Description: Input lag refers to the time that elapses between a user’s action, such as pressing a key or moving the mouse, and the visible response of the system or application. This phenomenon can significantly affect the user experience across various platforms, as noticeable lag can make interaction with the device feel sluggish and unresponsive. This lag can be caused by various factors, including system load, software efficiency, hardware quality, and driver optimization. In work environments that require high precision and speed, such as graphic design or gaming, input lag can be particularly problematic, as it can affect productivity and user satisfaction. Therefore, minimizing this lag is crucial to ensure an optimal user experience, and it is an aspect that software and hardware developers must carefully consider in their products.
