The delay of ordinary wireless mouse and keyboard is slightly increased compared with that of wired devices, but it does not have a significant impact on operation in daily use. Generally speaking, the delay of the wireless mouse and keyboard is between a few milliseconds and ten milliseconds, and our reaction speed is generally more than a few hundred milliseconds, so the delay will not cause too much problem for our use.
However, if you need to perform high-precision gaming or professional image processing operations, it is recommended to use wired equipment for better response speed and accuracy.
