Abstract

The power consumption of processor-based devices may be reduced by reducing the consumption of power during graphics processing. In some embodiments, the precision of pixel shading in parts of images where artifacts are less objectionable may be reduced. For example, in areas the user is not directly looking at, precision may be reduced to save power. At the same time, because a person is not focusing on those regions, even if usually perceptible artifacts occur because of the reduced precision, an overall pleasing depiction may be achieved.
