In the next update to Windows, D3D12 will be adding two new flags to the D3D12_HEAP_FLAG enumeration. These new flags are “impermanent” properties, which don’t affect the resulting memory itself, but rather the way in which it’s allocated. This gives app developers more control and flexibility.
D3D12 is adding two new shader stages: the Mesh Shader and the Amplification Shader. These additions will streamline the rendering pipeline, while simultaneously boosting flexibility and efficiency. In this new and improved pre-rasterization pipeline, Mesh and Amplification Shaders will optionally replace the section of the pipeline consisting of the Input Assembler as well as Vertex,

Why Feedback: A Streaming Scenario
Suppose you are shading a complicated 3D scene. The camera moves swiftly throughout the scene, causing some objects to be moved into different levels of detail. Since you need to aggressively optimize for memory, you bind resources to cope with the demand for different LODs.
In this blog post, we will preview a suite of new DirectX 12 features, including DirectX Raytracing tier 1.1, Mesh Shader, and Sampler Feedback. All these features are currently available in Windows 10 Insider Preview Builds (20H1).
Many D3D12 developers have become accustomed to managing resource state transitions and read/write hazards themselves using the ResourceBarrier API. Prior to D3D12, such details were handled internally by the driver. However, D3D12 command lists cannot provide the same deterministic state tracking as D3D10 and D3D11 device contexts.
In Windows 10 1903, DRED 1.1 provided D3D12 developers with the ability to diagnose device removed events using GPU page fault data and automatic breadcrumbs. As a result, TDR debugging pain has been greatly reduced. Hooray! Unfortunately, developers still struggle to pinpoint which specific GPU workloads triggered the error.
The DirectX Control Panel (DXCpl.exe) has dutifully given developers the ability to configure Direct3D debug settings for nearly two decades. But what started as a simple utility for controlling D3D debug output and driver type selection has struggled to keep up with modern DX12 debugging options.
We publish documents, header files, binaries, and samples to allow game developers to run their DirectX 12 games on Windows 7.
In the Windows 10 May 2019 Update, codenamed 19H1, D3D12 has added a new Motion Estimation feature to D3D12. Motion estimation is the process of determining motion vectors that describe the transformation from one 2D image to another. Motion estimation is an essential part of video encoding and can be used in frame rate conversion algorithms.
Building on our previous work with the D3D12 Translation Layer library as well as the D3D11On12 and D3D9On12 mapping layers, we’re happy to share that we are working on two new projects: OpenCL and OpenGL mapping layers to D3D12.
So, you’re a developer sold on the next-gen features in DirectX 12 Ultimate?
Look no further than this little guide!
The complete set of DirectX 12 Ultimate features will be available in the next retail version of Windows 10,
It is time for DirectX to evolve once again.
From the team that has brought PC and Console gamers the latest in graphics innovation for nearly 25 years, we are beyond pleased to bring gamers DirectX 12 Ultimate, the culmination of the best graphics technology we’ve ever introduced in an unprecedented alignment between PC and Xbox Series X.
Tomorrow (3/19) is DirectX Developer Day! Join the Microsoft DirectX team, along with partners AMD and NVIDIA, for a series of talks and demos covering the future of gaming graphics:
The New Features and Unprecedented Opportunities of DirectX 12 – Jianye Lu
The New Standard for Next Gen Games –
GDC may have been postponed, but we aren’t going to let that prevent us from bringing the next generation of graphics innovation to the world. Join us this Thursday, March 19, for a virtual DirectX Developer Day on Mixer! The Microsoft DirectX team,
If you’re a developer looking to port your game to DX12, we have good news: The D3D12 Translation Layer, a helper library for translating graphics concepts and commands from a D3D11-style domain to a D3D12-style domain, is now open source.
As an example of how to use the library, we have also opened sourced the D3D11On12 mapping layer.
We wrote this article to explain the difference between Fullscreen Exclusive and Fullscreen Optimizations. This article goes details the roll out and the benefits that come with Fullscreen Optimizations.
On Monday, Epic Games announced that DirectX 12 support is coming to Fortnite. And today, the wait is over: anyone updating to the v11.20 patch has the option to try out Fortnite’s beta DX12 path!
What does this all mean? Let’s see if we can help!
We wrote this article to explain two key terms: CPU-bound and GPU-bound. There’s some misinformation about this terms, and we’re hoping this article can help fix this problem.
Even though applications run on the CPU, many modern-day applications require a lot of GPU support.
D3D is introducing D3D9on12 with resource interop APIs and adding similar resource interop APIs to D3D11on12. With this new support, callers can now retrieve the underlying D3D12 resource from the D3D11 or D3D9 resource object even when the resource was created with D3D11 or D3D9 API.
