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! What’s wrong with DX11? Nothing! We at the DirectX team designed DirectX 11 to b...
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. These apps generate a list of rendering instructions (i.e. the math ...
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. The new D3D9On12 API can be found in the insider SDK in D3D9o...
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...

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. Perhaps you use a texture streaming sy...
