Alternate Frame Rendering

Alternate Frame Rendering (AFR) is a technique of graphics rendering in personal computers which combines the work output of two or more graphics processing units (GPU) for a single monitor, in order to improve image quality, or to accelerate the rendering performance. The technique is that one graphics processing unit computes all the odd video frames, the other renders the even frames. This technique is useful for generating 3D video sequences in real time, improving or filtering textured polygons and performing other computationally intensive tasks, typically associated with computer gaming, CAD and 3D modeling.

One disadvantage of AFR is a defect known as micro stuttering.

Famous quotes containing the words alternate, frame and/or rendering:

    Germany is a queer country: one can’t regard it dispassionately. I alternate between hating it thoroughly, stick, stock and stone, and yearning over it fit to break my heart. I can’t help feeling it a young and adorable country—adolescent—with the faults of adolescence.
    —D.H. (David Herbert)

    Human life itself may be almost pure chaos, but the work of the artist—the only thing he’s good for—is to take these handfuls of confusion and disparate things, things that seem to be irreconcilable, and put them together in a frame to give them some kind of shape and meaning. Even if it’s only his view of a meaning. That’s what he’s for—to give his view of life.
    Katherine Anne Porter (1890–1980)

    By rendering the labor of one, the property of the other, they cherish pride, luxury, and vanity on one side; on the other, vice and servility, or hatred and revolt.
    James Madison (1751–1836)
