Hi guys, I've noticed an issue with Query Performance method of timers on Windows XP and Vista. So far Win 7 doesn't seem to be an issue. Basically the Query Performance Counter loops in a 2-4 second interval, it can also count up and count backwards really quickly then loop again and again. If you check on Google you won't find anything about it so I'm thinking this is a DBP specific issue, an issue reading the DLL maybe. I know you can have problems with the counter jumping with multi-core processors but this ones odd to me.

Anyway, because this problem exists, how could you check for it so I could switch to a different timer method. A 2-4 second test to see if it loops is a bit much, unless it's done in the background. So any ideas on how to detect this problem?

Does this issue effect IanM's HITIMER() function?

No it doesn't, and I'd guess that the problem Sasuke is having is because he's reading the results into an integer or dword variable - he should be reading it into a double integer instead.

Yes it does. If you can remember, I posted a thread called 'Query Performance Counter Returning Odd Value', I even posted code using double integers. You said I should use HITIMER() and funnily enough that looped as well. When I upgraded to Win 7 the issue went away, but when I tested something on my brothers PC using XP sp3 it looped and that was using HITIMER(). Ever it's a really rare bug, it would totally mess up a game.
