OMG. Win10 nepouzivaji HPET. Uz jsem to dokazal v jinem vlakne.
Yes, the OS uses TSC on most modern systems, but it WILL enable HPET if a specific program is written to use it, regardless of the HPET BIOS setting. That’s why most X99 boards got rid of the HPET settings option.
As for the „software driver“, eventually the OS WILL install the HPET driver when a piece of software activates the timer. (Again, regardless of your BIOS setting).
Not everyone will see higher latency when HPET in enabled in the BIOS initially. It’s system hardware and software configuration dependant.

Zadny patch na HPET pro Win10 se nechysta a nebude. Patch na BIOSY dostaly jen nektere desky, ktere ho potrebovaly, nejedna se o plosny jev, a zadne renomovane redakce to zatim nepotvrdily.
AMD pouze plosne opravi FMA3 bug a jejich taktovaci utilita uz nepouziva HPET, ovsem vliv na vykon po oprave opet nikdo renomovany nepotvrdil.

We have reduced DRAM latency by approximately 6ns. This can result in higher performance for latency-sensitive applications.
We resolved a condition where an unusual FMA3 code sequence could cause a system hang.
We resolved the “overclock sleep bug” where an incorrect CPU frequency could be reported after resuming from S3 sleep.
AMD Ryzen™ Master no longer requires the High-Precision Event Timer (HPET).
Zase placate nesmysly a nepodlozene blaboly, jako obvykle.
