Didn't Windows 8 move to a tickless kernel in which that setting no longer has any effect? EDIT: Yes: http://arstechnica.com/information-technology/2012/10/bet

- gpderetta 10y agoTickless by itself doesn't guarantee that the system won't be woken up periodically by an application timer. It simply guarantees that the system won't wake up needlessly if there are no timers to serve. Timer coalescing, which I believe Windows also implement, does help by both setting a minium resolution to timer frequency and making sure that timers wake up in batches. edit: spelling
- ygra 10y agoSure, but it gets rid of the overhead that reducing system timer resolution to 1 ms has which was there even if there weren't any timers running.
