I get stuttering in some games aswell as mouse lag. I turned off HPET and every seems very improved along with some more fps and my latency seems to be a lot better.

Interesting! I currently have this enabled in the BIOS. May try some testing and see what I find.

I've always had HPET enabled on both this PC and my last build and never had stuttering or mouse lag issues.

There must be other factors in play, possibly a bug in the BIOS your motherboard uses.

Nice post, I have this option in my BIOS never played with it before... gonna give it a whirl now... never know it might solve the Black Ops stutter.


EDIT: Makes no difference to the stuttering in Black Ops

Well since i turned it off a number of my games dont have as much stutter and mouse lag. Maybe its different for people. I have defo noticed an improvement.

What is it for? I have either 32-bit or 64-bit option.

HPET seems to be a high resolution timer. Wiki says it's not used by XP, only Vista or later so it will make 0 difference if on XP.

It's difficult to see how it could cause a problem, it's just a timer. I would put it down to a bug somewhere in the software stack personally.

Disbabling it may reduce the fluidity of video, since it is used for video syncing / frame timing.
