Here I have found something about the default timer.

As I know from apps we wrote in MS VC++ for WinNT 4.0 the default timer resolution of windows is 10 ms.
From the article above you can see LV uses 1 ms.

If I understand correctly, this setting came about in the bad old days of Windows 3.1, when by default the timer resolution was 55 ms. This slow speed was sufficient for most UI purposes and helped avoid loading down the system--an important consideration if you were doing lots of interrupt-driven DAQ operations at the same time. If you really needed a finer resolution, you could uncheck this box to get as low as (but not guaranteed) 1 ms timer resolution.

Nowadays, LabVIEW uses a 1 ms timer resolution on Win32 platforms by default, so this setting is less important than it used to be.
