Windows 10: Is it Worth Disabling "High Precision Event Timer HPET" for Troubleshooting in 2023?

hi, I am currently trying to sort out an issue where my games will have a little stutter when dropping below 60fps, and it's more noticeable at 58fps than 59. I've gone through probably 20 different things, and currently I'm waiting on a DisplayPort 1.4 cable to replace my HDMI 1.4b, in case my FreeSync isn't working properly on my MSI Optix G32C4 doing this will also unlock G-Sync for me to try as wellhowever, I also saw some older threads on reddit 2-3y suggesting to turn off HPET, or "High Precision Event Timer", which I can easily see in my Device Manager. not sure if it would be in my

Is it safe to disable HPET (High Precision Event Timer) ?

Hi Jonathan,

I am Dave, I will help you with this.

HPET is a high precision timer used by the CPU to perform time critical operations with more precision.

It is a myth that disabling HPET will improve game performance, it can actually reduce your performance, you can try it, but it is not really recommended to change that setting at all

 

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.
