Windows, macOS, and Linux use system timers to schedule tasks. The default timer resolution in Windows is typically 15.6 ms (15,600,000 ns). Even when applications request high‑resolution timers (e.g., timeBeginPeriod(1) ), the minimum achievable resolution is 1 ms (1,000,000 ns).
The software creates multiple concurrent processing threads dedicated entirely to sending click commands. By saturating a CPU core with input requests, the program ensures that the very next available OS processing window is filled with a click command.

Setting an auto clicker to nanosecond intervals comes with real risks, not just theoretical limitations. Windows, macOS, and Linux use system timers to
To understand why "nanosecond" clicking is a misnomer, we have to look at the scale of time used in computing: Millisecond (ms): nanosecond autoclicker work
