Windows 11 22H2 high interrupt to process latency on new 13th Gen Intel build

so, is the same issue as another reported yesterday?

Nice find.
Glad I already have it disabled on my realtek.
Looking good on my AM5?

Tbh, my work Win11 install has this habit where it times out loading a web page. I can use wget/curl from wsl and the page is pulled just fine. Try it in a browser, timed out. Switched browsers too, with no effect. Opened up a ticket to IT support, they couldn't figure it out either. It just looks like there's a lot of warts surrounding Win11's performance still :(

Keep in mind my problem can also be stemming from customizations our IT does to Windows when setting it up, but I'm sure about that and the problem is similar to what OP describes (i.e. seemingly random performance issues).

Yeah, there's absolutely nothing I can trace this to. Event viewer being clear is a shock, the only lead I have is the very high interrupt to process latency in latencymon - but since it doesn't seem to be caused by a driver, it also doesn't seem to be able to tell me why it is happening.

Some things to try:

- https://www.sordum.org/9480/defender-control-v2-1/
- https://wpd.app/download/ - disable everything including advanced and block TM.
- https://www.grc.com/inspectre.htm
- Disable TPM in BIOS, disable/uninstall TPM driver in device manager and make sure it stays disabled after restarting.

Windows Defender was disabled, I double checked it. Will also check WPD - nice that something's coming out of the thread. Best of my knowledge inSpectre doesn't need to be used on Raptor Lake as the CPU should contain pretty much all fixes for performance degradation arising from Spectre and Meltdown. I mean, this is a i9-13900KS, if this CPU doesn't what does?

No, doesn't seem to be the same problem. The hard pagefaults aren't an issue, unless their number is excessive (a hard page fault merely means that data accessed isn't currently stored in RAM and was fetched from disk), and there was no Ethernet cable physically connected to the PC (I always install offline and then login so I don't have the risk of driver overwrites, since Microsoft doesn't seem to respect the registry key that tells Windows not to update device drivers at all anymore).

Nice find.

This number seems very similar to what I get under Windows 10:

Hi,
If using wifi try wired
The board has two 2.5 nic's try both.
I haven't had many issues with 11 or 10 for that matter so think the issue is a msi issue on 11
But yeah third party AV would be the easiest way to get defender out of the way a bit plus run W1z's scripts
 
Just thinking out loud here since you appear to have tried most everything. Maybe try disabling both wired/wireless networking devices to verify it's not a driver incompatibility in 11 versus 10. Same with any onboard audio that you might have enabled.

If I remember correctly, you bought the board used. Did the previous owner disclose why they were selling?

Yeah probably, just shooting in the dark there.
As for the ethernet, I would at least try disabling unused ethernet/wifi devices in device manager to see if that helps.

Yeah that's really mind boggling they don't respect their own values and this bug has been there since Windows 10... Still unfixed. This is the reason I keep windows updates disabled and blocked in firewall. It insists on downgrading my Radeon drivers otherwise. :laugh:

My latencymon results were from latest Windows 11 build by the way.
 
Here's another idea: when Win11 detects hardware capabilities, it enables all sorts of protections and security features that make use of Hyper-V (yes, it turns it on even if you have it disabled in the features panel). You could try getting rid of that and see what happens. I think it's easiest to just disable virtualization support in the BIOS, if it's not there Windows won't try to use it.

They are identical Intel i225-V B3 stepping 2.5GbE NICs. Neither were plugged in, and drivers for the Intel AX211 WiFi 6E adapter were not installed. I haven't disabled them, but since they were unplugged, it's reasonable to assume they weren't doing anything. Tried running W1zzard's Visual C++ installer batch (massive timesaver), but it was too slow to complete.

I went in the settings to fudge and found that it enabled core isolation by default, and disabled it, which is why I listed that on the OP. There was no effect. Disabled virtualization support entirely in firmware and that also did not have any effect. Which is why I'm beyond puzzled... I just have no idea! Nothing I ever tried works, it's the single most bizarre thing I have ever run into.

The SSD that it's installed on is benching full speed under Windows 10, and I managed to get CrystalDiskMark on 11 as well, it's showing the usual 2500 MB/s read and 1800 MB/s write the WD SN350 should be capable of. At this point, I'm about as lost as a blind man in the middle of a firefight

If you're using Pro, use Group policy to block the driver updates.

I'm on Pro for Workstations, which is the fancy version of Pro that supports ReFS and high-RAM PCs, otherwise it's identical.

Need to double-check that setting on gpedit, but the ExcludeWUDriversInQualityUpdate variable in HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate registry key doesn't seem to be respected any longer, that much I can tell you. So if you just do it from a tool such as Winaero Tweaker, it's not going to work.

I can confirm that the gpedit method is working for me on two different installs.

Missed this, he didn't explicitly say, but I think he might have an addition to the family on the way soon.

Either way it looks like he barely touched the motherboard at all. The plastics were all still installed, even the adhesive written "remove" on the preinstalled M.2 thermal pads were untouched. All of the accessories were sealed, including the wifi antenna, and all bundled cables, I'm quite willing to rule out hardware damage entirely, especially when everything is fully functional under pretty much everything except Windows 11. If there were any hardware damage so to speak, I think Windows 10 and other bootable OSes would also be misbehaving quite badly. don't you agree?

Completely agree that it's probably not a hardware defect. My only thought was if the previous owner put it together and had similar issues with Windows 11 they may have been trying to get rid of it.

If you've disabled the onboard NICs/sound in the BIOS and you're still experiencing the issue it probably is just down to the specific combination of hardware and Windows 11 gremlins.

These are the worst kind of issues to have to diagnose. :(
 
And, if the Windows ISO was corrupted, perhaps ? i think there is checksums available.

Winaero offers a few options of this type while remaining focused on visual and menu changes. There is reason to believe majority of other programs do successfully block this type of behavior.

Didn't catch you were using Workstation. At any point did you try the standard version of Pro?
Fairly sure you flashed to most current mobo BIOS. Just investigating if this is less of a W11 than a Workstation W11 hardware issue.

Did not try the regular Pro, but they are 100% the same SKU, Pro just has a lock on ReFS usage. Chances are that if something doesn't work on ProWS, it won't work on Pro either.

To change Pro to ProWS you don't even need a reboot, just run slmgr -upk, slmgr -ipk (ProWS key) and slmgr -ato to activate.

And, if the Windows ISO was corrupted, perhaps ? i think there is checksums available.

I've checksummed it, redownloaded, tried different methods of deployment, none were successful in remedying the problem.

It's as much as an enigma to me as it seems to be to everyone here. At this point I am just going to chalk it down to a bug in the Windows image currently hosted in Microsoft's servers. Might try downloading 21H2 later, but for now, I am going to play some games. Fallout 76 is so unbelievably smooth after months of playing it on a 3050M! :eek:
 
Don't install KB updates post 2023-2-14, for sure.

2023-2
Nothing reported

2023-3
Install errors and SSDs bug

more and more 2023-4

Sorry it's in French

I'd really appreciate suggestions and input, because I've just about had it. Finished setting up my Win10 installation and plan on just enjoying my new PC for the time being. It's been months since I had a good PC to play a game on and I'm not about to let this spoil it. :oops:

I use Windows 11 22H2 build 22621.1555 and no problems, but some previous build from 2022 was not good.

Some stuff I would try to have lower DPC latency:

- Clear the CMOS, the button in the rear of the motherboard.

- Believe or not, but sometimes this FIX DPC latency problems.
This is a CMD file to check and fix the File System and Operational System Integrity.
Run it as admin, it is from https://forums.mydigitallife.net/th...fications-overview.83744/page-57#post-1734651

- USB pooling rate above 500Hz can cause problems, the default is 125Hz.
Check https://shorturl.at/kmxy3 and https://shorturl.at/irT79

- Disable Windows Hibernate

- Disable Core Isolation and Memory Integrity
https://www.thewindowsclub.com/core-isolation-and-memory-integrity-in-windows-10

Do the "Processor idle demote/promote threshold" tweak
use the Windows power plan settings explorer utility
and unselect "Processor idle demote/promote threshold"

New options will appear and set the Threshold to 100%.

- Make sure MSI(Message Signaled-Based Interrupts) is enabled for the GPU, use utility V3

Well, there goes my last hunch then...

I know and regularly double-check on most of these, such as the MSI mode. Power management I do manually on my card, to ensure flat clocks and that it doesn't power throttle as I hate the variance. Still, didn't get to the point where it would matter, as a 3090 could probably drive the Windows 11 desktop a million times over at 4K before it realistically ran out of gas.

Hibernation is always disabled on my setups, as is fast startup - this is a desktop, after all. Mouse is set to 250 Hz and keyboard at 125, I'm also well aware of the negative impact (in games) of excessively high polling rates. As mentioned, the whole deal with CMOS, bios reflash, etc. it's all been done. That leaves the processor idle demote thing. Wouldn't you agree that it's wayyy to obscure a setting for a freshly installed operating system? Still, will add to the bucket list.

Just played some games for about 4 hours straight on Win10, and performance is amazing. In Fallout 76, two of my P-cores are practically always pegged at 6 GHz. That's amazing!
 

Hey, I've perused your thread, but it doesn't seem to be the same issue. I would be happy to just ignore LatencyMon if my PC was usable to begin with under Windows 11.

I've disabled all of these things as per the OP, and even tried to reinstall and setup the Management Engine driver first thing as a friend suggested, but to no avaiI.

The only leads I have are LatencyMon being off the charts high and HWiNFO64 reporting extremely low effective clock speeds:

20230423_085049.jpg


P3, the one it reports being at 79 MHz, is one of the 6 GHz capable cores in my sample. So I honestly don't understand, I haven't been able to solve this issue yet.

Performance in games under Windows 10 has been excellent, so at this point I'm just considering writing off using Windows 11 on this system entirely until 23H2/perhaps Windows 12 releases to the stable ring.
 
It seems rolling back to windows 10 makes the most sense, i will be doing the same.

I installed Windows 10 by chance, because I had an USB stick with its installer on it and was banging my head against this problem from the get go, I wondered if I had a corrupt Win11 install media, it turns out that I didn't.

That turned out to be the only solution I've found thus far. It just seems like that under Windows 11, my CPU is permanently stuck in an idle power state under most if not all conditions. Active clocks may even report as going up, but effective ones do not actually go up.
 
Exact same issue my friend, hwinfo reports high frequency limit clocks, but effective clocks are below advertised 3.7ghz LOL. Idk wtf is going on.

Guys, i will be getting a new high end mobo today coupled with win 10, ill report back if the issue persists. Will use same hardware.
