Surprising Observation! HPET On vs. Off

[Kyouki]

While this subject has been beaten to near death in these forums and elsewhere, it's safe to say that 99% of the time it is simply "best" to leave all these settings at default and let the OS decide what timer to use when; there's just too many cases where forcing one particular timer configuration will potentially result in minor benefits for a single scenario, but none or worse at the same time for any remaining scenarios, and visa-versa.

This 200%, timer / hpet works fine/best stock.

I'm reading this and just horrified by all of you.
never put values ​​just like that.
one dude writes to turn on the hpet, for some reason you need to turn on the RTC tick (usetick yes), why?

I think you mixed something up. This is a Post for turning OFF Hpet, not turning it On. I only showed someone in here, how to revert back to stock HPET Settings, if this Tweak didnt help for him.

really?

If you know, using 'bcdedit /set useplatformtick yes' you simply force the system to use a different timer then High Precision Event timer. Its not HPET, as you claim it to be.
As for the website you posted, I can't really seek any usefull Information out of that.

By applying 'bcdedit /set useplatformtick yes', the system will use the Platform Timer rather then the High Precision Event timer. I must say, this is better for older Systems and older applications. In the worst case scenario, it won't do any difference.
Without any Timer, the system would actually perform really bad. By using the command, you simply switch to another timer.

If you know, using 'bcdedit /set useplatformtick yes' is a different timer then High Precision Event timer. Its not HPET, as you claim to be. It has a different clock rate, which is better.

I agree about deletevalue useplatformclock
but, im not understand why you /SET
tscsyncpolicy, disabledynamictick, useplatformtick (RTC TICK).
this has nothing to do with HPET.
Why are you doing bad things to people by giving these commands?

'bcdedit /set tscsyncpolicy enhanced' will spread the timestamps generated by the timer more evenly across all CPU cores. The default value will rather choose one core/thread.

dynamictick is actually a stupid old power saving feature from 2012, which as it says, it dynamically adjusts the Timer Clock Frequency, instead of having it consistent and smooth.
Using the Command 'bcdedit /set disabledynamictick yes' could potentially increase Temperatures by a couple degrees. Its not a good setting to use, if you care about power consumption and you are using a laptop, as I told the guy.
I allready explained the use of useplatformtick.

Can you please tell me, why it's bad?

where you find info about tscsyncpolicy?
useplatformtick yes cause perfomance problem on 1803+, it decrease one-core perfomance so high (1/0.5ms), it is not good setting for all.
anyway, these 3 /set commands not provide disable HPET.

Youre right, these commands are not necessary for disabling HPET, but work in hand with HPET/Timers. They should improve CPU Usage and reduce CPU Processing effectively, and thats also why I saw great performance benefits. Of course it depends on the specifik system too.
I will edit my main post and show how to just disable HPET, without dynamic tick etc.

Thank you.
if you have more info about these bcdedit settings, provide it please.
this is the first time I see an explanation about tscsyncpolicy
anyway, im use RTC tick on z790 because TSC tick gives me 3 different timer res - 0.997 0.999 1000.

maybe you know about that?

I used to believe the same things but I am hard conflicted.

Being that HPET off creates in consistent framerate or gives an improper measurement (or something from what I remember) and therefor metrics *seem* higher but aren't in reality.

I tried changing on and off with HPET/islc or timer 1ms > 0.5ms, but virtually feels the same for most games to me.

Thats Interesting, but I see changes in GPU Utilization and CPU Utilization and noticed heavy stutters in games. Turning it OFF fixed alot of Problems.
I really wonder if this applies to everyone, or if it's Setup Specifik.

These timers, hpets can affect any monitoring programms too, so be careful in your measures
