    Hello guys,

    I've heard great things about disabling HPET, is this possible?

    Macs don't have Bios but EFI and there's no way to access it, AFAIK. I don't think there's any way enable/disable it on a Mac.

    Hello sir,

    bcdedit /deletevalue useplatformclock

    bcdedit /set useplatformclock true

    Using the first of these disables it at least if I should trust wintimertester 1.1.. It says with it enabled my QueryPerformanceFrequency is 14.318 hz and with it disabled I have about 2.3 hz and my DPC latency is lower.. So I would suggest people to try it out, for me it works very well!
