Offscreen Memory An area of memory used to preload images so that they can be quickly drawn to the screen. Offscreen memory refers to all of the remaining video memory not taken up by the front buffer, which holds the contents of the display screen currently visible. OpenGL® Short for "Open Graphics Library," this is an industry standard for crossplatform 3D graphics development. It consists of a large number of functions that can be called upon in various programs, such as games, CAD, and virtual-reality systems, to produce complex 3D objects from simpler, more "primitive" building blocks.

OpenGL®
Short for “Open Graphics Library,” this is an industry standard for cross-
platform 3D graphics development. It consists of a large number of
functions that can be called upon in various programs, such as games,

ATI Overdrive maximizes the performance of the GPU by dynamically
altering its speed to an optimal level depending on usage. An on-chip
thermal sensor constantly monitors the temperature of the GPU, allowing
for maximum clock speed to be maintained while avoiding overheating.
