Massive latency-lag issues with my 4090

leonman44 · Jan 16, 2023

I don’t know if it will get fixed but as it is it’s either win 10 with Ecores Disabled , therefore not a 12900k anymore.

Or it’s win11 as it is , I may try them again but also do the optional updates. The reality is that I don’t expect it to be fixed at all.

This has been an issue since the 3000 series. Won't get fixed.

This is not a gpu issue , I used only the motherboard , cpu stock and ram at 4800mhz the issue is still there. With intels hd graphics…

Fixes : windows 10 , custom windows 11 isos.

It’s clearly that is windows doing something at the background that it masks in general windows tasks.

You can also see that MrTOOSHORT with his 13900ks with his z690 dark is not being affected by the issue I have and could easily fix it.

I would go as far as to blame my Asus Z690 Hero (villain at this point) something does not go well with the win11.

My bad I mean around the time they were released I started to encounter this issue. I don't mean it is due to the gpu.

I believe it is something to do with windows scheduler and IRQ's. Well above my knowledge

Hey Guys , thank you for everyone's help i completely fixed everything ! It took me days but finally got a happy ending !

Look at the results , they are constant , spikes are rare and under control , my latency goes lower than i ever seen:

So i am going to tell you what to do so most of you can make at least better !

Here we go :
*always run cmd as administrator

1) You have to unlock the ultra performance power plan , to do so you have to use this command for cmd : powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61

Then go to power plans select the ultra performance plan and change this value from 40% to 100% :

2) The nvidia driver is using the first core (0) from your cpu but everything in windows does as well , so we must set it to an unpopular core to unload the first core use the: interrupt affinity policy tool.
Download it and run it as administrator otherwise it wont be able to change the values. You search for your gpu (mine is the rtx4090) , then you press set mask and you set the cores 8,9 that the system dont really use. Just like that:

3) Now we can use the MSI UTIL V3 to make things even better:
Download it open it as administrator find you card check it and set the interrupt priority as high:

4) This was a mobo driver issue with the Z690 Hero that windows were installing themselves from the very first boot so this is for everyone that has the same mobo or issue as me , ndis.sys was increasing latency also by a lot , what i did is download the latest lan drivers from Asus then opened the device manager found the intels network driver interface completely uninstalled it and directly installed the Asus ones. This completely solved it.

Now you can enjoy Windows 11 with very low latency. 🥳🎉

Interesting. I've tried the MSI util thing but haven't yet tried setting the gpu drivers to another core. Will try when home

so you pressed all the buttons and somehow it got fixed

did not work for me, unfortunately. I'm on z790 apex btw, it's not just your board

For me it was the first step that it did almost all the job the other ones were just a bit optimisation.

You want to increase the processor idle demote threshold. This setting was hidden forgot to tell I used the power plan settings explorer utility to make it visible to the power plans tab and change it from 40% to 100%.

Tried that. "Save" and "apply" are greyed out at the bottom left though.. Tried it as admin too.

Do not change the values from inside the program, all you do is uncheck the box inside the program , this will make the setting visible. Then go to the power plans settings through the control panel and change it from there. I will also try it for my ASU’s laptop in a few hours that has the same issue.

i did that hasn't helped. must be something else you've done to fix the issue.

let us know how it goes with the laptop

The laptop got definitely better but it spikes from times times at 700-800 still won’t exceed 1000 and I won’t get a high latency message , while previously it would go at 1500.

After I did all 3 steps I noticed again that ndis.sys was causing latency as well so I did the step 4 to improve it as well. Now it’s mostly windows kernel that shows up and after that nvidia so I don’t think it can get any better than that , it could be the weaker cpu and gpu.

In my main pc I still have big spikes after booting in my system , windows does a lot things in the background, I need at least 5 minutes for it to get low.

leonman44 · Jan 17, 2023

I tried a 20minutes run and it would fail inside that time. Then i read a few things about tpm causing issues with ryzen cpus so i just kept ptt on but disbled these things from my bios:

After 10 minutes of boot.

It completely stabilized it.

Hey,

I'm having an issue where 4090 in my system can't sit at 117 fps frame cap, even in games it's way underutilized for. It bounces down to around 108 fps when you turn the camera and stutters a bit. I have a 3070ti as my shops working GPU for repairs and it works perfectly. Sits at 117 perfect doesn't even dip to 116 once. Even lowering the settings drastically to make it less gpu bound still perfect 117 cap. Ive done everything I can think of from fresh installs to all combinations of frame caps and vsyncs to high power plans E core disables etc. I sent my 4090 back to Asus to test [Asus currently have it] but in the mean time tried a friend's 4080 and it does the same thing! But the 3070ti is still perfectly fine.

Is this the type of behaviour I would see with this latency issue?

No latency spikes produces stutter at the very moment they happen even if you hit 300 fps you will still be able to notice it.

My in game fps caps usually don’t work at all at high fps so I gave up using them , external fps caps usually cause issues , I used only once the Asus tweak iii fps cap and I instantly regret it.

disabling security device support under TPM also worked for me. and it explains why we had no issues on w10. cheers man @leonman44

edit. welp spoke too soon

Never seen games playing as smoothly as now. Enjoy !

I am curious if windows will let me disable ptt now that i installed windows 11.

Did you let it run for at least 10 minutes after boot?

Also show me the cpu tab so we can see what causes you latency spikes.

Gandyman · Jan 18, 2023

Er this is just idle on my desktop... ? Is this an Asus motherboard issue? I have VBS core isolation and memory integrity off.
