Unsharp masking (USM) is an image sharpening technique, often available in digital image processing software. Its name derives from the fact that the technique uses a blurred, or unsharp, negative image to create a mask of the original image. The unsharp mask is then combined with the original positive image, creating an image that is less blurry than the original Sharpening can help improve image quality in games at the native resolution (or higher) as well, especially in games where post-process anti-aliasing is used which tends to blur the image. For games without film grain, you can safely lower the 'ignore film grain' value Image sharpening. Image sharpening enhances the overall sharpness of the game to make it look more realistic. AMD and NVidia have been battling around to give their customers the best gaming experience.

One of the ways to improve it is by augmenting the contrast among different parts of the image. There are several methods for image sharpening in the spatial domain. One of the most well-known is Histogram Equalization (HE). It is based on an adjustment of the contrast by using the histogram of the input image Step 4 Hit Adjustments and move the sharpening slider from left to right to adjust the sharpening level according to your demands.
