raise-timer-frequency Chrome flag

--raise-timer-frequency

What does --raise-timer-frequency do?

Raise the timer interrupt frequency in all Chrome processes, for experimental purposes. This feature is needed because as of Windows 10 2004 the scheduling effects of changing the timer interrupt frequency are not global, and this lets us prove/disprove whether this matters. See https://crbug.com/1128917
