Persistent DPC Latency & Stutter on Brand-New 2025 ROG Strix – BIOS Updates Didn't Fix It

[NotPerFect]

 I've been dealing with this issue for months now, across multiple BIOS and firmware updates, and it's getting frustrating.

On my brand-new 2025 ROG Strix (BIOS fully up to date, clean Windows install, all drivers current), I still get random micro-stutters both in games and even just browsing the desktop. It's subtle but very noticeable once you know what to look for – mouse cursor hangs for a split second, audio clicks, games hitch for a frame or two.

LatencyMon confirms the problem in minutes:

Highest interrupt to process latency: 3608 µs

Highest DPC routine execution: 1185 µs (ntoskrnl.exe)

Highest ISR routine execution: 230 µs (wdf01000.sys)

This is not normal for a high-end gaming laptop. I've kept BIOS and firmware updated (Asus has released multiple updates since I bought this machine) and nothing changed – the problem persists exactly the same.

Please stop treating this as a Windows quirk and acknowledge it's a firmware issue. There are reports going back to 2021, and it's still affecting brand-new 2025 models. It's unacceptable for a premium laptop to have this kind of stutter baked into the system for years.

@NotPerFect 
Could you please provide the full model of your laptop, as well as the BIOS version, system version, and graphics driver version you are using?
[Windows 11/10] How to check the model name and BIOS version
Does the lag occur when you are just browsing the desktop or playing music, or only during gaming?
Is there any difference between using the laptop while plugged in and on battery mode?
Please try temporarily disabling Wi-Fi and Bluetooth, then test to see if the issue improves.
Please also provide a video showing the issue for our reference
We apologize for any inconvenience this may have caused.

I have the same problem in my laptop rog strix G16 G615LR 2025 not even 2021-2024 also 2025 laptops have this problem there is no fix for this microstutter in games like the witcher 3 cyberpunk widnows become slow and mouse sometimes freeze after too much research its firmware problem i tried to install windows on another hard disk and everthing solution you can imagine latencymon show high dpc also i hope asus fix this the Unacceptable

 I found out it only gets that bad in LatencyMon (sometimes even worse than the screenshot I posted – up to 15,000 µs) when switching to Silent Mode. That’s when LatencyMon goes completely nuts.

When I switch to Performance Mode (Balanced in G-Helper), things go back to “normal” – around 250–600 µs – but still far from perfect, and the red warning at the top still appears.

Since we’ve got the same model, that’s interesting to compare.

In a perfect world, LatencyMon should stay all green in every mode, including Silent, without any yellow/red alerts. But the app is designed mainly for audio production, where you need ultra-low latency. For music production, this Asus is basically unusable. For gaming, it’s not as catastrophic as LatencyMon makes it look, but still problematic.

I’m currently playing Dying Light: The Beast and get occasional stutters. Playing in Performance Mode helps, since most of the stutters then feel more like the game engine itself rather than firmware. Still, Asus users do seem to report more stutters compared to others.

So even if it’s not only Asus firmware (Windows updates, Nvidia drivers, or the game engine might also play a role), but based on LatencyMon results it definitely looks like Asus firmware is part of the problem.

Also worth noting: other settings can contribute to microstuttering too – for example, incorrect G-Sync setup, or enabling Nvidia Reflex, which in my testing often caused more hitching across different games. And if you’re locking gameplay to 60 fps, you should ideally match it with a 60 Hz display mode. Of course, if Asus firmware issues are still present, these tweaks won’t magically fix everything, but they’re important to keep in mind.

I dont think the problem from game engine this i can confirm 1 thing i test I bought rog strix scar 18 rtx 5080 new brand after install all drivers and last bios update there was a problem with audio on type c headphone there is high cracking noise and it wont stop on 3.5 it was working well then i bought hyper cloud x 3 wierd when i contacted it as type c the problem started as the same problem i have in new laptop too much random stutter espicially in the witcher 3 cyberpunk borderlands 4 i did a refund for 5080 laptop and bought that g16 5070 ti so the audio problem cause latency moon high dpc and also cause microstutter in games widnows and sometimes mouse freeze while moving in games buzz in audio i hope they fix it soon in my situation i want to refund this one also but i live in syria and there is no other brands to buy now than asus with 5070 ti

Same issue here but with an i9 14900HX and RTX 4080 on an ASUS ROG Strix G18 from 2024. Very disappointed with Asus. They used to be my go-to brand. I have nothing but doubts about them now until they come out with a fix.

[NotPerFect]

I'm not sure how it is on your laptop, but with BIOS 325 (the last working one was 318), Asus broke the brightness controls. The lowest brightness in Eco Mode is now actually brighter than the lowest brightness in Normal Mode… which makes Eco Mode less useful. So yeah, Asus is good at “fixing” things while breaking others – or simply not fixing the real issues at all.

I do think Asus is working on something though, because for the past three months they’ve stopped releasing their own Nvidia driver updates. Right now you can only get them directly from Nvidia, and those tend to be buggy compared to the versions Asus used to test and publish.

[My_Asus_Broke_i]

If you're asking me, then no brightness issues with mine. But I am having all the same issues you are having aside from that brightness issue and fan spooling up.

The stutters are happening frequently regardless of the mode the laptop is in and regardless of the activity. So browsing, gaming, etc. Regular random stutters keep occuring.

I want to change my NVME SSD mode to read and write differently and see if that helps because latencymon identified storport.sys lagging an extraordinarily long time during stutters lasting several seconds.

I also found this article kinda explaining it a bit. Then I gotta find time to do a backup and try this out.  Come on Asus just do a patch.

Since purchasing this laptop, I have been dealing with a problem of intermittent and sporadic system stuttering. The issue occurs randomly while browsing the internet and occasionally when playing music in the background, especially with FLAC audio files, which are more demanding than platforms like Spotify.

​The main problem manifests in games. I have attached a recording demonstrating the effect in Dying Light The Beast: https://youtu.be/OmHj-4ffoxQ?si=vTh7bpCOG2uA9_D4

​Problem Details:

1. ​The stuttering is present in all games once the issue appears.
2. ​Tests were conducted in Turbo mode, plugged in, with no background applications running.
3. ​The only temporary fix is a system reboot.
4. ​The problem can return randomly, especially after exiting a game and switching power modes (e.g., from Turbo/Performance to Silent and back).
5. ​The LatencyMon tool consistently indicates high DPC (Deferred Procedure Call) latency, which suggests a driver or firmware conflict.

​Configuration and Steps Taken:

• ​Control Software: I am currently using G-Helper, but the problem is identical when using Armoury Crate.
• ​BIOS: Latest version 325.
• ​System: Windows 24H2 (latest update).
• ​GPU Drivers: Nvidia 581.29 (installed directly from Nvidia, as the manufacturer's drivers have not been updated for 3 months, and newer games required a recent version).
• ​Other Drivers: All manufacturer drivers are up-to-date via MyAsus.
• ​Additional Tests: Disabling Wi-Fi or Bluetooth does not help at all.

​I suspect the issue may be rooted in the firmware or a faulty interaction with power management drivers, as these symptoms have been present since the laptop's launch day purchase and do not appear to be a typical Windows or graphics driver issue.

Furthermore, I do not understand why, when the dGPU is set as the primary GPU, or when any program uses the dGPU while the iGPU is active, the fans start spinning and do not stop until I close that program. This happens even if the application is not demanding, and the components (CPU or GPU) are barely utilized, with temperatures remaining below 50°C. In my opinion, with the cooling system my laptop possesses, the fans should not engage until the temperature reaches 60°C, just as it happens when I use the iGPU only.

When the dGPU is active, even if I manage to stop the fans by switching between power modes, once the temperature reaches 60°C and the fans start running, they do not stop at all. They continue spinning until I manually disable the dGPU and close all applications running on the dedicated graphics card.

I have also observed that when the dGPU is in use, and an application is set to (or automatically selects) the iGPU, the program becomes severely laggy and unusable. This stuttering persists until I either manually switch the application to use the dGPU or switch the entire system back to the iGPU.

This behavior, described above, has also been present since the laptop's launch day, suggesting it is not an issue with NVIDIA or Intel drivers, but rather with how the MUX switch is managed by the Asus firmware.
