This mod for Red Dead Redemption disables shadows in the game, which can significantly improve performance, increasing FPS by 10-15 frames per second. This is especially useful for owners of low-end PCs who have difficulty maintaining a playable framerate.
However, it is worth noting that at some points in the game shadows may appear briefly, such as at night in certain interiors such as the saloon, or during certain cutscenes.
