QueryPerformanceFrequency help

[leoalvesmachado]

Hi everyone,

I have a code that uses QueryPerformanceFrequency. However, the machine I need it to run doesn't have high resolution performance counter. Is there a similar method, even with lower precision, to do what it does?

Thanks for your help

The QueryPerformance... functions don't require an HPET.

Well, I don't know what it requires, I thought it was something my processor don't have, as mentioned here:

The thing is, I always get Error when I call QueryPerformanceFrequency, and I would like to replace it. Is there a way?

Why do you want to replace it? Why do think there's something else that'll act as a high resolution timer?
