Stretched resolution, often abbreviated as “stretched res”, is a display setting in which the game is rendered at a lower resolution than the native resolution of the monitor. This results in a wider field of view, which can be beneficial in some games, particularly first-person shooters.
There are several benefits to using stretched res. The wider field of view can make it easier to see enemies and objects in the game world, and it can also improve reaction times. Additionally, stretched res can reduce input lag, which can give players a competitive advantage.
