    I found this perfect combo

    HPET on bios turn on, Hpet on windows Go to CMD and enter this bcdedit /set useplatformclock true and last but not the least download this tool called Set Timer Resolution for windows 8 the default is 1ms putting it to maximum resolution which is .05 ms makes a difference games don't stutter no more. and u can download it here http://www.lucashale.com/timer-resolution/ now those jittering and stuttering when hpet enabled on windows are now gone.

    Personally HPET On performs worse in Non-gaming situations for me.

    And it gives better performance in many games on a per game basis. Some like FFXIV 1.0 have heavy microstuttering with HPET on.

    Just my $0.02

    I also messed around with HPET just not that while ago, and while it offered "certain" smoothness in BF3, it also gave horrible spawn stutter, it went away after a min or two, but this happened consistently for the 1st 3 to 4 spawns each round.

    if your on vista or higher you should use latmon instead that program is know to give wrong readings on vista and higher

    I have my hpet enabled in bios always and thats it I didnt change anything in windows 7 x64 or whatever.. should I leave it like that ? is it the best ?


    edit: you guys said enabling hpet for windows by cmd is the best but why in earth its not enabled by default if bios hpet is enabled from stock ? :D

    if you have no issue leave it be only reason to start messing with it is if you have games that studdering, or latency spikes causing audio popping/crackling even thats only if those problems bother you enough to bother

    actually, I have speaker position popping in my x-fi for years when playing music and scrolling down pages.. BUT if I use ASIO I have no issue at all.. So its has to be HPET ? or just microsoft directsound (or daniel_k who made the drivers :D).. because you know with ASIO there is no interference just sound card and music.

    ok that took long... and I wanna ask about core unparking.. is it worth ? I mean are there any FPS improvements in enabling hpet in windows also core unparking ?

    Your asking questions that have been answered already in this thread pretty much. Have a read instead of people re-typing what has already been written :)

    Well then you would know their is no specific answer then! It seems all systems are quiet different as the 10 pages have proved. You just have to try the various on/off's to see what works best for you. Default works best for me. On in BIOS and off in Windows.

    I have no time for testing.. then Im gonna leave it as it is. And how did you test it ? with latency checker ?

    Here he goes again with trying to say everything he says is fact for all people. Not so. See previous 10 pages for proof of that.
