Issue with high latency after system reboot, NVIDIA driver. Please assist experts.
Hello Guys,
I've noticed some latency fluctuations since installing my 5090 Aorus Master. The system runs smoothly with an 9950X3D and Gskill 6000 MHZ 64GB on cl28 and FCLK 2133MHZ stable, connected to an Asrock X870E Nova with Wi-Fi. All latest bios and expert/general content are up to date. I haven't encountered any problems for the past two weeks.
Until now:
The unusual part is that when I install the nvidia driver without a clean install, just keep installing through the same driver, and don’t reboot, the latency remains very low and stable—almost perfect. It usually stays between 20-30 ms with only minor spikes.

The latency stays consistent until I restart the system. Even when in sleep mode and coming back, it behaves normally, with occasional small spikes. However, once I reboot, the average latency jumps to around 180-200 ms, which is significantly higher than expected.

It seems the issue might be related to something loading from the nvidia driver after a reboot. Or perhaps another service loads only after restarting? I tried everything suggested by YouTube and Google, but it’s proving difficult to pinpoint exactly what’s causing the spikes. It’s been a long process without progress.
I suspect the nvidia app might be involved, as it runs after the reboot, but also the Nvidia overlay. However, maybe another small service isn’t loading until I restart. Disabling the Nvidia overlay and the High Definition Audio & Virtual Audio Device in the device manager didn’t help. Also, turning off the Nvidia audio and virtual audio device didn’t resolve the problem.
I reinstalled the driver again, and latency dropped significantly until a reboot.
Could you help identify what service or conflict might be responsible? It appears the issue isn’t present right after installation but emerges only after a restart. I’d really appreciate your assistance in resolving this.
Best regards.

Recent BIOS updates are important to note.
Is the iGPU turned off in BIOS?

Do you have a link to the RAM kit you're using?
What bothers me is that when I install the nvidia driver without a clean install, just updating the existing one, and without rebooting, the latency remains very low—around 20-30 ms with only minor spikes.
Recommendation: run DDU in Safe Mode to disable all GPU drivers (Intel, AMD, Nvidia), then restart and manually install the newest GPU driver via an elevated command, such as right-clicking the installer and selecting Run as Administrator.
Because you don't require the Nvidia Audio Driver, it's advisable to omit that part from the installation. This driver is often linked with Realtek audio drivers on certain systems and can create issues. Unless you're transmitting audio via HDMI to an external display, you won't need it.
Use DDU to delete the current driver and all related components, then reinstall the newest Nvidia driver—this time opt for a Custom (Advanced) setup. Disable the Nvidia Audio driver, and if you don't use the PhysX driver, also uncheck that one. Also turn off the Nvidia USB-C driver if you're not connecting to an external monitor through USB-C (this might leave a device without a driver in Device Manager, which is acceptable).
Check if this resolves the problem, particularly by removing the Nvidia Audio driver.
Hi Guys.
I need the nvidia HD Audio to be honest occasionally. When I am watching on the TV over hdmi from the computer. But not that often.
I uninstalled it one time in the past, but missed the audio then. So I disabled it in device manager and thought I just re-enable it when I need it. But it did not decrase my latency disabling it.
Ram Kit:
https://www.hardwareinside.de/g-skill-ri...est-72138/
Should be one of the better performing ram kits. Atleast to that time when I bought it, it was on top.
Bios I have the latest from Asrock for sure, 3.50. My 4090 had 1 hour after the bios update an 12VHPWR meltdown. Now I have an 5090 and wait for the repair of the 4090. Which was very weird timing, it had zero issues for 2,5 years of usage. But I can not see anythign related to bios update and 4090 meltdown. Also asrock said that.
But I experience little CPU bottlenecks with my 5090 and 9950x3D. In games where other people have 98-99% GPU usage on 1440p, like red dead redemption 2. I have around 80-90% GPU usage fluctuating, which is not good. This is how I came to this latency topic, because one guy said latency is VERY important for having no bottlenecks.
In CS2 I have the biggest GPU spikes, which I had not with my 4090. I have an 1000W power supply from seasonic prime Titanium TX. my total power draw is around 700W when gaming, so there is enough room.
This is why and how I found out about those latency differences for me directly after driver install, and after I reboot then, how it increases from 20 latency to over 200 base latency. Thats not normal. way worse systems have 50 latency base I saw on youtube. Even with 9900K setups.
I did 2 times DDU and it did not fix it, but It was not in safe mode, just normal mode.
IGPU is disabled, onboard audio is disabled because I got an soundcard. I also disabled bluetooth and wifi, because bluetooth adapters can create spikes sometimes in the timeframe.
And to be honest I did not find or saw ever any nvidia USB driver installation while installing the Graphics Driver to uncheck.
Have you tried any GPU utility tools such as MSI Afterburner? There was a situation similar to mine a few years back. While updating the Nvidia drivers, Evga Precision X1 was still running in the background and once it crashed my system completely. It worked after the driver update but became very unstable right after rebooting. I fixed it by removing both Precision X1 and the Nvidia drivers and reinstalling everything. Afterward, I made it a habit to close the GPU utility app before updating the GPU drivers.
It sounds like you're looking for additional details. Yes, you can get more information about that. Because yes, I am using MSI afterburner and RivatunerStatisticsServer, and HWInfo64 minimized always, to display my CPU and GPU stats in the top left corner. But I have been using those programs without any problems so far. Evga Precision X1 is similar to an afterburner? So you're wondering if you should just try turning off afterburner and RivaTuner? The issue is that all these programs are running at the moment, but when I stay in non-restarting and Windows sleep mode, the latencies are fine. However, I also notice spikes in nvlddmkm.sys:

If you changed the driver while MSI Afterburner was active, it can cause significant issues, particularly when adjusting GPU settings like overclocking or undervolting. Simply stopping Afterburner won't resolve the problem. You need to remove both MSI Afterburner and Rivatuner, then reinstall the Nvidia driver, restart the system, verify everything functions correctly, and finally reinstall Afterburner.
The image after 2 hours appears as shown in the link provided.
It's a good idea to try this out. I usually have afterburner enabled during driver changes, but didn't realize it might affect things. I wonder if storing my settings in the folders will cause any problems with Afterburner and RivaTuner.
I believe the settings files won't cause any issues because they are simply text files the program reads.
Also, I'm not suggesting Afterburner should be installed during driver updates; instead, it should be stopped. However, if you update the driver while it's running and it causes problems, you'll need to uninstall and reinstall everything (Afterburner, driver, Nvidia App).
