Probably the most important latency related trick for Nvidia cards is to switch them to low latency mode (and not the ultra one):
Manage 3D Settings/Global Settings/Low Latency Mode -> On.

NVidia low latency mode reduced LatencyMon DPC numbers for nvidia driver from around 600 to around 200 for me, and there was no 3D or video on the screen.
I run GT 1030, because all I need is silent card for dedicated audio workstation to play digital piano VI.
It might be CPU intensive as you say, but I have good CPU.

UPDATE from my post.

For AMD GPU 5500/5600/5700 series, do not disable.
At least not with the current drivers…

The other stuff is ok to disable.

Here MSI for the Realtek audio and NVIDIA GPU was not enabled, the Realtek LAN
was with set to HIGH priority. :o
Here it is not a server, it is now set to LOW :!:
I suspect for your DAW machines you may want to enable MSI for the GPU and
set it to LOW priority.

FIX for USB 2.0 hitching/stuttering on Gigabyte/Aorus B550/X570 motherboards
Disable global C-states in the CPU tweaker menu.
Looks like some new BIOS update fix this.
Here with ASUS B550/MSI B450 no problems...

Today by accident I found 10 scheduled tasks made by NVIDIA. Some of them were set to run 1 hour after the previous one. F*** telemetry etc. The last time I checked this on my old PC (a year ago if not more), I didn't have that much a mess. Maybe because for the first time I tried the studio version of drivers.
Now I need to check what from NVIDIA I'll need for the game engine - with the hope that I need to install driver only.
No wonder that NVIDIA is causing issues. Not only Win10 is full of real-time telemetry, now NVIDIA and probably every driver installed for any device have it too.

The AMD driver is a lot easier to deal with the bloat...

Not sure but I believe the GeForce Experience option in the Driver installer adds most of that bloatware. Either way that Nirsoft app Pictus links to is a great tool to have and it made me remember this app https://github.com/NateShoffner/Disable ... -Telemetry perhaps more convinient for some...

Thanks. Useful tool. I disabled telemetry manually already but it's nice to have tool like this to save time.
I thought that studio version of driver will be free of this crap but I think that it's opposite.
It's so annoying that now for 1 install we have to do 10 uninstalls/disable/delete procedures to clean added bloatware.

I removed the recommendation to disable HPET.
Modern hardware and mainly updated Windows seems not to need to disable HPET.
You may want to test with your stuff and this
https://www.overclockers.at/articles/ti ... dows-timer

To enable back:
- Open cmd as Administrator and type the following commands:
bcdedit /set useplatformclock true
bcdedit /set disabledynamictick no
-REBOOT

Thank you for the great tweaks and informations.

I understand a AMD Radeon GPU is the better choice for an Low DPC Latency Setup instead of an GT / GTX GPU :tu:

What do you think is the best combo:
AMD 3700X + RX 550
AMD 5900X + RX 550
AMD APU (Renoir / Cezanne)

Thank you :tu:

You are welcome, I do not know anything about AMD Renoir/Cezanne.
I had a Ryzen 3600 and now changed to 5600X + Asus TUF B550.
The 5000 series are EXCELLENT!
For my stuff(Photoshop) the upgrade was worth, the 5000 series are very snappy!
I haven't tested much with sound yet :)
I'm not a musician...
