A rendering tier defines a level of graphics hardware capability and performance for a device that runs a WPF application. The features of the graphics hardware that most impact the rendering tier levels are:
Video RAM The amount of video memory on the graphics hardware determines the size and number of buffers that can be used for compositing graphics.
Pixel Shader A pixel shader is a graphics processing function that calculates effects on a per-pixel basis. Depending on the resolution of the displayed graphics, there could be several million pixels that need to be processed for each display frame.
Vertex Shader A vertex shader is a graphics processing function that performs mathematical operations on the vertex data of the object.
Multitexture Support Multitexture support refers to the ability to apply two or more distinct textures during a blending operation on a 3D graphics object. The degree of multitexture support is determined by the number of multitexture units on the graphics hardware.
The pixel shader, vertex shader, and multitexture features are used to define specific DirectX version levels, which, in turn, are used to define the different rendering tiers in WPF. For a full description of the rendering tiers, see Graphics Rendering Tiers.
