I have posted this in the NVIDIA developer forum. I think it is a driver bug that needs to be fixed. Even though it does not affect the majority of users, i think that i am not the only one who is pissed off, since the driver upgrade caused me to spend many unhappy hours and lots of frustration.
Discussion: NVIDIA Display Driver (nvlddmkm.sys) DPC Latency
- Status
Installing 512.95 right now and will report back how it is for me.
Yep, I can also confirm 512.95 is not worse than the 4xx driver I've installed before. I've also installed GFE, PhysX and the HD Audio driver just to make sure those have nothing to do with the latency - they have nothing to do with it.
And it's not like it wasn't like this before. Googling a lot reveals that this problem is popping up from year to year with different driver versions and after fixing it they forget about it existing and when it pops up again, for a while they just don't give a freak about it again.

What type of audio interface?OMG. I can keep my beloved audio interface
Not many views at the NVIDIA forum so far.

I‘ve signed up on these forums as this seems to be the only place talking about this issue seriously. Thanks I’m advance to everyone for the input so far, I’ve learned a lot trying to tackle the issue on my end but no joy yet. I’m getting mostly the stuttery audio with pops and crackles and erratic mouse moment.
I’m using an Aorus B550i Ax Pro WiFi with Ryzen 7 5800, Nvidia 3060ti and 32GB.
I’ve attempted running various versions of the nvidia drivers, not finding one that works yet. On my end, even with the nvidia driver uninstalled, I noticed a driver called wfd01000.sys wracking up a ton of interrupts. Other than that, the several other drivers (ndis, acpi etc.) go a bit crazy with the latency, but the nvidia driver exacerbates the issue most.
On my end it partially seems like WiFi 6E/Bluetooth driver (RZ608) when loaded/used also seems to make the issue worse.
I’ll keep trying more and keeping an eye on these forums. I’m at my wits end at the moment as I’ve lost enough hours over the last week on this uninstalling, rebuilding, doing MSI, and interrupts etc.!

trying some of the tricks here has ruined my audio, LaMon warns me about not being suitable for realtime audio but on a normal(just tweaked or standard install) LaMon is quite happy.
i have to use audacity and ffmpeg to convert mkv and ac3 but i render into mp3 or wav with reaper.

I'd like to clarify Nvidia driver version discussions real quick:
Nvidia driver numbers are not universal. This is because when Nvidia releases driver updates they don't release a new driver for every card they've made, or even every card in a series. What this means is, if someone says "Version 999 has no issues for me" it isn't always going to be relevant to every person. To accurately discuss driver versions we must include all of the following details: Card, OS, Variant (GameReady/Studio), and Version. I.E. GTX 670, W10 64-bit, Game Ready Driver, 474.14
So when someone says "512.95 has no issues", it's meaningless to some of us, because our drivers don't even go up to 500 yet. Just something we need to keep in mind, and be more specific about in future posts to prevent confusion.

Tried this driver, and didn’t work for me. After around a minute, DPC for the nvlddmkm.sys hits around 1485 which appears around average for my system.

Yes, very important point to discuss. This is why I try to test everything everyone is posting and get the results up as soon as I can, because I don't want a bunch of members and lurkers applying stuff that will make their peformance worse. Let me put it this way, I have not set aside a single tweak from this entire thread to use in my own gaming machine. Almost all of them are either highly situational, do nothing, reduce performance, cause bugs or quirks that outweigh benefits gained, or they just don't do what people think they do.
There are a few exceptions, but I already use them before I started this thread or had them on my todo list to incorporate into future images on my machine. Offhand, the ones I can think of that fall into this category are the spectre/meltdown CPU mitigations that AeonX posted, the promote/demote power plan stuff that I and Necrosaro discussed, and I'm probably missing one or two more. The point is everyone in this thread should be careful and not just assume that every tweak here is good. Test everything yourself and use tools to get real data on whether or not they benefit you, not just "feel". Treat this thread like one giant testing/brainstorming session, it's not a thread of "all this stuff can improve performance".
Hellbovine dont forget we have a side step here for power settings too.
windows 7 x64 bareboned down to 1.26(.16?)gb installed made for a very good offline daw/audio editor and playback machine.
on 7 and 1809, barebone services(offline) scheduled tasks, disable logging and hogging windows flatlines in less than a minute on task manager and it feels fast without all th ebackground stuff going on.

This is one of the best most up-to-date drivers. More stable and with more FPS.
497.09 and 461.92 are other good ones. 522.25 looks good too (had performance improvements for DX12 games).
Edit: I changed the first link, I didn't realize that at 1440p the Ryzen 5600X is causing a bottleneck on the GTX 1080 Ti
I changed it for the 4K test.

Usually not, but there are always improvements and bug fixes that cover all supported cards. Hardly do you see improvements for a specific card, only in some cases when a very specific bug affects only one model of card.
