The TressFX11 sample shows how to use AMD’s TressFX hair rendering technology for rendering and simulating hair. TressFX uses volumetric self shadowing, transparency, and antialiasing to render individual strands of realistic looking hair. It also uses the GPU to accelerate the physics simulation of each hair.

DepthBoundsTest11 shows how to use the AMD Depth Bounds Test extension, a feature of the AMD GCN architecture, to limit rendering within a specified depth bounds. By limiting what pixels are rendered, some graphics techniques can run faster because fewer pixels need to be rendered, and therefore fewer instructions executed by pixel shaders.
