Latency, the delay between an input and the corresponding output, is a critical factor in user experience. Low latency is essential in digital systems, especially in fields like gaming and virtual reality. High latency could lead to user frustration and, in extreme cases, physical discomfort.
The human brain can detect latency as low as 20 milliseconds (ms), while the ideal latency for interactive systems is below 10ms. Achieving this level of performance requires optimising every stage of the ‘input-render-output’ process.
Hardware plays a crucial role in reducing latency. The input device, the display, and the system’s internal components all contribute to the total latency. For instance, a typical computer mouse has a latency of 8ms, while a standard LCD monitor adds another 10ms.
Software optimisation is equally important. Minimising the time taken to process input data can significantly reduce latency. Techniques like predictive rendering, where the system anticipates user actions, can also help.
However, reducing latency is a complex task due to the variety of factors involved. It requires a comprehensive understanding of the system’s architecture and a meticulous approach to optimisation.
The pursuit of low latency is a driving force behind technological innovation. It pushes the boundaries of what’s possible, leading to more immersive and responsive digital experiences.
