The reason I'm posting this in Graphics Cards forum is because the issue seems to be pointing to my gpu, or at least the drivers for it. But if it's the wrong forum perhaps the thread could be moved elsewhere?
It's a week old PC build. I'm experiencing regular high latency spikes as reported by Latencymon, the report from the PC loading + some gaming time + some idle time is included below. So far I managed to pinpoint the spikes particularly to when I open an app, any app, be it Steam or Notepad or a game. They also can happen on idle when literally nothing is happening on the screen and there's like just one browser running in background, although in this case they're much rarer.
When I launch an app, there's a latency spike 8/10 times. Same happens when I change the windows size by dragging the corner of it in some apps (random observation lol). Now whether these spikes coincide with some stutters or audio pops, most of the time the don't. I do have some occasional mini-stutters, both visual and audio ones, and the apps seem to be taking a bit longer to start than I'd expect from such a PC, but I can't say it's even that much noticeable. Like if I didn't decide to do Latencymon, I'd probably just write if off as "just Windows things".
My in-game performance seem to be pretty normal so far as well. It's hard to tell when a stutter happens due to the game or some other factor or this latency issue, you know. But I didn't really game much so far at all. I'd say though that in the games I tried so far (Apex, Death Stranding, several hours of Monster Hunter Wilds benchmark) I didn't experience any heavy stuttering or micro-stutters or audio issues. I've also been playing music in the background while playing said games and the audio's been... fine? Not sure what to make of this or how to test this issue properly tbh, maybe y'all could help me with this.
Mobo - MSI MAG X870E TOMAHAWK WIFI
CPU - AMD Ryzen 7 9800X3D
GPU - Inno3D GeForce RTX 5090 x3 OC
RAM - G.Skill 64 GB (2x32GB) DDR5 6000 MHz Flare X5 (F5-6000J3636F32GX2-FX5)
PSU - NZXT C1200 Gold ATX 3.1
SSDs - Samsung SSD 9100 PRO 1TB in M2-1 slot (the system drive), Samsung SSD 990 EVO Plus 1TB in M2-3 slot, Samsung SSD 990 PRO 2TB in M 2-4 slot, plus a SATA Seagate HDD
OS - Windows 11 Pro with all latest updates installed
This is what I tried so far:
Each of these steps were the possible solutions I came across by googling this issue, as reported by other users and "experts". In my case, none of these changes helped much, and the latency behavior seems to have remained more or less the same, with only barely noticeable improvements.
Then I tried disabling the 5090 in Device manager and switched to the onboard AMD graphics. The latency went to normal, no spikes, all in the green (although the 'Reported total hard pagefault count' numbers were also on the high end on AMD graphics, but everything else looked normal). But the moment I enabled my 5090 again, the spikes are back.
The temps are all normal. Everything is seated properly. The PC seems to be stable, I've been stress-testing and benchmarking it for the past week. This latency test was the last one I wanted to do... As far as overclocking and such goes, I have Expo profile 1 enabled for RAM, PBO -25 on all cores +200 boost for cpu, and an undervolt curve for gpu.
During my searches for solutions, I also ran into a 30+ pages long thread on some other forum for this exact issue, and according to them there are driver bugs with Nvidia and Windows that make this issue unsolvable, unless Nvidia fixes it with new drivers. The thread has been closed two years ago with no resolution though, and it was focused on older Nvidia gpus in the first place, not the 5-series, but perhaps the bugs are still there and that's what affecting my system?
What else could I try doing here? I'm kinda paranoid that it might be some hardware issue more than anything, but would also love to solve this of course. Thanks in advance for your help.

OS - Windows 11 Pro with all latest updates installed
This is what I tried so far:
- Reflashed the latest BIOS
- Reinstalled chipset drivers
- DDU uninstalled Geforce drivers (including the Control panel settings), installed the latest Geforce drivers
- The gpu was already in MSI mode, but I also put the interruption setting to "high"
- Disabled High Precision Event Timer
- Disabled Global C state control in BIOS
- Uninstalled and reinstalled VC Redist
- Changed Pagefile from automatic size to 96-128gb
- Changed some power management settings: Link state - off, USB selective suspend - off, Processor Idle Demote Threshold and Processor Idle Promote Threshold - 100%
- Switched from Diplayport cable to HDMI cable
- Disabled Gsync
- Disabled the framerate "overclocking" feature on my monitor that allowed to bump the framerate to 165, and set the screen framerate to 144
- Reset the gpu undervolt in MSI Afterburner
- Ran Latencymon without MSI Afterburner or HWinfo running
- Unplugged my external DAC I'm using for audio (Khadas Tone 2 Pro) and tried using the onboard Realtek chip for audio
- Plugged my external DAC into a different USBc port
- Changed PCIE-1 Gen from auto to Gen 5, changed M2-1 Gen from Auto to Gen 5
