Sampler Feedback was added to Microsoft DirectX early in 2020, and is supported by Intel Xe Graphics. This session will cover two distinct applications of the technology: texture space shading and streaming. The 3DMark Sampler Feedback Feature Test will be referenced to demonstrate the texture space shading mode of Sampler Feedback. The streaming mode of Sampler Feedback facilitates drawing scenes requiring hundreds of gigabytes of texture data and will benefit from the coding efficiency and performance of DirectStorage for Windows.


After this session, developers will be armed with the knowledge and tools to start using the Sampler Feedback feature with the latest Intel Xe GPUs. Intel platforms are also ready for DirectStorage for Windows, making streaming applications easier to implement and delivering improved performance as compared to existing file APIs.

Intended Audience

Developers who want to use the latest APIs to implement graphics applications.
