Can anyone please explain to me why some programmers use the "QueryPerformanceCounter()" in their render function. I know roughly its a high resolution timer but how and why do they use it? Thank you very much for replying.

the call the timer-functions (regardless what timer, it just must

(for example to determine the magic fps-number)
