How to use NewtonReadPerformanceTick

[PJani]

Hy i have question what is NewtonReadPerformanceTick returning, milliseconds?

And if NewtonReadPerformanceTick returns per thread?

[Julio Jerez]

you pass a callback to a timrer, and it returrns the number of ticks per calls one each of teh major systems.
It is not per thread, but you can see how mutithreadin affect the performance by seeing teh number of tick go higher or lower.
Usautly you can pass use timeGetTime or any other high resolution timer, the higher the frequecy the smother the acuracy.

the timer are called for the Main thread, so you do no need to worry about that.
