This sample has been retired as it either was developed for earlier generation hardware or the sample has been superseded by a newer sample with an advanced algorithm. The sample is still available for download if desired.
Onloaded Shadows is a technique by which shadow maps can be calculated asynchronously on the CPU. By using cascades, the shadow map for objects near the camera are calculated every frame on the GPU, but the shadow maps for objects in the second cascade and beyond are calculated less often on the CPU. This allows for better work balancing across the CPU and GPU.

Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
