Enable hpet or not in windows 8.1

Should I enable setting hpet or not for perfomance in Windows 8.1 ? TWEAK: Enable HPET (in BIOS and OS) for better performance and FPS - OS Customization, Tips and Tweaks - Neowin Forums and TWEAK: Enable HPET (in BIOS and OS) for better performance and FPS - OS Customization, Tips and Tweaks - Neowin Forums

Is this right or wrong? Last I read, disabling HPET in the BIOS actually improved gaming by reducing lag and micro stutter

Affects hpet benchmarks? What is best enabled or disabled ?

It is not possible to enable HPET in BIOS A14 in the Alienware 17, but it is in Windows.

The higher the QueryPerformanceFrequency is the better is performance. You only get high frequency with HPET. The other timers will give you significantly less frequency. Also note that if your ratio is not 1.0000 you are off set (or you have wrongly OC'ed), enable HPET and you should be without sync problems.

Since your using the R5 it should be disabled by default.

To check enable the CMD promt with admin right and type in bcdedit /deletevalue useplatformclock if you see an error, stating element not being found, then it is already off.

 

Hi
Yes I get this error, then hpet is disabled. Will it be better with to have hpet enabled? Will I notice anything difference to have hpet enabled?

 

HPET, has been abandoned with the release of win 8.0 and 8.1 As for is it better in most cases no.

The results it provides are are so small in scale its not worth using (and the results are both positive and negative completely program dependent). Since the Bios no longer supports it you can enable it through the CMD prompt only, and test it yourself.

Oh yeah, i completely switch to 100% true UEFI, and i love the speed that provides over the old legacy ROM. So if you are looking for a boost, go that route.

 

@papusan - I use HPET with Windows 7 and 8. It sometimes helps a little bit, but more often that not it has no effect that I can measure except using the WinTimer test tool. I haven't found an example (yet) where it had a negative impact. My vote is do it and if you don't like it for some reason, simply disable it. I cannot identify any downside to having it enabled. Unparking the cores is another thing the talking heads say is not necessary (some even say "bad" to do) in Windows 8. I do it anyway, and there is no downside that I can identify. I also disable Intel Link Power Management. The way I see it, anything you can do to minimize efficiency (increase power consumption) and eliminate power-saving latency is the right thing to do.

@mikecacho - what speed improvement are you seeing? I did the same myself, to see if I could put up with life without Windows 7 (for 980M SLI). I cannot identify any speed improvements in anything except for slightly faster boot to desktop (about 1.5 seconds difference, which means nothing to me). Other than this, on my M18xR2 everything seems pretty much identical to Windows 8.1.1 performance using Legacy BIOS or UEFI with Legacy Option ROM (neither of which performed better than the other).

 

@Fox, I noticed a huge boost in boot time, went from up to 8-10 seconds down to a max of 6 seconds, most cases i am booted to the desktop in 3-5 seconds (really who cares tho?). As for real world performance, its so small i would never notice it regardless and measuring it varies on the application.

What sort of tests have you tried already because i have really not had a chance to testing things in depth yet. True UEFI just feels right for some reason.


As for runnung the HPET and WinTimer, the times change each time i hit reset... No real benefit to even using, i do not believe it translates to overall better game performance, which that is what i care about.

 

What about this ? http://www.howtogeek.com/wp-content/uploads/2013/10/msconfig-number-of-processors.png

Mr Fox you say you use Unparking the cores: There is some small ready-made software to do this. What software do you use, or do you Modify the registry? Take a look in this software:

I use always windows power options (Windows Power Plans) at maximum perfomance on everything.

What is the best thing you can use to fix unparking core ?

There is also a box of hpet in hwinfo64 settings that you can cross out. This HPET feature in hwinfo this works ?, when there is no support for hpet in the bios? ?

 

I tested 3DMark Fire Strike, Sky Diver, 3DMark11, Vantage, Valley and Heaven. There is no difference in results using Legacy BIOS, UEFI with Legacy Option ROM or pure UEFI. My games all seem to play exactly the same, too. Boot time is noticeably faster, but like you, I find that to be completely unimportant (unless it is crazy long like longer than a minute or so... something terrible like that, and then I do care).

No, I don't change the configuration for booting the number of cores. I let Windows do that on its own. I use this tool for unparking CPU cores. Coder Bag: Disable CPU Core Parking Utility

You can do it in the registry, but this handy little tool does it for you with a couple of mouse clicks.



I have used this one also, but it gives finite controls where none is really needed. I just want them all unparked, all the time. I don't care about manipulating the behavior of individual cores so long as they all get used up to 100% as load calls for it. https://bitsum.com/parkcontrol/

The bitsum web site has this admonition:

 

Great thanks +1
I use the UEFI with Legacy Option ROM and secure boot disabled (garbage ), it is no point in changing it? I have no extra boost of changing it. I've cut out fast boot and hibernation which I also do not like.

 

Have you tested or use the new beta CPU Core Parking Manager V2?

 

No, I looked at it and thought the purpose of the extra features was pointless.

 

thanks
I thought the same thing. Downloaded the original.:thumbsup:
