The query concerns optimal data acquisition frequency from input devices, primarily mice and keyboards, measured in Hertz (Hz). A higher value represents more frequent data updates transmitted from the device to the system. For example, a 1000 Hz setting indicates that the device sends data updates 1000 times per second.
The selection of an appropriate setting impacts responsiveness and input latency. Historically, lower values were common due to technological limitations and processing power constraints. Increased processing power allows for the utilization of higher settings, potentially improving perceived input accuracy and reducing delays between physical action and on-screen reaction. The human perceptual system may detect subtle differences at higher data acquisition rates, particularly in fast-paced applications.
