Best leave HPET as it is..don't mess with it. Reason being, that all the current hardware and drivers are; configured and tested with default stock windows settings by the manufacturer. Some sources I currently checked on the net http://stackoverflow.com/questions/...ndows-system-time-with-millisecond-resolution http://msdn.microsoft.com/en-us/magazine/cc163996.aspx#S8 It mentions that.. Windows 7 has a default 15ms timer resolution (minimum)... But on my system its 0.917ms maximum value (close to 1ms) anyways.. Translates to 0.891-0.905ms kernel latency timer (via latencymon) changing the timer resolution to 0.466ms (close to 0.5ms) via the tool Translates to 0.406-0.421ms kernel latency timer (via latencymon) Funny thing is, I haven't even enabled HPET in Bios or in Windows 7 via the CMD command (lol) to change timer resolution.
