Hi guys, I could not resist joining this forum to add my two cents. HPET made me go nutz, too.

 

 

HPET on/off making a significant difference is definitely NOT snake oil.

 

 

On my previous Win 7 build (DAW only), disabling HPET in BIOS & OS resulted in a DPC latency of comfortable 2 - 4 micro seconds. Before that, the latency rarely ever dropped below 130 micro seconds, which already has been quite good regarding the 270 which I

^ You need to elevate the command prompt. It won't work just because you are using administrator.

thread is 2 years old, still not a single proof or evidence that this works.

 

on the contrary, all the claims that this works makes me wonder what's the purpose of deceiving people into this?

Personally, I think it is just the placebo effect instead of subterfuge in many cases. The wintimertest results are enough to convince folks that it must improve speed objectively everywhere. We aren't immune to such things by any means either. We might defrag an HDD and perceive the same thing to be honest. Tricks of the mind. It's similar to people who listen to uncompressed audio (versus XYZ compressed audio) and claim they can hear a difference, yet double blind studies show otherwise. Expectations are everything, huh?

well, i can listen to 128kbps audio file and find differences from the same uncompressed format; 320kbps, not so well. Buy i agree with you, even a defrag can make a subtle difference so this is more a placebo effect then anything.

Well 128kbps is the questionable line afaik (or 192kbps -- depending on the compression algorithm). It's the higher bit rates where you can't perceive in double blind tests, yet, people claim otherwise.

well, considering that when i was learning Java i made a small audio program that i could insert two filters:a low-pass and a high-pass; learned pretty quickly i was going to become deaf more faster then i expected lol

You don't, If your computer came with Windows, it's already optimized for the hardware.

But it should be in bios!

Why is it not?

Your laptop is probably too new (pretty sure mine doesn't have it either). The only good reason to have the option in the bios was during the early years when the actual hardware implementations weren't well tested or supported.

Do you know any other method that reduces lag and improves gaming?

generally there's only one solution for that. better hardware.

Well you can still force only HPET in Windows (as was outlined here in the first post) using step 2 if your laptop supports it (you just can't turn it off/on in the bios). Note, I am not saying this will improve your performance (I don't believe it will).

For many years already my HD never scream.  After turn this on:

bcdedit /set useplatformclock true

 

I heard my hard drive screaming.  I mean it has never make any noise before.  So yeah I think I will need to get a new hard drive to back up my data soon and then get back to it's original setting... not turning on the HPET that is.

HardBag (or anyone else here),

 

How do I check the BCD on what's the current setting of useplatformclock, before making any changes to the BCD?

 

BTW, I have checked my system to see if Invariant TSC is supported or not. Says it's supported.

So does that mean I don't need to edit my BCD?

 

For those who don't know how to check, here's how:

 

1. Open AIDA64 -> Motherboard -> CPUID
2. Look for the field "Invariant Time Stamp Counter", and check whether it's supported or not.

For the first question: type 'bcdedit' on the command line. 'useplatformclock' will appear under the Windows Boot Loader section if it set.

 

For the second question: the TSC is completely separate from the HPET timer. See: http://en.wikipedia.org/wiki/Time_Stamp_Counter. The invariant version of the TSC is an updated version of the TSC on newer processors:

 
17.13.1 Invariant TSC

The time stamp counter in newer processors may support an enhancement, referred to as invariant TSC.

So... which ones are best?

 

without

with

(2,33843/14,31818)*100 = 16,33189413738338

this means get 16% better cpu performance or fps?
