PC timers inherently run at Mhz speed -- they interrupt every 100th of a second but you can get finer resolution by querying the clock chip. Does Windows let you do this?

Yes: 1.196 MHz precision. The VTD maintains a 64-bit value that is accurate to 0.8 microseconds. This value is obtained by calling the VTD with AX set to 0100h. The 64-bit value is returned in EDX:EAX. The returned value indicates the time Windows has been running based on a 1.196 MHz clock. --------------------------------------------------------------------- | We have the right to defend ourselves | http://www.jim.com/jamesd/ and our property, because of the kind | of animals that we are.
