Simulating the streaking and smearing that cameras capture when objects or the viewpoint move quickly.
Motion blur in games mimics the way real cameras and human eyes perceive rapid movement. When an object moves quickly across the frame or the camera pans fast, the result is a directional smearing of the image along the movement vector. There are two main types: camera motion blur, which blurs the entire scene when the camera rotates or moves, and per-object motion blur, which blurs individual fast-moving objects like a swinging sword or speeding car. Well-implemented motion blur adds fluidity and cinematic quality, especially at lower frame rates where it masks the gaps between frames. Poorly implemented motion blur, particularly excessive camera blur, is one of the most disabled settings in PC gaming because it can cause nausea and obscure gameplay information.
Example
Racing games like Forza Motorsport use per-object motion blur masterfully, with cars becoming streaks at high speed while the track remains sharp, perfectly conveying the sense of velocity. The Last of Us Part II uses subtle motion blur to maintain its cinematic feel during combat without obscuring gameplay. On the flip side, many PC players immediately disable camera motion blur in games like Call of Duty because it makes fast mouse movements feel smeared and disorienting.
Why it matters
Motion blur is one of the most polarizing graphics settings because its value depends entirely on context. For cinematic single-player games at 30fps, it can be essential for smooth-looking movement. For competitive shooters at 144fps, it is visual noise that hides information. Understanding the difference between good and bad motion blur explains why it is a setting worth customizing rather than a feature to blanket enable or disable.
