This sample demonstrates an optimized FFT that uses compute shaders and Shared Local Memory (SLM) to improve performance by reducing memory bandwidth.Two FFT techniques are discussed. The first is UAV and operates by ping-ponging data repeatedly between Unordered Access Views (UAVs). SLM (Shared Local Memory) is the second technique and is a more memory-bandwidth-efficient method, showing...
Initially shown at SIGGRAPH 2014, Intel's Asteroids code sample uses the Microsoft DirectX* 12 graphics API to render a scene of 50,000 fully dynamic and unique asteroids in two modes: maximum performance and maximum power saving. The application can switch between using the DirectX 11 and DirectX 12 APIs at the tap of a button. Get the sample here!
This article introduces a new implementation of the effect called adaptive screen space ambient occlusion (ASSAO), which is specially designed to scale from low-power devices and scenarios up to high-end desktops at high resolutions, all under one implementation with a uniform look, settings, and quality that is equal to the industry standard.
GPU Detect is a short graphics code sample demonstrates a way to detect the primary graphics hardware present in a system (including the 6th Generation Intel® Core™ processor family).
This code sample extends our state of the art BC7 Texture compressor with high-quality ETC1 and ASTC compression to the fast ISPC texture compression.
This article details an algorithm and associated sample code for software occlusion culling which is available for download. The technique divides scene objects into occluders and occludees and culls occludees based on a depth comparison with the occluders that are software rasterized to the depth buffer. The sample code uses frustum culling and is optimized with Streaming SIMD Extensions (SSE)...

Today any review of a new processor whether it’s used in a desktop computer, a laptop, a tablet or a phone will contain lots of information about how efficient it is and the new technologies that have been used to achieve this performance. Operating system developers spend large amounts of time optimizing improve efficiency and extend battery life, but what can be done by someone who is designing...
The conservative morphological anti-aliasing 2.0 (CMAA2) algorithm is a significant update of the original
