Hello!

 

I have motherboard ASUS M5A97 LE R2.0.

Operating system - Windows 7 x64.

When I turn on parameter HPET in BIOS, the time in Windows begins to lag behind real.
In 1 minute there is a lag for 20 seconds.

And begins a glitches when playing some games.


Is It malfunction of the motherboard?

Easy solution for this one... Turn if back off bud. My understanding is newer motherboards with Windows 7 and higher SHOULD NOT be using HPET. Anyone with a better understanding of this please chime in.

where did you read that?  I would say its complete opposite, older OSes do not support it while new current ones do.. Windows 7 has support for it, but you have to tell it to use it from my understanding.  XP before sp3 did not support it,

It seems articles on it after about 2014/15 are saying to turn it off. Maybe a Windows 10 thing?

This was the Neowin discussion back in 2012 which is saying what you said that HPET needs to set to be the only timer...

 

 

My question to the OP is if you are doing a lot gaming why are you even using Windows 7?

I haven't absolutely understood question.
Why I use Windows 7 and I do not use new OSes?
Because I have more got used to Windows 7

Well you seem to be concerned about performance and Windows 10 is faster. Windows 7 is a dead end with no DirectX 12 support for gaming. I am sure you can get "used" to Windows 10. LOL

      On xiaomi hyperos there's also an option to disable google assistant. I've got everything disabled. Only thing I do have installed is a web wrapped for duck.ai which claims to let you use various AIs anonymously

      I need to understand the rationale of not shipping all of these K2 improvements in a single update/release. It's giving "we will fix Windows 11 but no commitments". It seems to me that they just announce these improvements just to appease the community.

      The term "RTM" is long gone starting with Windows 10. Every current release is a GA build. This is the result of MS making Windows as a Service (WaaS).

      Looks like no official TBW rating, which should be a required listing in my opinion for sites like Amazon (hell, put it on the box too.)
