mouse lag + choppy audio + choppy graphics

I have followed your steps re: what drivers to uninstall.

I restarted the pc and checked the driver list again, they reappeared like this:

dm removing realtek, then a restart — Postimages

I juts run latencymon again for 5 mins looks like this now, better right?

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

Highest measured interrupt to process latency (µs): 406.80
Average measured interrupt to process latency (µs): 6.012295

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.

NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.

should I still install that new realtek driver as you mentioned?

Red Rooster · 4 Dec 2022 at 14:50

Murphy said:
Out of interest are you installing the AMD SATA driver? From looking at the images of the drivers you posted you seem to have it installed, if this is Windows 10/11 that shouldn't be installed, it should be the standard SATA controller (MS standard driver).

Thanks for this. Reading now.

So if I understand correctly, I should really be uninstalling the 2 x AMD SATA Controller drivers, and keep just the one Standard SATA AHCI Controller one?

GaryTheSnail said:
Do you STILL get lag in audio, mouse and video?

Well, at the moment it hasn’t happened. It is intermittent and normally only when I start the machine for the day.

There isn’t anything I know I can do to trigger the lag apart from the above so I just have to wait now I suppose

Red Rooster · 4 Dec 2022 at 18:51

...just checked computer again, I thought I would wake it from sleep this time to see if I could trigger the error, and I did, so it is still happening. I just run a latency mon and within seconds got crazy high numbers

_________________________________________________________________________________________________________
CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.

I think Ill go down the fresh install of Win10 in this case. Crazy

Red Rooster · 5 Dec 2022 at 08:41

I just completely reinstalled windows, the problem is till there.

I am able to trigger mouse stutter / audio & visual lag by putting the computer to sleep, then waking it up.

Does this point to a hardware problem ie - start by removing graphics cards, repeating and seeing if it can be isolated to them?

Not sure what else to do

Red Rooster · 5 Dec 2022 at 09:39

I have tried with one graphics card, then another, and then on a different GPU slot on the motherboard....same thing so dont think its the cards.

I wished I have a look at all your devices in device manager for more details so here is no way to export from device manager to a file. I looked at apps on internet but they all really awful.

Now I figured out after googled and downloaded and installed driveridentifier then ran app and it scanned my device manager and uploaded my scan result contained all my device drivers versions and dates.

Gigabyte Z370 AORUS Gaming 7 Drivers

Get drivers and downloads for your Gigabyte Z370 AORUS Gaming 7. Download and install the latest drivers, firmware and software.

www.driveridentifier.com

Now you can download it from https://www.driveridentifier.com/ and install it, run it and upload your scan result so I can see what drivers versions and dates in your device manager much better and easier.

Hey,

No worries at all - truly appreciate yours and everyone elses help and patience on this so far!

I do have an update - I was checking my BIOS version against the latest one - there was an update so I updated it via USB.

I dont want to speak too soon, but eveything is a LOT more stable.... can put to sleep, wake it and it works as normal. Even the latency mon report is consistently reporting no errors and green lights.

I ran the driver app you recommended - here is a screengrab of the page with my list. I see a few are stating 'update' but at the moment this is the best the pc has been so dont wanna now install stuff and cause another issue perhaps!

Red Rooster · 5 Dec 2022 at 12:40

well...I spoke too soon still the same.

Ill install those updates you mentioned.

Red Rooster · 5 Dec 2022 at 12:56

updated the samsung firmware via the app. Still the same im afraid.

I have found another way to trigger to issue. In device manager when I press the 'Scan for hardware changes' button it causes the stuttering.

Red Rooster · 5 Dec 2022 at 17:09

Thanks for all of these pointers.

- I manage to figure out how to disable FTPM in bios... still the same!
- AMD GPIO Controller 2.2.0.130 - I clicked update driver - it says this is latest one which is odd. I tried googling for 3.0 version, couldnt find it though

I dont know what direction to go with this now apart from just changing the MB and processor haha

when i boot pc and it is working fine, I run latency Mon = all appears good.

I think open device manager and click 'scan for hardware changes' = I watch latency Mon immediately go red:
Highest ISR = dxgkrnl.sys
Highest DPC = storport.sys

So what mine goes red doing the same thing.

Is video still choppy? Audio laggy? e.t.c

yep - doing that triggers the symptoms I have previously described

Now I got an idea maybe USB, audio, graphics, network, AMD PSP, AMD chipset, SATA controller and NVMe controller could have IRQ problems that caused high DPC latency.

Please open Device Manager, click on View on menu, click on Resources by type, expand Interrupt request (IRQ) and take screenshots of all IRQ ISA and PCI devices on list.

All PCI devices should have negative numbers.

Here are the screengrabs:

note - there were 511 titled 'Microsoft ACPI Compliant System' so I skipped that whole chunk and sent you only before / after that. It would have been a lot of screengrabs otherwise. youll see what I mean when you look at them.

Thanks for this

I followed all the steps, but cannot see the 'MessageSignaledInterruptProperties folder' for some of them:

Here is a list of all the filepaths I got from device manager, and what ones I could change:

Here is a screengrab of the list after I did those changes...only the 4 GPUs that are not negative out of that list now:

...screengrab of example one where it does not have the interrupt folder:

I made the updates anyhow, still the same issue

Thanks for your help!
