GeForce Rtx5070 high DPC latency on nvlddmkm.sys - Stuttering
Posted by Opposite_Hand4247@reddit | buildapc | View on Reddit | 78 comments
Hello everyone..
I'm experiencing stuttering and high DPC latency on my system, and after running LatencyMon, I found that the main problem is the NVIDIA driver nvlddmkm.sys (NVIDIA Windows Kernel Mode Driver).
Latency seems way too high, and it aligns with the microstuttering I notice during regular use and gaming.
I've already tried the usual:
Clean DDU uninstall and reinstall of the latest WHQL driver (576.52)
High performance power plan
PCIe power savings, and C-States in BIOS
Still seeing high DPC from the NVIDIA driver.
Any ideas or suggestions on how to reduce the DPC latency from nvlddmkm.sys?
Thanks in advance!

Also having super high DPC latency, 16Kµs on nvlddmkm.sys. Tried all the things everyone else is sharing. 9800X3D 5090 Astral X870E MSI Carbon
DDU reinstalls, Win11 reinstalls, power management tweaks, disabling/enabling C-States, HAGS, all the recommended things. I get in-game frame time dips that coincide with CPU Thread Load spikes that coincide with a drop in GPU usage (which lead to the frame time dips that result in VERY noticeable and frustrating game stutter)
I am at my wits end.
DrunknMunky1969@reddit
So… I may remedied my issue. Played with BIOS a bit, set C-States to ON, curve optimization -10, (started at -20, tested in OCCT, and making +5 incremental changes until thermals were solid). I’ve been playing Division 2 for a few days now without issue. The problem seems to be with the canon of disabling c-states for better stability and performance. The X3D architecture doesn’t need that, enabling C-States appears to give more thermal headroom and provide more energy to the v3 cache.
This is NOT my learnings, I was triggered into more research by this post
lann1991@reddit
Tried, did not work. I too get microstutters, audio popping/stuttering, cursor stuttering. It basically drops everything on the PCIe lane, from the mouse to the audio/network card. Oh, and here is a video of the issue: https://www.youtube.com/watch?v=iMOCiEd1llk
DrunknMunky1969@reddit
Sorry to hear that, I know your frustration.
lann1991@reddit
Its been like that for 3 months now. Pretty sure its pcie related issue, and on the cpu lane. And i did not have that problem before the 9800x3d cpu (i had a R9 7900). So what i'm about to do is change it to a r5 8600g cpu, for testing. And if it won't produce the same issue within \~2 weeks, i will probably rma the 9800x3d. The worst part is that i can not reproduce the problem just like that, its freakin' random, there is no test that will give this stuttering as a result. And it never fully crashes, it never throws a bsod.
TragiccoBronsonne@reddit
How did you figure it was the cpu? Asking cause I'm not sure where to look next, I tried all solutions I could find.
lann1991@reddit
Every time i change something cpu related in the bios (Loadline calibration, CO, PBO, C-state), the issue changes a little bit. Like, without any modification, on default, the stutter can go on more than a minute. But when i change these settings, like lowering the cpu voltage on specific frequencies, the stutter becomes shorter. It could be a bios issue too, I reinstalled the current one for mine, but this time i did a full cmos clear, will se the results (i did it yesterday). The board is a X670-AORUS-ELITE-AX-rev-1. I also wrote to Gigabyte, they were never helpful in the past, but who know, this time maybe they will help with some information.
Heavy_Chest_8888@reddit
Hey did you figure out your solution? I experience micro stuttering too and think my PCIe cable is the likely culprit! It's frustrating.
lann1991@reddit
Yeah, it was the motherboard. I sent it back, they "repaired" it (they did not mention what exactly was the issue). After i got it back from RMA, i sold it, and bought an MSI x870e.
TragiccoBronsonne@reddit
Yeah, mine aren't nearly as crazy and actually seem to be similar to the parent comment in this chain. Although it indicates some gpu-related issue but they seem to have fixed it by changing some CPU-specific settings? s So I don't know what to think anymore... Anyway, that solution as well as many many others I've tried by now didn't help me either.
MuhVision@reddit
Did you ever find a fix?
lann1991@reddit
Yeah, it was the motherboard that caused ALL these issues. I RMA'd it back to the shop, they fixed it, then i sold it, and bought an MSI board.

Bro I had an Asus motherboard when these issues started. It was just a few months after I switched from Win10 to Win11. I RMA'd my mobo as well and now im on an MSI motherboard too. I still have the same issue with the mouse stutters just like you had on your video :(
More-Confidence-7856@reddit
It says the video is private...
lann1991@reddit
Changed it back to public. BTW my issue was the motherboard (don't know specifically what part, they did not explain after they repaired it). But after i found out that, i could search online for this issue with this motherboard, and seems like LOT of people had exactly that problem. So i sold the fixed motherboard, and bought an MSI X870E-TOMAHAWK.
AudemarsAA@reddit
Same issue:
9800X3D, 5080 Founder's Edition, ASUS ROG Strix B850-I...
It must be Nvidia drivers issues. I get audio pops and stutters while gaming here and there.
fuckTheSystem1nTh3@reddit
Hab seit Monaten das gleiche Problem.
Es ist super frustrierend weil ich gern im flugsimulator flieg und mich nie drauf verlassen kann einen flug ohne crash zu absolvieren
ray_fucking_purchase@reddit
Same with my 5080 but ONLY if I use three monitors. If I use two the latency is high but no audio pops or stuttering. With three monitors DPC latency skyrockets, if you move a browser window playing a youtube video the audio stutters and will continue to be unreliable.
So many people now seem to have this issue with zero fix. The 5080 does the same in another system aswell.
AudemarsAA@reddit
Oh I was able to solve my issue.
I swapped to new HDMI and DP cables for my monitors which reduced latency significantly.
Then to eliminate audio pops I swapped the power cable on my steelseries arctis nova pro wireless DAC to a shielded micro USB and also purchased a powered USB hub to isolate the DAC completely.
Something that reduced latency even further was lowering refresh rates on auxiliary monitors that didn't need it.
ray_fucking_purchase@reddit
Oddly enough that's the same exact headset I'm using. Gonna look for a new cable. Sadly the side monitors are both 60 and the main is 120. Even tried disabling VRR in software and the display no dice but I'll look into the shielded cable.
AudemarsAA@reddit
Yep. Also uninstall steelseries GG and use Peace GUI for your EQ instead.
I basically had ChatGPT do a research on every possible reason my latency and audio pops could come from and eventually it worked lol.
Also try isolating each monitor and cable to see if one of the specific monitors could be the issue too.
Downunderdent@reddit
I'm just replying to let you know that uninstallying steelseries gg greatly improved the latency on my nvlddmkm.sys. Thankyou.
TheRealLurtz@reddit
did you ever get it fixed? I am losing my mind over here with the same issue. I've tried everything even niche stuff I found on reddit.
DrunknMunky1969@reddit
Yes, fixed. Tried dozens of things, often at the same time, so I cannot pinpoint what exactly fixed it -- however, this post
(https://www.reddit.com/r/buildapc/comments/1nos8gd/i_found_a_fix_for_my_bad_1_lows_stutters/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button)
Seemed to get me over the last hump.
TheRealLurtz@reddit
Thanks. That didn’t fix it for me but it’s not happening when I roll back to 566.36 from Dec 2024. 😅
TragiccoBronsonne@reddit
Managed to solve this by any chance?
Electrical_Delay443@reddit
how much specifically? im getting like 500-600µs (Highest reported DPC routine execution time) on 6-7 minutes, is that normal?
Expensive_Seat_5467@reddit
Hi everyone,
I've been struggling with persistent DPC latency spikes, especially related to
nvlddmkm.sys, and I'm at my wit's end. I’m using a Gigabyte RTX 5070, AMD Ryzen 5 5600X, and 32GB of DDR4 RAM, all running on Windows 11.I'm also running a triple-monitor setup using high-quality DisplayPort cables, so it’s not a signal degradation issue.
What I’ve tried so far:
NvThrottleMaskto 0x0, removedUsePlatformClock.msmpeng.exeshowed high hard pagefaults in LatencyMon.Despite all these efforts, nvlddmkm.sys still shows DPC routine times up to 2ms, and audio popping or latency spikes continue under load.
It’s honestly frustrating that we’re dealing with these kinds of issues on high-end GPUs in 2025. We pay a premium for this hardware and still can't get stable real-time performance.
Any suggestions or solutions would be greatly appreciated.
Heavy_Chest_8888@reddit
Hi did you find the solution to this please? 🥺

u/uray_fucking_purchase
Did any of you find a fix? Our common thing seems to be three monitors setup
Screenshot of my LatencyMon after just 1 minute - "current meassured interrupt to process latency" seems to balance 60-120us but the moment i turn on Spotify and play music its constantly 130-250us, not to mention these high ass spikes in DPC latency...
My setup is 9800X3D + 5090, i have not yet tested turning off other monitors and checking then. When i had 4090 latency definitely wasnt that high
ray_fucking_purchase@reddit
A super short 1.5m HDMI 4k120hz cable "fixed" the issue barely. I still get audio pops and crackles maybe twice a day instead of every 5 min. So not a true fix.
The one that worked 100% was using a single monitor on my 5080 and the HDMI/DP port on my motherboard. Sucks having to do that but there are zero audio issues with that method.
Seems like Nvidia's drivers do not play well when mixing multiple monitors and different refresh rates VRR or not makes no difference in my testing's.
I've already spent over $200 total on cables to get to this point it's ridiculous. I have a 6600xt that can have 120/144hz on one display and 60hz on the others with zero issues.
ayoomf@reddit
Thanks for the update, i gave up for the time being and just use it as it is but it is damn annoying considering this is top of the shelf tech..
Greecelightning5@reddit
Man, this is super not great to hear. I've got basically the same symptoms as other here and done pretty much all the same things other have tried. I currently have a ticket in with Nvidia and am working with a rep, but they are already being less then helpful. They are saying that they have never heard of this issue but as I check forums, I can see it all over the place. I also posted on their forum to try and see if I can get others to post.

Any luck mate?
vBrad@reddit
Hey there, did you manage to fix this?
ray_fucking_purchase@reddit
I went as far as testing 3 separate monitors, 3 more cables, Tried Windows 10 LTSC instead of 11.
Onboard audio, USB DAC, USB headset, PCIE sound card, all same results high dpc latency. Bazzite does not have this issue, it's strictly Windows 10/11 driver issue that keeps popping up.
Impossible-Car-8094@reddit
I have the same problems..
i swapped my psu from corsair 750w to seasonic 750w atx 3.0 nothing changed..
i swapped my cpu from 7600 to 7800x3D nothing changed..
i swapped my gpu from rtx 4070 to rtx 5070 nothing changed..
I did all the tweaks on the internet and format my computer 100 times nothing changed.
I even bringed An electrician to test the electricity in my house he said i dont have problems.
i cant even watch streamers or youtube video without lagging and sttutering because of the high dpc latency of nvlddmkm.sys and HDAUDbus.sys. I play too much conter strike and Ingame it's even more worse it's like you are playing on console on 60hz monitor with 60fps while i have a good computer..
I'm at the end of my hopes :/ i start thinking of selling my computer, stop gaming forever and buying a cheap computer just for surfing on the internet because this shit is killing me softly everyday without any solution..

I don't understend much, but have you tried to disable VM in BIOS? It solved for me.
OthoAi5657@reddit
Same here i can improve from 1,6 to 1,0-1,1 but nothing i try works on my new windows 10 on my old windows 10 its on 0,6 not the best but better and i dont get it i did everything the same but get worse results i losing my mind
ErxQQ@reddit
I'm constantly experiencing lag in games, and here I'm getting very high readings too, and there's no solution; I'm going to lose my mind.
Diboudo@reddit
try lowering the pcie-gen settings in BIOS - it's probably "auto" by default. the gpu is gen5 and your board is gen 4. Also try setting it one lower to gen3! It's not ideal, but after spending an amount of hours i'm ashamed to say trying to fix the issue, this finally worked for me. Hope this helps.

favabean28@reddit
For anyone else who has tried everything, set Low Latency Mode to “Ultra” globally. I was having spikes in the mid-500s to low-600s just from pulling up a YouTube video. Now I’m in the mid-200s. Still not optimal, but significantly better!
Rizzesockan@reddit
I just got my 5090, and I experience stutters as well. Checked latencymon and indeed high DPC latency with "nvlddmkm.sys". I am on the latest driver 576.80.
CPU: 9800x3d
TragiccoBronsonne@reddit
Let me know if you find a solution, same shit here.
vBrad@reddit
Any luck here?
TragiccoBronsonne@reddit
Nope. Couldn't find any solution since and just moved on.
vBrad@reddit
After trying a million things, I downgraded to driver 560.84 last night and it was fine over 2 hours of gaming. Testing again tonight.
TragiccoBronsonne@reddit
Thanks, I'll try it out later.
Wonderful-Ant-3307@reddit
latency 44-65ms according to nvidia app overlay during gameplay just now with AVOWED..seems high...so what to lower this?
rtx5070+i7 13650hx(mobile cpu--in my desktop)+16gb single ram 5600mhz
so how to lower latency? read that 30ms is decent ?
Genco55@reddit
I have the same issue with Rtx 5060Ti 16Gb, did anyone found any fix for this annoying issue?
I am dealing for like a month with this problem, and yes I can confirm that sound pops and random(mostly after 2 hours gaming) pc freeze leading into an actual crash forcing me to manually shut the pc down..
Genco55@reddit
who is wondering the solution I found was to go into my BIOS and lower my PCIe Gen to 2.0, try tweaking with that for your selfs, 3.0 didn't work for me but 2.0 did.
Dragonfly_Senior@reddit
Update ? Same Issue trying for weeks now.
cunnning_stunts@reddit
Same here (5070 Ti) and I've tried a LOT to fix it because I do most of my gaming via Moonlight and this issue really kills it.
jollycompanion@reddit
I am testing something that keeps the us at around 1k. I am also on a 5070ti and I rolled back to 572.83 via NCleanstall, then I set my performance in control panel to prefer max performance and it seems to have stabilised? I am unsure. More testing needed but before I did this my system would also lock up completely and stop responding until hard reset so who knows.
cunnning_stunts@reddit
After fiddling with BIOS settings and only making things worse, I found some things that actually helped my situation.
First I used GoInterruptPolicy to force the Nvidia driver to use real CPU cores only. I set the GPU entry to IrqPolicySpecifiedProcessors and checked cores 2,4,6,8,10.
Then I used PowerSettingsExplorer to make these available in the power plan settings:
Set to: Demote 0%, Promote 100%, min/max cores 100%
Lastly, I set "prefer max performance" globally in the NVIDIA Control Panel (which I always do anyway), and turned HAGS back on - which definitely had a positive impact.
Now I’m in the green in LatencyMon all the time. I tested for 10 mins while I opened some games etc. No more pops or stuttering, which initially had me blaming and fiddling with my network, Apollo, and Moonlight.
I’m not sure if this matters, but I was trying some old driver versions while debugging and currently have 576.15 installed. I don’t have time atm to test a newer version and potentially have to roll back.
Another thing to note is that I only use my system for gaming and when it’s not being used then it’s asleep, so all I want is max performance. These settings (un-parking all cores etc) will obviously use more power and degrade components faster compared to how they’re designed to run with light loads. I'm also not sure if all of these things are necessary and I don't have time to test further right now.
jollycompanion@reddit
Thanks for getting back to me.
I ran some further tests yesterday as well, with my settings and didn't have further lockups or latency spikes. Highest one ever recorded was 1.3k from a program starting.
I will fo further testing today and try your settings if things go south.

Fearless_Music_8716@reddit
I encountered a similar situation, and I used a software to solve most of the problems. Although it still causes the DPC to suddenly rise, there has been significant improvement.
My configuration is Rog Strix 18 (2023) 13980HX, 4080, 16 x 2 (6600 C40), Win11 23H2 Pro. This is the DPC result after optimizing with this software, which is called BoosterX
Apprehensive_Bug_172@reddit
I have the same thing. It might be my Synology NAS. I’ve disconnected it from the network and for about an hour DPC latency is good.
I’ll try to fix it on the NAS side. Athough I’m not really optimistic I’m knowledgeable enough to do it at least I’ve figured it out after god knows how much time.
Just in case someone somewhere has a similar problem.
Usual-Membership3058@reddit
i am facing the same issue with an 5080, DPC latencys around 9-16k μs.
i went the full route and reinstalled windows - nothing helped. also the issue travels with the card onto other systems.
in 576.2 slightly higher DPC latency issues where fixed https://us.download.nvidia.com/Windows/576.02/576.02-win11-win10-release-notes.pdf but 9k μs is not slightly higher, my old 3090 has a latency of 350μs.
whats your latency?
