Bolt Graphics announces Zeus, a completely new GPU design for high performance workloads including rendering, HPC, and gaming. Zeus addresses performance, efficiency, and functionality limitations with legacy GPUs.

Zeus is orders of magnitude faster than any other GPU in key workloads. Users can gain 10x in rendering performance, 6x in FP64 HPC workload performance, and 300x in electromagnetic wave simulations. Users running these types of demanding workloads need access to large amounts of memory. Bolt brings expandable memory to GPUs, for the first time, which allows users to increase their memory up to 384 GB in a PCIe card, and up to 2.25 TB per Zeus in a 2U server. A rack of Zeus 2U servers can be configured with up to 180 TB of memory, 8x larger than legacy GPUs.

It is no secret that NVIDIA's RTX 50-series launch was welcomed with a mixed reception. On one hand, DLSS 4 with Multi-Frame Generation has allowed for obscene jumps in performance, much to the dismay of purists who would rather do away with AI-powered wizardry. A recent YouTube video has detailed what the RTX 5090 is capable of in Cyberpunk 2077 with Path Tracing at 4K, both with and without the controversial AI features. With DLSS set to performance mode and 4x frame generation (three generated frames), the RTX 5090 managed around 280 FPS. Pretty good, especially when considering the perfectly acceptable latency of around 52 ms, albeit with occasional spikes.

Turning DLSS to quality, the frame rate drops to around 230 FPS, with latency continuing to hover around 50 ms. Interestingly, with frame generation set to 3x or even 2x, the difference in latency was borderline negligible between the two, right around 44 ms or so. However, the FPS takes a massive nosedive when frame generation is turned off entirely. With DLSS set to quality mode and FG turned off, the RTX 5090 barely managed around 70 FPS in the game. Taking things a step further, the presenter turned off DLSS as well, resulting in the RTX 5090 struggling to hit 30 FPS in the game, with latency spiking to 70 ms. Clearly, DLSS 4 and MFG allows for an incredible uplift in performance with minimal artefacting, at least in Cyberpunk 2077 unless one really looks for it.

More than 600 games and applications feature RTX technologies, and each week new games integrating NVIDIA DLSS, NVIDIA Reflex and advanced ray-traced effects are released or announced, delivering the definitive PC experience for GeForce RTX players. This week, Indiana Jones and the Great Circle and Marvel Rivals launch with DLSS 3, Path of Exile 2 enters Early Access with day-one support for DLSS Super Resolution, and the Delta Force PC Global Open Beta kicks-off, also with day-one DLSS Super Resolution support. On December 9th, Forza Motorsport's next update introduces support for immersive Ray-Traced Global Illumination lighting. And in the near future, Warhammer 40,000: Space Marine 2's next update introduces support for DLSS 3 Frame Generation.

Indiana Jones and the Great Circle Launching With DLSS 3 & Ray Tracing
Uncover one of history's greatest mysteries in Indiana Jones and the Great Circle on December 6th with the game's Digital Premium Edition Advanced Access launch, followed by its general release on December 9th. Step into the shoes of Indiana Jones and embark on a single-player, narrative-driven journey that spans the globe during the height of the legendary archaeologist's career. From the hallowed halls of the Vatican and the sunken temples of Sukhothai to the pyramids of Egypt and the snowy peaks of the Himalayas.

Many gamers have been skeptical of the recently announced Sony PS5 Pro since the day it was announced, largely due to the high price and the perceived lack of meaningful improvements. It seemed to many as though the PS5 Pro was simply a meaningless mid-cycle cash-grab with a few extra features tacked onto the top, however, it looks like Sony and its development partners have put in the work to make the PS5 Pro experience fresh and worthwhile. According to a new post on the official PlayStation Blog, the new console will launch with at least 50 confirmed "Enhanced" games.

What exactly Sony means by Enhanced is rather nebulous, since many of the Enhanced games for the PS5 Pro have a mishmash of different Pro features. For example, Resident Evil Village gets the full 120 FPS treatment, while Horizon Forbidden West only gets a bump up to 4K at 60 FPS. Stellar Blade, on the other hand, only gets an FPS boost to 80 FPS or 50 FPS at 4K. It's likely that, like Stellar Blade, all the titles aiming for higher refresh rates on the PS5 Pro are using some mix of PSSR, dedicated AI acceleration, and traditional rasterization rendering techniques to achieve the increased frame rates. Both The Last of Us Part I and The Last of Us II Remastered will run at 60 FPS on the PS5 Pro, but they will render at 1440p and use PSSR to upscale to 4K output.

A GZDOOM community mod called "DOOM II: Ray Traced" has done the unthinkable—added path-traced lighting, shadows, and reflections to DOOM II. The mod uses high-resolution voxel models and other game assets from the Voxel DOOM Project, which replaces the game's 2D sprites as fully-fledged 3D models. Pretty much all of the game's textures also see an improvement. Where "DOOM II: Ray Traced" comes to light is its path-traced lighting, which uses ray tracing hardware of modern GPUs—nothing is pre-baked. The mod also supports NVIDIA DLSS 3 Frame Generation and AMD FSR 3.0 Frame Generation, to help step up performance. A gameplay video sees a GeForce RTX 4080 break a sweat rendering it at 4K. And to think the original DOOM II could run on an 80386—a processor simpler than a single NVIDIA CUDA core.

Microsoft has filed for a new and even potentially groundbreaking patent that could transform the way ray tracing graphics are processed, especially when video memory (VRAM) is scarce. The patent proposes a technique to minimize the memory footprint of ray tracing graphics, tackling the escalating concerns about the growing memory demands for ray tracing and path tracing. The innovation outlined in Microsoft's patent employs a dynamic level of detail (LOD) approach to adaptively modify the quality of ray tracing effects based on accessible resources. The patent portrays the ray tracing pipeline as an acceleration structure that can be streamlined using this LOD system. The cornerstone of this optimization is a residency map that aligns with a bounding volume hierarchy of objects. The graphics processing system can then utilize this map to ascertain the suitable quality level for objects at any given moment. This methodology enables a more reasonable allocation of resources, guaranteeing that the most crucial objects receive the highest quality rendering. At the same time, less important elements can be rendered at lower quality to conserve memory.

Microsoft's patent could have far-reaching ramifications for the design and performance of upcoming GPUs. By implementing this novel LOD system, GPUs with more modest VRAM capacities, such as those with 8 GB, could provide ray tracing performance on par with higher-end models boasting larger memory buffers, given enough compute capacity. This advancement could pave the way for more budget-friendly GPUs that still deliver adequate ray tracing capabilities, making the technology more accessible. Moreover, the adaptive nature of the LOD system could contribute to a more reliable performance across diverse scenarios, as the GPU would be capable of adjusting to the available resources in real time. Microsoft's patent could emerge as a game-changer in the realm of GPU design and performance, and we are now waiting to see if any real-world implementations appear.

Over 500 RTX games and applications have revolutionized how people game and create with ray tracing, NVIDIA DLSS and AI-powered technologies. Today, we're unveiling even more RTX games that will deliver the definitive PC experience for GeForce RTX gamers. At GDC 2024, we're announcing several new exciting integrations of cutting-edge RTX tech! In Black Myth: Wukong and NARAKA: BLADEPOINT, we're working with our partners to incorporate Full Ray Tracing and NVIDIA DLSS 3.5.

In Portal with RTX, our free, fully ray-traced reimaging of Valve's classic game, DLSS 3.5 with Ray Reconstruction and RTX IO are now available, further upgrading its technology, graphics and image quality. Diablo IV's ray tracing update arrives March 26th. Star Wars Outlaws will launch with DLSS 3 and ray-traced effects. The First Berserker: Khazan will launch with DLSS 3. And Sengoku Destiny introduced support for DLSS 3 earlier this week.

This week, Alan Wake 2 launches with incredible fully ray-traced graphics, accelerated and enhanced by NVIDIA DLSS 3.5's complete suite of AI-powered technologies. GeForce RTX 40 Series gamers will receive the definitive day-one experience: frame rates are multiplied by an average of 4.5X at 4K, ray tracing is even more immersive thanks to Ray Reconstruction, and Reflex makes gameplay even more responsive. Additionally, gamers can soon enable DLSS in Ikonei Island: An Earthlock Adventure, and Shadows of Doubt, two highly rated indie games.

These new DLSS integrations follow last week's DLSS launches, which saw NARAKA: BLADEPOINT, Slender: The Arrival, and Warhammer: Vermintide 2 introduce support for DLSS 3, and HOT WHEELS UNLEASHED 2 - Turbocharged and AirportSim release with DLSS 2.

Hot on the heels of news that DLSS 3.5 Ray Reconstruction can be made to work with DLAA (DLSS at native resolution) using a DLSS-modding utility, we're coming across yet another hack. This one gets you to use DLSS 3.5 Ray Reconstruction on Cyberpunk Phantom Liberty without the need for Path Tracing, and using the game's regular ray tracing technology. Path tracing is very hardware intensive feature, and in our testing, we've only been able to get playable frame-rates at 4K Ultra HD using the two fastest GPUs in the market, the RTX 4090 and RTX 4080. A user on Reddit discovered how to get Phantom Liberty to use regular ray tracing with Ray Reconstruction. We don't know who the original author of this hack is, but it was re-posted to Reddit by Daemoni73. Here are the steps:

• Launch Cyberpunk 2077, enable Ray Tracing and DLSS Super Resolution (in other words apply your preferable settings).
• Exit the game and go to your %LOCALAPPDATA%\CD Projekt Red\Cyberpunk 2077 and open the UserSettings.json file.
• Search for "DLSS_D", set the "value" and "default_value" from "false" to "true".
• Save the config file and set it as "read only".
• Launch the game and play with Ray Tracing and DLSS Ray Reconstruction.

We're excited to announce that Unreal Engine 5.3 is now available. This release brings numerous wide-ranging improvements as we continue to expand UE5's functionality and potential for game developers and creators across industries. As well as enhancements to core rendering, developer iteration, and virtual production toolsets, we're introducing Experimental new rendering, animation, and simulation features to give you the opportunity to test extended creative workflows inside UE5—reducing the need to round-trip with external applications.

Refinements to core UE5 rendering features
With this release, we've continued to refine all core UE5 rendering features to address our ongoing goal of making it easier for developers to leverage them at higher quality in games running at 60 FPS on next-gen consoles; the improvements also offer higher-quality results and enhanced performance for linear content creators. Specifically, Nanite has faster performance for masked materials, including foliage, and can represent a greater range of surfaces due to the new Explicit Tangents option, while Lumen with Hardware Ray Tracing has expanded capabilities that include multiple reflection bounces, and delivers faster performance on consoles. Other areas with notable advancements include Virtual Shadow Maps (VSM)—which is now Production-Ready—Temporal Super Resolution (TSR), Hair Grooms, Path Tracing, and Substrate.

Yesterday, Epic Games released a preview version of Unreal Engine 5.3—users can now try out the latest batch of improvements, as well as some new features. Epic's blurb Lumen boasts that their software engineers have refined "the workflows and capabilities of core features"—namely Nanite, and Path Tracing. Optimizations have resulted in "more control over performance" and overall better-looking visuals. Epic's own Fortnite, Layers of Fear (Bloober Team) and Remnant 2 (Gunfire Games) are the only currently released games running on Unreal Engine 5. Epic first showcased this technology back in 2020, with plenty of game development studios signing up to use it—but they have been slow in adapting to the feature-rich engine. In Remnant 2's case, Gunfire chose to not implement Lumen at launch.

Newly introduced experimental features include an upgraded particle rendering system—users are granted access to tool that can "create volumetrics such as smoke and fire directly inside Unreal." Epic's notes also mention that a Skeletal Editor has been added, for in-engine character weight and skinning work. Preview version 5.3 grants full support for Orthographic Rendering—useful in the fields of "architecture plus manufacturing visualizations, and stylistic games projects." Users will also see improvements in the Panel Cloth Editor and ML Cloth simulation system.

Intel's software engineers are working on path-traced light simulation and conducting neural graphics research, as documented in a recent company news article, with an ambition to create a more efficient solution for integrated graphics cards. The company's Graphics Research Organization is set to present their path-traced optimizations at SIGGRAPH 2023. Their papers have been showcased at recent EGSR and HPG events. The team is aiming to get iGPUs running path-tracing in real time, by reducing the number of calculations required to simulate light bounces.

The article covers three different techniques, all designed to improve GPU performance: "Across the process of path tracing, the research presented in these papers demonstrates improvements in efficiency in path tracing's main building blocks, namely ray tracing, shading, and sampling. These are important components to make photorealistic rendering with path tracing available on more affordable GPUs, such as Intel Arc GPUs, and a step toward real-time performance on integrated GPUs." Although there is an emphasis on in-house products in the article, Intel's "open source-first mindset" hints that their R&D could be shared with others—NVIDIA and AMD are likely still struggling to make ray tracing practical on their modest graphics card models.

CD Projekt RED has released the new Patch v1.63 for Cyberpunk 2077 which includes several quest, open world, UI, visual, as well as PC-and console-specific improvements and fixes, as it is rolling out on PC, PlayStation 5, and Xbox Series X/S. While there are plenty of changes, PC users will be glad that it improves performance of DLSS Frame Generation on AMD CPUs, which had been hit by stuttering issues. The Cyberpunk 2077 Patch v1.63 also fixes visual color issues with DLSS and Path Tracing.

The new patch also fixes Photo Mode issues, as well as a crash issue when using Razer Chroma. There are plenty of other quest, open world, miscellaneous, console-specific and REDmod fixes, which you can check out it the full release notes.

A Half Life 2 modder, Igor Zdrowowicz, has managed to integrate path tracing into the game - with striking results, even at an early stage in development. His project - codenamed "HL2RTX" - has been in-progress for a handful of months, and the modder has managed to integrate a ray tracing system into Valve's classic shooter (sort of) via NVIDIA's RTX Remix SDK. That package has become open source only very recently, so Zdrowowicz stated that a Portal RTX-derived binary was the tool of choice.

NVIDIA's Lightspeed Studios has already created an impressive RTX conversion of Valve's fan favorite puzzle-platform game Portal (2007), and modders have been poring over the underlying technology and update technique processes. A number of old favorites, running on past iterations of the Source Engine (DirectX 8 and 9), are getting the amateur mod community sprucing up treatment. It is posited that Zdrowowicz will have an easier time with his current conversion project, thanks to an official release of NVIDIA's RTX Remix toolkit (albeit in early access).

CD Projekt Red has now officially released the long-awaited patch for Cyberpunk 2077, bringing RT: Overdrive mode with Path Tracing technology preview, and other improvements. The new patch adds a Ray Tracing Overdrive and Path Tracing presets, which have to be manually enabled. Of course, the Ray Tracing: Overdrive Mode is only supported on the NVIDIA RTX 40 series graphics cards, and it will work on the RTX 3090 graphics card, although it is only limited to 1080p resolution.

The new patch also adds an option to enable Path Tracing for Photo Mode, and adds support for NVIDIA DLAA, which is NVIDIA's AI-based anti-aliasing mode meant to improve image quality. To not make it all about NVIDIA, CD Projekt Red also added support for Intel XeSS 1.1, and some minor benchmark improvements. Unfortunately, and surprisingly, the new patch does not bring any expected gameplay improvements, which will probably come at a later date in a separate patch.

CD PROJEKT RED's Cyberpunk 2077 is already one of the most technologically advanced games available, using several ray tracing techniques to render its neon-illuminated environments and vast Night City visuals at incredible levels of detail. On April 11th, a new Cyberpunk 2077 update will hit the streets, featuring the technology preview of the Ray Tracing: Overdrive Mode, which enhances the game's already-amazing visuals with full ray tracing, otherwise known as path tracing.

Full ray tracing accurately simulates light throughout an entire scene. It is used by visual effects artists to create film and TV graphics that are indistinguishable from reality, but until the arrival of GeForce RTX GPUs with RT Cores, and the AI-powered acceleration of NVIDIA DLSS, real-time video game full ray tracing was impossible because it's extremely GPU intensive.

In an interview done by PCWorld's Gordon Ung at GDC 2023, CD Projekt Red's VP and Global Art Director, Jakub "Kuba" Knapik, and NVIDIA's Senior Developer Technology Engineer, Pawel Kozlowski, shed a bit more light about the upcoming Cyberpunk 2077 Path Tracing update and what it brings to the game as well as what kind of hardware will you need to run it.

In case you missed it earlier, both CD Projekt RED and NVIDIA did talk about the RTX Path Tracing Overdrive Mode for Cyberpunk 2077, which will launch on April 11th. This will be a part of the Cyberpunk 2077 Update 1.62, which should bring additional gameplay improvements as well. It is worth to note that Path Tracing will be introduced to the game as a "technology preview," Jakub notes, as the developer is implementing this technology with NVIDIA and it is still a work in progress.

As promised and detailed earlier, NVIDIA has now released the first SDK for Path Tracing. Path Tracing, which should accurately re-create physics of all light sources in a scene, has been around and we already had a chance to see it in some demos like Quake RTX and Portal RTX, but now, thanks to some previously available NVIDIA tools and features, it could be finally coming to more games and not just tech demos.

According to NVIDIA, the thing that makes Path Tracing possible now, and more accessible to developers, is the combination of previously available NVIDIA technologies, as well as some new ones, including the new performance multiplier in DLSS 3, called the DLSS Frame Generation. The DLSS Frame Generation, working on GeForce 40 series cards and using the Optical Flow Accelerator, is what made real-time path tracing possible. The RTX Path Tracing SDK, according to NVIDIA, should re-create the physics of all light sources in a scene in order to reproduce what the eye sees in real life, and allows to build a reference path traces to ensure that lighting during production is true to life, while accelerating the iteration process; or build high-quality photo modes for RT-capable GPUs or real-time, ultra-quality modes that take advantage of the Ada Lovelace architecture.
