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.
