15ms ... on what kind of hardware ?
getTickCount isnt the best choice, since it's normally using a counter which is running at @ 1Mhz I think ... so no good choice. use something like this to read the number of cpu cycles instead. then you need of course to clean the result from effects of your multitasking environment
Code:
_int64 CTime::getTime(){
_int64 rdtsc_time;
__asm
{
rdtsc
mov dword ptr [rdtsc_time],eax
mov dword ptr [rdtsc_time+4],edx
}
return rdtsc_time;
}
( btw, thx for william for this
