Some of you may know the kernel32 function GetTickCount. I''m using this to perform frame rate stuff, but I''ve noticed that it seems to be returning impossible values sometimes. GetTickCount is supoed to return the amount of milliseconds that have passed since windows was booted up... so, what I do in my loop, is calculate how much time (in milliseconds) has passed since the last loop. Nothing complex... but sometimes, I get a time_passed_since_last_loop of 0. Is anyone familiar with this? If not, is there another way to get accurate timing on the windows platform?

GetTickCount() isn''t very accurate - I would say it has a range of +/- 5ms accuracy or worse. The following snippet of code should give you a place to start from:

QueryPerformanceFrequency( &Temp );
iClockFrequency = (int)Temp.LowPart;
