Help. I do not know how I set HPET

[fedefrasis]

So, here on a thread I read that entering the command
bcdedit /set useplatformclock true
into the CMD helped with Aero lag, which I had a little bit off sometimes
(GTX 970, FX 8350, 16gb ram 1866mhz, gigabye 970-a-dsp3)
In the bios, HPET Support is ON and I left it be.
Buuut, I got scared that I did not know what the default was just in case, so BEFORE REBOOTING, I typed in bcdedit /set useplatformclock false
and Rebooted.

I read that putting in bcdedit /deletevalue useplatformclock wil tell you if it was on by way of an error if it is off.
I did after rebooting, and no error.
And also, I read http://steamcommunity.com/app/292120/discussions/0/620702121685121684/?insideModal=1 that there's the bios and the windows setting for HPET.
So, I assume Windows was off and Bios On, so according to that post, I put in
bcdedit /set useplatformclock false
(despite the fact that another check on the error one gave no error) and left it on false

Was this how it was set up? How do I see HPET in the device manager?
What do I do about this?
I feel very silly about touching this.
Thanks on beforehand!

I see it on the device manager. Do I type in true or false?

The HPET (High Precision Event Timer) setting is not going to break your computer whether it's on or not. It's simply an upgrade to the old PIT and RTC that used to be used for timing. Essentially, if the HPET is on when you install Windows, it will use it, otherwise it will fall back to the older method for timing.

What you will notice : some software may run better with HPET turned off and some software may run better with HPET turned on. I personally would leave it on, as newer software should work better with than without. In general day to day tasks you won't be able to tell a difference. Only when there is a high speed timer in use, such as in games or multimedia applications such as Blu-ray playback. Benchmark your games either way, so you know if it's a real improvement or just your imagination.

Edit: If you want to check the setting, just type bcdedit into the command prompt by itself and it will list out all of the settings, including useplatformclock.

this is what came out
(I'm in spanish language)
setplatformclock says no
bios says yes
Is this the default?
Also, I feel the system a tad laggier in windows, like when selecting things in the desktop at random, is this possible or me just ocding?
thanks!

Laggier is a hard thing to quantify. Frankly, whether useplatformclock is set to true or not, it won't make any difference if HPET is off in your BIOS, and visa versa. It takes both settings to use the timer. A, it must be turned on, which is done in your BIOS, then B, you must instruct Windows to use that timer with the useplatformclock flag.

Since it's easy to test, you should try it both ways.

You can use WinTimerTester to verify if you're using the older timing method or the HPET timer. If you're at 14.31818 MHz in WinTimerTester you're using the HPET.
