Earlier this month, Intel
confirmed on Twitter that its Gen11 graphics will add support for integer scaling. Now the chip giant published some more information about how this feature works, you can read it
over here. This feature is primarily for pixel art games.
Integer scaling (IS) is a nearest-neighbor upscaling technique that simply scales up the existing pixels by an integer (i.e., whole number) multiplier. Nearest-neighbor (NN) interpolation works by filling in the missing color values in the upscaled image with that of the coordinate-mapped nearest source pixel value. Both IS and NN preserve the clarity of the original image. In contrast, traditional upscaling algorithms, such as bilinear or bicubic interpolation, result in blurry upscaled images because they employ interpolation techniques that smooth out the transition from one pixel to another. Therefore, integer scaling is particularly useful for pixel art games that rely on sharp, blocky images to deliver their distinctive look.
Integer scaling will be added as part of the late August 2019 driver update for Intel Graphics Gen11.
