ReShade is a popular post-processing injector for computer games that allows users to apply various effects to improve the visuals of their games. ReShade can be used with a wide variety of games, including Red Dead Redemption 2 (RDR2).
One of the most popular uses of ReShade is to improve the frame rate of games. This can be especially useful for games that are demanding on hardware, such as RDR2. By using ReShade, users can often improve their frame rate by 10-20%, or even more in some cases.
