For example, scaling a game with a resolution of 1280 x 720 on a panel with a resolution of 3840 x 2160 should yield pure integer scaling since the dimensions of the panel represent those of the source image multiplied by three. When the dimensions of the scaled image are the same integer multiple of the original image. In what scenarios can I get full-screen pure integer scaling? This is described in more detail later in the document. We provide both options because some users might prefer NN to IS (depending on the OS and display panel resolution, the former can yield greater overall display utilization). Intel will provide options to enable both IS and NN-based scaling in the IntelĀ® Graphics Command Center. What is being implemented on the IntelĀ® Processor Graphics Gen11 in the late August 2019 driver release? Therefore, integer scaling is particularly useful for pixel art games that rely on sharp, blocky images to deliver their distinctive look. 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. Both IS and NN preserve the clarity of the original image. 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. Integer scaling (IS) is a nearest-neighbor upscaling technique that simply scales up the existing pixels by an integer (i.e., whole number) multiplier.
