Microsoft has quietly rolled out two updates to its DirectX Agility SDK, and developers are already finding reasons to celebrate. The 1.717-preview release brings Shader Execution Reordering (SER) and Cooperative Vectors to the table, while the 1.616-retail update introduces Opacity Micromaps (OMM) and D3D12 Tiled Resource Tier 4 support. Together, they promise smoother and more efficient ray tracing, as well as improved resource handling. In 1.717-preview, the arrival of Cooperative Vectors means that vector and matrix operations, essential for AI-driven effects, now enjoy dedicated hardware acceleration. Instead of performing complex calculations on the CPU, developers can offload these tasks to the GPU, potentially unlocking richer neural rendering techniques in real time. Additionally, SER provides ray tracing pipelines with a helpful feature: it reorganizes the order in which shader threads execute, reducing wasted cycles caused by thread divergence.

Early internal tests show up to a 2× performance boost in path-traced scenes when SER is enabled. The preview also updates Direct3D's video encoder with a HEVC Reference List extension for longer-term reference frames, a two-pass low-resolution first encode, and built-in PSNR metrics so creators can see exactly how crisp their output really is. The 1.616-retail SDK centers on Opacity Micromaps, a feature designed to handle alpha-tested geometry, such as foliage or chain-link fences, without firing off expensive AnyHit shader calls. With OMM, supported GPUs intelligently skip unnecessary work, and Microsoft's numbers suggest a speedup of as much as 2.3x in path-traced scenes. For example, one NVIDIA demo increased from approximately 55 FPS to around 90 FPS simply by enabling OMM. Today, only NVIDIA's RTX cards have driver-level support for these micromaps, but AMD and Intel are preparing their own updates for the coming months. That same 1.616-retail release also unlocks D3D12 Tiled Resource Tier 4, finally lifting the restriction on packed mipmaps in texture arrays. This means finer-grained texture streaming, less wasted memory, and more creative freedom in writing shader code. NVIDIA has confirmed its support for this tier, Intel's drivers are already shipping, and AMD is aiming to release compatible drivers by early June 2025.

Microsoft's DirectX Raytracing (DXR) 1.2 announcement at GDC 2025 introduces two technical innovations that address fundamental ray tracing performance bottlenecks. Opacity micromaps (OMM) reduce the computational overhead in alpha-tested geometry by storing pre-computed opacity data, eliminating redundant ray-geometry intersection tests. Shader execution reordering (SER) tackles the inherent GPU inefficiency caused by incoherent ray behavior by dynamically grouping shader invocations with similar execution paths, minimizing thread divergence that has historically plagued ray tracing workloads. The real-world implications extend beyond Microsoft's claimed 2.3x OMM and 2x SER performance improvements. Both techniques are shifting development from brute-force computational approaches toward more intelligent resource management. Notably, both features require specific hardware support.

Hardware vendors' implementation timelines remain undefined despite NVIDIA's announced support across RTX GPUs, raising questions about broader ecosystem adoption rates. Microsoft's Shader Model 6.9 introduces cooperative vectors. This hardware acceleration architecture drastically improves matrix computation performance, enabling a 10x speedup in neural texture compression while reducing memory footprint by up to 75% compared to traditional methods. It bridges the gap between conventional rendering and neural rendering, with Intel, AMD, and NVIDIA already demonstrating implementations that combine path tracing with neural denoising algorithms, potentially making computationally intensive graphics accessible on mid-range consumer hardware by late 2025. While the technical merit of these advancements is clear, the April 2025 preview release timeline for the Agility SDK means developers face at least several months before these features can be meaningfully implemented in production environments.

NVIDIA unveiled its RTX Mega Geometry technology during their recent CES 2025 presentation, coinciding with the introduction of various new RTX branches. At the time, Team Green mentioned that Remedy Entertainment would be upgrading their Northlight Engine with RTX Mega Geometry technology. Last week, Digital Foundry published their early impressions of an enhanced version of Alan Wake 2, outlining "clear and measurable" improvements; especially with previous-gen GeForce RTX gaming hardware—in particular, on an RTX 4060 GPU. NVIDIA has released version 9.0 of their OptiX SDK—signalling a wider distribution of the Mega Geometry tech to game development and visualization houses. This new API, for building clusters, is advertised as being able to: "dramatically speed up BVH builds of large meshes."

Late last week, NVIDIA updated its Neural Texture Compression (NTC) toolkit BETA. RTXNTC version 0.5.0's quick start guide outlines the fundamental functions of Team Green's AI-enhanced image compression technology: "(an) algorithm designed to compress all PBR textures used for a single material together. It works best when the texture channels are correlated with each other, for example, detail in the albedo texture corresponds to detail in the normal texture. Up to 16 texture channels can be compressed into one NTC texture set. Typical PBR materials have 9-10 channels: 3x albedo, 3x normal, metalness, roughness, ambient occlusion, opacity."

New GeForce RTX 5090 and RTX 5080 GPUs - built on the NVIDIA Blackwell architecture - are now available to power generative AI content creation and accelerate creative performance. GeForce RTX 5090 and RTX 5080 GPUs feature fifth-generation Tensor Cores with support for FP4, reducing the VRAM requirements to run generative AI models while doubling performance. For example, Black Forest Labs' FLUX models - available on Hugging Face this week - at FP4 precision require less than 10 GB of VRAM, compared with over 23 GB at FP16. With a GeForce RTX 5090 GPU, the FLUX.1 [dev] model can generate images in just over five seconds, compared with 15 seconds on FP16 or 10 seconds on FP8 on a GeForce RTX 4090 GPU.

GeForce RTX 50 Series GPUs also come equipped with ninth-generation encoders and sixth-generation decoders that add support for 4:2:2 and increase encoding quality for HEVC and AV1. Fourth-generation RT Cores paired with DLSS 4 provide creators with super-smooth 3D rendering viewports. The GeForce RTX 5090 GPU includes 32 GB of ultra-fast GDDR7 memory and 1,792 GB/sec of total memory bandwidth - a 77% bandwidth increase over the GeForce RTX 4090 GPU. It also includes three encoders and two decoders, reducing export times by a third compared with the prior generation.

AMD today released the FidelityFX SDK 1.1 to the public through its GPUOpen initiative. This update includes the source code to FSR 3.1, which should make it easier for game developers to understand the technology, and integrate it with their games. FSR 3.1 requires an AMD Radeon RX 5000 series (or later) GPU, or an NVIDIA GeForce RTX 20-series (or later) GPU, although the company recommends at least an RX 6000 series or RTX 30-series GPU, regardless of model. You get the full upscaling and frame-generation capabilities of FSR 3.1 on all supported GPUs, across AMD and NVIDIA, which is the main pull for the tech, as the rival DLSS 3 Frame Generation technology only works on RTX 40-series (or later) GPUs.

AMD FSR 3.1 builds on top of FSR 3 by introducing updates to the upscaler. If you recall, the star attraction with FSR 3 has been frame-generation, but the underlying upscaling tech had been carried over from FSR 2.2. FSR 3.1 introduces some much-needed updates to the quality of upscaling, and introduces new upscaler quality presets, including a native AA mode analogous to NVIDIA's DLAA. These increases in upscaler quality lets you trade in quality for performance better. You can find all the resources you need on FSR 3.1 here.

AMD today released its first drivers to implement Microsoft's DirectX Agility SDK version 1.613, which introduces the new DirectX 12 Work Graphs 1.0 API. AMD has extensively worked on implementing the new technology, which among other things, significantly reduces the CPU's role in most common shader graphics workloads, and improve GPU shader thread saturation, as the GPU waits less on the CPU's share of shader workloads. The new AMD Software Adrenalin 23.40.14.01 drivers are off the main driver update channel, and is intended for developers and enthusiasts to start exploring GPU Work Graphs. GPU Upload Heaps, and certain features of Shader Model 6.8 on supported AMD Radeon GPUs. There are some known issues with the driver specific to AMD's implementation of GPU Work Graphs, and the latest version of the Agility SDK in general, which are listed below.

Microsoft's DirectX department is scheduled to show off several innovations at this month's Game Developers Conference (GDC), although a late February preview has already spilled their DirectSR Super Resolution API's beans. Today, retail support for Shader Model 6.8 and Work Graphs has been introduced with an updated version of the company's Agility Software Development Kit. Program manager, Joshua Tucker, stated that these technologies will be showcased on-stage at GDC 2024—Shader Model 6.8 arrives with a "host of new features for shader developers, including Start Vertex/Instance Location, Wave Size Range, and Expanded Comparison Sampling." A linked supplementary article—D3D12 Work Graphs—provides an in-depth look into the cutting-edge API's underpinnings, best consumed if you have an hour or two to spare.

Tucker summarized the Work Graphs API: "(it) utilizes the full potential of your GPU. It's not just an upgrade to the existing models, but a whole new paradigm that enables more efficient, flexible, and creative game development. With Work Graphs, you can generate and schedule GPU work on the fly, without relying on the host. This means you can achieve higher performance, lower latency, and greater scalability for your games with tasks such as culling, binning, chaining of compute work, and much more." AMD and NVIDIA are offering driver support on day one. Team Red has discussed the launch of "Microsoft DirectX 12 Work Graphs 1.0 API" in a GPUOpen blog—they confirm that "a deep dive" into the API will happen during their Advanced Graphics Summit presentation. NVIDIA's Wessam Bahnassi has also discussed the significance of Work Graphs—check out his "Advancing GPU-driven rendering" article. Graham Wihlidal—of Epic Games—is excited about the latest development: "we have been advocating for something like this for a number of years, and it is very exciting to finally see the release of Work Graphs."

Microsoft has just announced that their new DirectSR Super Resolution API for DirectX will provide a unified interface for developers to implement super resolution in their games. This means that game studios no longer have to choose between DLSS, FSR, XeSS, or spend additional resources to implement, bug-test and support multiple upscalers. For gamers this is huge news, too, because they will be able to run upscaling in all DirectSR games—no matter the hardware they own. While AMD FSR and Intel XeSS run on all GPUs from all vendors, NVIDIA DLSS is exclusive to Team Green's hardware. With their post, Microsoft also confirms that DirectSR will not replace FSR/DLSS/XeSS with a new upscaler by Microsoft, rather that it builds on existing technologies that are already available, unifying access to them.

While we have to wait until March 21 for more details to be revealed at GDC 2024, Microsoft's Joshua Tucker stated in a blog post: "We're thrilled to announce DirectSR, our new API designed in partnership with GPU hardware vendors to enable seamless integration of Super Resolution (SR) into the next generation of games. Super Resolution is a cutting-edge technique that increases the resolution and visual quality in games. DirectSR is the missing link developers have been waiting for when approaching SR integration, providing a smoother, more efficient experience that scales across hardware. This API enables multi-vendor SR through a common set of inputs and outputs, allowing a single code path to activate a variety of solutions including NVIDIA DLSS Super Resolution, AMD FidelityFX Super Resolution, and Intel XeSS. DirectSR will be available soon in the Agility SDK as a public preview, which will enable developers to test it out and provide feedback. Don't miss our DirectX State of the Union at GDC to catch a sneak peek at how DirectSR can be used with your games!"

Today, The Khronos Group, an open consortium of industry-leading companies creating advanced interoperability standards, announced the latest roadmap milestone for Vulkan, the cross-platform 3D graphics and compute API.

We are happy to share that our AMD FidelityFX Software Development Kit (SDK) is now available for download!

What is the AMD FidelityFX SDK?
The AMD FidelityFX SDK is our new and easy to integrate solution for developers looking to include AMD FidelityFX technologies into their games without any of the hassle of complicated porting procedures. In a nutshell, it is AMD FidelityFX graphics middleware.

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).

AMD has published an exciting development for its Radeon Open Compute Ecosystem (ROCm) users today. Now, ROCm is coming to the Windows operating system, and the company has extended ROCm support for consumer graphics cards instead of only supporting professional-grade GPUs. This development milestone is essential for making AMD's GPU family more competent with NVIDIA and its CUDA-accelerated GPUs. For those unaware, AMD ROCm is a software stack designed for GPU programming. Similarly to NVIDIA's CUDA, ROCm is designed for AMD GPUs and was historically limited to Linux-based OSes and GFX9, CDNA, and professional-grade RDNA GPUs.

However, according to documents obtained by Tom's Hardware (which are behind a login wall), AMD has brought support for ROCm to Radeon RX 6900 XT, Radeon RX 6600, and R9 Fury GPU. What is interesting is not the inclusion of RX 6900 XT and RX 6600 but the support for R9 Fury, an eight-year-old graphics card. Also, what is interesting is that out of these three GPUs, only R9 Fury has full ROCm support, the RX 6900 XT has HIP SDK support, and RX 6600 has only HIP runtime support. And to make matters even more complicated, the consumer-grade R9 Fury GPU has full ROCm support only on Linux and not Windows. The reason for this strange selection of support has yet to be discovered. However, it is a step in the right direction, as AMD has yet to enable more functionality on Windows and more consumer GPUs to compete with NVIDIA.

AMD today announced the AMD Alveo MA35D media accelerator featuring two 5 nm, ASIC-based video processing units (VPUs) supporting the AV1 compression standard and purpose-built to power a new era of live interactive streaming services at scale. With over 70% of the global video market being dominated by live content, a new class of low-latency, high-volume interactive streaming applications are emerging such as watch parties, live shopping, online auctions, and social streaming.

The Alveo MA35D media accelerator delivers the high channel density, with up to 32x 1080p60 streams per card, power efficiency and ultra-low-latency performance critical to reducing the skyrocketing infrastructure costs now required for scaling such compute intensive content delivery. Compared to the previous generation Alveo U30 media accelerator, the Alveo MA35D delivers up to 4x higher channel density, 4x max lower latency in 4K and 1.8x greater compression efficiency to achieve the same VMAF score—a common video quality metric.

Microsoft has implemented two new features into its DirectX 12 API - GPU Upload Heaps and Non-Normalized sampling have been added via the latest Agility SDK 1.710.0 preview, and the former looks to be the more intriguing of the pair. The SDK preview is only accessible to developers at the present time, since its official introduction on Friday 31 March. Support has also been initiated via the latest graphics drivers issued by NVIDIA, Intel, and AMD. The Microsoft team has this to say about the preview version of GPU upload heaps feature in DirectX 12: "Historically a GPU's VRAM was inaccessible to the CPU, forcing programs to have to copy large amounts of data to the GPU via the PCI bus. Most modern GPUs have introduced VRAM resizable base address register (BAR) enabling Windows to manage the GPU VRAM in WDDM 2.0 or later."

They continue to describe how the update allows the CPU to gain access to the pool of VRAM on the connected graphics card: "With the VRAM being managed by Windows, D3D now exposes the heap memory access directly to the CPU! This allows both the CPU and GPU to directly access the memory simultaneously, removing the need to copy data from the CPU to the GPU increasing performance in certain scenarios." This GPU optimization could offer many benefits in the context of computer games, since memory requirements continue to grow in line with an increase in visual sophistication and complexity.

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.
