SuperTiling

A graphical load-balancing scheme where two graphics cards are used to render alternate small 32x32 pixel squares in a fine-grained checkerboard pattern. This configuration increases image rendering quality, as each card processes half of the complex 3D objects in the pixel squares. SuperTiling is better optimized for most applications than Scissor Mode (where two graphics cards are used to render the top and bottom halves of the screen), since the checkerboard pattern better ensures a more even distribution of what needs to be rendered. This type of graphical operation is only

available in Radeon® CrossFiregraphics cards running Microsoft® Direct 3D® games or applications.

S-Video

Short for “Separate Video,” S-Video is a type of analog video interface that produces a higher-quality signal compared to composite video. The signal is split into two separate channels— luminance (Y) and chrominance (C). Sometimes referred to as “Y/C video” or “Y/C”, the connectors typically contain 4-pins within a single connection housing and are commonly found on consumer DVD players, VCRs, game consoles, and related devices.

Texel

Short for “texture element,” the 3D equivalent of a pixel, describing the base unit of the surface of a 3D object, such as a sphere; for a 2D object, such as a circle, the base unit is a pixel.

Texture Mapping

In computer graphics, two-dimensional textured surfaces are referred to as texture maps. Texture mapping is the process by which a two-dimensional surface gets wrapped around a three-dimensional object so that the 3D object takes on the same texture qualities. For example, if you take a 2D textured surface that looks like cloth and wrap it around a 3D sphere, the sphere will now appear to have a cloth-like surface.

Texture Preference

Texture Preference is a feature enabling the user to select the texture quality level for the surface of a 3D object. Selecting the highest quality possible will provide the most realism, although it may also have some impact on the performance of any 3D intensive application.
