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:

  • 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.

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

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.

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:

Crytek's Neon Noir is a Platform Agnostic Real-Time Ray Tracing Demo

Subject: General Tech | March 18, 2019 - 09:03 AM |
Tagged: vulkan, RX Vega 56, rtx, ray tracing, radeon, nvidia, Neon Noir, dx12, demo, crytek, CRYENGINE, amd

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.

“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.”

Forget the GTX 1660 Ti, let's start speculating about the other GTX 1660

Today is the day that the GTX 1660 Ti moves from rumour to fact as the NDA is finally over and we can share our results! Sebastian's testing compared the overclocked and slightly above base price MSI GTX 1660 Ti GAMING X against the interestingly shaped EVGA GTX 1660 Ti XC Black.  Performance-wise, the rumours were fairly accurate, the card offers comparable performance to the 1070 Ti, and at at ~$280 price point it is certainly less expensive but still shows evidence of the upwards trend in price for GPUs.

If you are interested in other models, take a peek at The Guru of 3D who reviewed not one or two, but four different 1660 Ti's.  From the tiny little Palit StormX model pictured below through MSI's dual fan VENTUS XS and Gaming X to the full sized ASUS ROG STRIX with three fans you have a fair number of charts to go through!

"We have four new reviews to present today. NVIDIA is launching the 279 USD GeForce GTX 1660 Ti. We've talked about it a lot, it is the more affordable offering, Turing GPU based, yet stripped from RT and tensor functionality."

The TU116 GPU and First Look at Cards from MSI and EVGA

NVIDIA is introducing the GTX 1660 Ti today, a card build from the ground up to take advantage of the new Turing architecture but without real-time ray tracing capabilities. It seems like the logical next step for NVIDIA as gamers eager for a current-generation replacement to the popular GTX 1060, and who may have been disappointed with the launch of the RTX 2060 because it was priced $100 above the 1060 6GB, now have something a lot closer to a true replacement in the GTX 1660 Ti.

There is more to the story of course, and we are still talking about a “Ti” part and not a vanilla GTX 1660, which presumably will be coming at some point down the road; but this new card should make an immediate impact. Is it fair to say that the GTX 1660 Ti the true successor to the GTX 1060 that we might have assumed the RTX 2060 to be? Perhaps. And is the $279 price tag a good value? We will endeavor to find out here.

RTX: Off

It has been a rocky start for RTX, and while some might say that releasing GTX cards after the fact represents back-peddling from NVIDIA, consider the possibility that the 2019 roadmap always had space for new GTX cards. Real-time ray tracing does not make sense below a certain performance threshold, and it was pretty clear with the launch of the RTX 2060 that DLSS was the only legitimate option for ray tracing at acceptable frame rates. DLSS itself has been maligned of late based on a questions about visual quality, which NVIDIA has now addressed in a recent blog post. There is clearly a lot invested in DLSS, and regardless of your stance on the technology NVIDIA is going to continue working on it and releasing updates to improve performance and visual quality in games.

As its “GTX” designation denotes, the GeForce GTX 1660 Ti does not include the RT and Tensor Cores that are found in GeForce RTX graphics cards. In order to deliver the Turing architecture to the sub-$300 graphics segment, we must be very thoughtful about the types and numbers of cores we use in the GPU: adding dedicated cores to accelerate Ray Tracing and AI doesn’t make sense unless you can first achieve a certain level of rendering performance. As a result, we chose to focus the GTX 1660 Ti’s cores exclusively on graphics rendering in order to achieve the best balance of performance, power, and cost.

If the RTX 2060 is the real-time ray tracing threshold, then it's pretty obvious that any card that NVIDIA released this year below that performance (and price) level would not carry RTX branding. And here we are with the next card, still based on the latest Turing architecture but with an all-new GPU that has no ray tracing support in hardware. There is nothing fused off here or disabled in software with TU116, and the considerable reduction in die size from the TU106 reflects this.

It's an Epic post-apocalyptic GPU Exodus

The Guru of 3D took over two dozen cards on the Metro, with a focus on the DX12 render path with DX-R support which does make the NVIDIA results a bit more interesting for now.  If you are looking to play at 1080p with every bell and whistle on, you can scrape by on a GTX 1080 or Vega 56 but you should really consider bumping that to an RTX 2070 or Vega 64.  For 1440p gamers the new Radeon VII is capable of providing a good experience but you are far better off with an RTX 2080 or better. 

At 4k, well, even the RTX 2080 Ti can barely make 50fps, with the rest of the pack reaching 40fps at best.  As to the effects of DLSS and ray tracing on the visual quality and overall performance? Read on to see for yourself.

Slow light, testing ray tracing performance with Port Royal

Subject: Graphics Cards | January 14, 2019 - 02:23 PM |
Tagged: 3dmark, port royal, ray tracing

3D Mark recently released an inexpensive update to their benchmarking suite to let you test your ray tracing performance; you can grab Port Royal for a few dollars from Steam.  As there has been limited time to use the benchmark as well as a small sample of GPUs which can properly run it, it has not yet made it into most benchmarking suites.  Bjorn3D took the time to install it on a decent system and tested the performance of the Titan and the five RTX cards available on the market. 

As you can see, it is quite the punishing test, not even NVIDIA's flagship card can maintain 60fps.

"3DMark is finally updated with its newest benchmark designed specifically to test real time ray tracing performance. The benchmark we are looking at today is Port Royal, it is the first really good repeatable benchmark I have seen available that tests new real time ray tracing features."

[H]ard|OCP have been spending a lot of time with Battlefield V, determining the effect of enabling ray tracing on performance.  In their latest look, they compare the effect of running the game on an i9-9700K running at 4.6GHz versus an i7-7700K at 5GHz.  Their results are quite clear, when testing they saw a performance difference between 1-1.5 fps; well within the margin of error. 

When it comes to BFV, your CPU is not the limiter on your performance.

"We have been doing some deep dives into playing Battlefield V 64-person multiplayer lately and testing what exactly the cost of using NVIDIA Ray Tracing is in terms of framerate performance using new NVIDIA RTX 2070 and RTX 2080 cards. We did get questioned on using a 5GHz overclocked 7700K instead of the suggested CPU that EA recommends."

NVIDIA Announces the GeForce RTX 2060 for Next Gen Gaming

Subject: Graphics Cards | January 7, 2019 - 01:59 AM |
Tagged: video card, RTX 2060, rtx, ray tracing, nvidia, graphics, gpu, geforce, ces 2019, CES

On stage at an event tonight at CES 2019, NVIDIA CEO Jensen Huang made it offical: the RTX 2060 exists and will be available this month. The card is priced at $349, and is based on the same Turing architecture as the rest of the RTX family.

geforce-rtx-2060-2.jpg

The RTX 2060 was announced with 6GB of GDDR6 memory, and like its bigger siblings the RTX 2060 offers ray tracing support (with 240 Tensor Cores onboard), and NVIDIA targets 60 FPS performance with ray tracing enabled in Battlefield V:

"The RTX 2060 is 60 percent faster on current titles than the prior-generation GTX 1060, NVIDIA’s most popular GPU, and beats the gameplay of the GeForce GTX 1070 Ti. With Turing’s RT Cores and Tensor Cores, it can run Battlefield V with ray tracing at 60 frames per second."

geforce-rtx-2060-1.jpg

That 60% increase comes from benchmarks the company ran using 2560x1440 resolution, and the RTX 2060 is targeting resolutions from the mainstream 1920x1080 up to 2560x1440, though with performance between a GTX 1070 and 1080 the RTX 2060 could very well support 3840x2160 gaming at medium-to-high settings as well.

geforce-rtx-2060-3.jpg

The official launch of the RTX 2060 is January 15 from add-in partners, as well as a Founders Edition card from NVIDIA beginning on that date. NVIDIA is also launching a new bundle deal. Qualifying RTX 2060 purchasers, either as a standalone card or as part of a desktop including the RTX 2060, can choose to receive either Battlefield V or the upcoming Anthem for free.

Stay tuned for more details on the GeForce RTX 2060 soon.
