I don't know.
I would think that they are not using HPET by default, as it was only the
Ryzen Master software which enabled it on my system.
I don't
think there should be any issues with changing that setting on a non-Ryzen system to see if it helps.
Deleting the value using the code I posted should be fine.
If that does not work, you could try forcibly disabling HPET with this command:
Code:
BCDEdit /set useplatformclock false
However you do so at your own risk.
I don't think this should make any difference for Intel systems unless you have forcibly enabled HPET yourself, and even then I don't recall ever having issues like that with my i5-2500K.
EDIT: Just tried manually enabling it on my 2500K system and it killed performance there too. Seems like having HPET enabled on any system might be the cause of this.
