HPET in BIOS

[skipper847]

Hi. I have a z77x-ud3h and I7 3770k and in my bios High Precision Event Timer was enabled and decided to disable it as I nearly had enough of this PC any way with micro stuttering etc. When I disabled it and saved bios I noticed straight away that my PC sped up loads as the round balls on windows logo was a lot wider apart then normal when spinning around. I have had stuttering issues for about 3 month but they got worse in last week. I have been Far Cry 3 as thought I would finish it this time be for I Play far cry 4. But the thing is like I said my graphics started stuttering. I formatted my PC and that didn't help and I was trying everything but nothing worked. Until I came across High Precision Event Timer and disabled it and the stutter gone. I did do some research and some say it don't matter if its on or off but wanted a couple of more answers from you guys first if its ok.

Not sure if its the 670 GTX drivers too as some people say they been having problems with the 340+ drivers especially 344.88.

I think it affects input latency so the micro stutter is not really to do with the GPU or drivers. There are differing opinions on this and you can disable/enable in bios and in win7 (not sure about win 8).
Ive enabled it in bios and win7 which increased some sort of timer frequency or something I dont understand properly, from something like 4mhz to 14mhz, however this always created horrid input stutter and seemed to offer no advantage in any real world scenarios.
On in bios and off in win is said to offer better benchmark/over all performance (presumably because there is no inputting anything during most benchmarks) However, I saw no difference myself and still stuttered.
Off in both seemed to decrease the stutter issues (YMMV) and has little to no negative effects in my experience, so I always opt for this setting.

I am also lead to believe that HPET has kind of been dropped for win10.
