## API Samples
In the Samples directory, you will find samples that attempt to break off specific features and specific usage scenarios into bite-sized chunks. For example, the ExecuteIndirect sample will show you just enough about execute indirect to get started with that feature without diving too deep into multiengine whereas the nBodyGravity sample will delve into multiengine without touching on the execute indirect feature etc. By doing this, we hope to make it easier to get started with DirectX 12.

# Direct3D 12 variable-rate shading sample
+This sample illustrates how to use variable-rate shading (VRS) to improve application performance. VRS adds the concept of subsampling, where shading can be computed at a level coarser than a pixel. For example, a group of pixels can be shaded as a single unit, and the result is then broadcast to all samples in the group. This is great for areas of the image where extra detail doesn't help—such as those behind HUD elements, transparencies, blurs (depth-of-field, motion, etc.), and optical distortions due to VR optics.
