow start, but this will apparently be the year of real-time ray tracing after all - especially with the upcoming NVIDIA driver update adding support to the GTX 10-series and new GTX 16-series GPUs.

NVIDIA to Add Real-Time Ray Tracing Support to Pascal GPUs via April Driver Update

Tagged: unreal engine, Unity, turing, rtx, ray tracing, pascal, nvidia, geforce, GTC 19, GTC, gaming, developers

Today at GTC NVIDIA announced a few things of particular interest to gamers, including GameWorks RTX and the implementation of real-time ray tracing in upcoming versions of both Unreal Engine and Unity (we already posted the news that CRYENGINE will be supporting real-time ray tracing as well). But there is something else... NVIDIA is bringing ray tracing support to GeForce GTX graphics cards.

DXR_GPUs.png

This surprising turn means that hardware RT support won’t be limited to RTX cards after all, as the install base of NVIDIA ray-tracing GPUs “grows to tens of millions” with a simple driver update next month, adding the feature to both to previous-gen Pascal and the new Turing GTX GPUs.

How is this possible? It’s all about the programmable shaders:

“NVIDIA GeForce GTX GPUs powered by Pascal and Turing architectures will be able to take advantage of ray tracing-supported games via a driver expected in April. The new driver will enable tens of millions of GPUs for games that support real-time ray tracing, accelerating the growth of the technology and giving game developers a massive installed base.

With this driver, GeForce GTX GPUs will execute ray traced effects on shader cores. Game performance will vary based on the ray-traced effects and on the number of rays cast in the game, along with GPU model and game resolution. Games that support the Microsoft DXR and Vulkan APIs are all supported.

However, GeForce RTX GPUs, which have dedicated ray tracing cores built directly into the GPU, deliver the ultimate ray tracing experience. They provide up to 2-3x faster ray tracing performance with a more visually immersive gaming environment than GPUs without dedicated ray tracing cores.”

A very important caveat is that “2-3x faster ray tracing performance” for GeForce RTX graphics cards mentioned in the last paragraph, so expectations will need to be tempered as RT features will be less efficient running on shader cores (Pascal and Turing) than they are with dedicated cores, as demonstrated by these charts:

Apart from the new DLSS available on NVIDIA's RTX cards, it has been a very long time since we looked at anti-aliasing implementations and the effects your choice has on performance and visual quality.  You are likely familiar with the four most common implementations, dating back to AMD's MLAA and NVIDIA's FXAA which are not used in new generation games to TAA/TXAA and SMAA but when was the last time you refreshed your memory on what they actually do and how they compare.

Not only did Overclockers Club looking into those, they discuss some of the other attempted implementations as well as sampling types that lie behind these technologies.  Check out their deep dive here.

"One setting present in many if not all modern PC games that can dramatically impact performance and quality is anti-aliasing and, to be honest, I never really understood how it works. Sure we have the general idea that super-sampling is in effect running at a higher resolution and then downscaling, but then what is multi-sampling? How do post-processing methods work, like the very common FXAA and often favored SMAA?"

Crytek has released video of a new demo called Neon Noir, showcasing real-time ray tracing with a new version of CRYENGINE Total Illumination, slated for release in 2019. The big story here is that this is platform agnostic, meaning both AMD and NVIDIA (including non-RTX) graphics cards can produce the real-time lighting effects. The video was rendered in real time using an AMD Radeon RX Vega 56 (!) at 4K30, with Crytek's choice in GPU seeming to assuage fears of any meaningful performance penalty with this feature enabled (video embedded below):

“Neon Noir follows the journey of a police drone investigating a crime scene. As the drone descends into the streets of a futuristic city, illuminated by neon lights, we see its reflection accurately displayed in the windows it passes by, or scattered across the shards of a broken mirror while it emits a red and blue lighting routine that will bounce off the different surfaces utilizing CRYENGINE's advanced Total Illumination feature. Demonstrating further how ray tracing can deliver a lifelike environment, neon lights are reflected in the puddles below them, street lights flicker on wet surfaces, and windows reflect the scene opposite them accurately.”

Crytek is calling the new ray tracing features “experimental” at this time, but the implications of ray tracing tech beyond proprietary hardware and even graphics API (it works with both DirectX 12 and Vulcan) are obviously a very big deal.

crytek_demo.png

“Neon Noir was developed on a bespoke version of CRYENGINE 5.5., and the experimental ray tracing feature based on CRYENGINE’s Total Illumination used to create the demo is both API and hardware agnostic, enabling ray tracing to run on most mainstream, contemporary AMD and NVIDIA GPUs. However, the future integration of this new CRYENGINE technology will be optimized to benefit from performance enhancements delivered by the latest generation of graphics cards and supported APIs like Vulkan and DX12.”

AMD States Its CPUs Are Not Susceptible to SPOILER

Subject: Processors | March 18, 2019 - 08:38 AM |
Tagged: spoiler, speculation, spectre, rowhammer, meltdown, amd

AMD has issued a support article stating that its CPUs are not susceptible to the recently disclosed SPOILER vulnerability. Support Article PA-240 confirms initial beliefs that AMD processors were immune from this specific issue due to the different ways that AMD and Intel processors store and access data:

We are aware of the report of a new security exploit called SPOILER which can gain access to partial address information during load operations. We believe that our products are not susceptible to this issue because of our unique processor architecture. The SPOILER exploit can gain access to partial address information above address bit 11 during load operations. We believe that our products are not susceptible to this issue because AMD processors do not use partial address matches above address bit 11 when resolving load conflicts.

amd-epyc.jpg

SPOILER, one of the latest in the line of speculative execution vulnerabilities that have called into question years of processor architecture design, describes a process that can expose the mappings between virtual and physical memory. That's not a complete issue in and of itself, but it allows other attacks such as Rowhammer to be executed much more quickly and easily.

The research paper that initially disclosed SPOILER earlier this month states that Intel CPUs dating as far back as the first generation Core-series processors are affected. Intel, however, has stated that the vulnerabilities described in the paper can be avoided. The company provided a statement to PC Perspective following our initial SPOILER reporting:

Intel received notice of this research, and we expect that software can be protected against such issues by employing side channel safe software development practices. This includes avoiding control flows that are dependent on the data of interest. We likewise expect that DRAM modules mitigated against Rowhammer style attacks remain protected. Protecting our customers and their data continues to be a critical priority for us and we appreciate the efforts of the security community for their ongoing research.

We also managed to get a sneak preview of a completely different type of laptop made specifically for content creators."

Sebastian has given you a look at the triple slot EVGA GTX 1660 XC Black as well as the dual fan and dual slot MSI GTX 1660 GAMING X, both doing well in benchmarks especially when overclocked.  The new GTX 1660 does come in other shapes and sizes, like the dual slot, single fan GTX 1660 StormX OC 6G from Palit which The Guru of 3D reviewed.  Do not underestimate it because of its diminutive size, the Boost Clock is 1830MHz out of the box and with some tweaking will sit around 2070MHz and the GDDR5 pushed up to 9800MHz.

"We review a GeForce GTX 1660 that is priced spot on that 219 USD marker, the MSRP of the new non-Ti model, meet the petite Palit GeForce GTX 1660 StormX OC edition. Based on a big single fan and a small form factor you should not be fooled by its looks. It performs well on all fronts, including cooling acoustic levels."
