Windows 10: Can disabling HPET High Precision Event Timer cause issues with my machine?

I've heard that disabling HPET can get rid of some micro stutter while gaming. I know that the programs I use do not rely on HPET to function so disabling wouldn't cause an issue there. I can only access the option via Windows, and not my BIOS option not there. Could this cause any interference with some video game anti-cheat, or any other issues that I'm not aware of?


Thanks in advance

HOW do I turn off High Precision Event Timer ??

It's exactly as it sounds. A high precision event timer. It's supposed to be more reliable than programmable timers and the real time clock. It's basically dedicated hardware for hardware interrupt timers with a high level of precision and accuracy.

I also just looked through the manual for the Sabertooth 55i and there is no mension of the HPET. Maybe the board forces it to be on, in which case you're out of luck.

Why do you need to disable HPET anyways? It's best to keep it on.

That disables the driver not the hardware that runs the HPET. You can only fully disable it through the BIOS. If you've looked everywhere it's possible that you might not be able to disable it.

 

Enabling HPET with Windows 10

Hi Aswin,

Apologies I should have provided more detail.

I am referring to the High Precision Event Timer. There is conflicting information out there and I wanted to clarify something with respect to Windows 10 and how it handles this.



I am running Microsoft Windows 10 Professional Build 10586 on an SanDisk SSD with a ~5 year old GIGABYTE P55A-UD4P motherboard; GIGABYTE GeForce GTX 460 GPU; 8GB Dual-channel DDR3.

MonarchX states:

When HPET (High Precision Event Timer) was enabled in BIOS, Windows 8.1 would automatically use it and install system device driver for it. Now I advice to disable HPET because even if you have it enabled in BIOS, Windows
10 won't use it by default, but it will install the system device driver for it. That is GOOD news because Windows 10 finally switched to some other (new?) method of handling latencies and it works much better than HPET!

So the questions are as follows:

Does Windows 10 have its own implementation of the High Precision Event Timer superseding the built in HPET enabled in the BIOS of certain motherboards?

If that is the case then I will disable HPET.

If that is not true and Windows 10 can still use HPET, then I want to know if it has to be enabled both in the Bios and by modifying the Boot Configuration Data (BCD) store. Because
in this post and others I have seen:

MWO: Forums - Massive Fps Improvement Through Enabling Hpet In Bios And Win10

They state:

To enable it in Windows 10, with administrative priviledges you must modify BCD

bcdedit /set useplatformclock true

Thank you for taking the time to answer this question.
