rdalcroft · 8 days ago I have a few suggestions for you. This driver is no worse than the previous drivers. I can get a stable 200us in DPC LatencyMon using the below list as Guidance:
Disable HAGS (Hardware Accelerated GPU Scheduling
Disable both 'PEG - ASPM' / 'PCI Express Clock Gating' and adjust other related features (credit Astyanax) if supported in the motherboard BIOS.
Setting the Min Vram clock frequency to 810mhz using Nvidia Power Management utility. See here for Guidance: https://forums.guru3d.com/threads/nvidia-power-management-nvpmm-nvidia-power-limit-profile-nvpl-profile.447584/page-3
Windows power plan:
a. A Balanced power plan at (5% min and 100% max) will give you much Higher DPC Latency numbers 600-2000us+ Unstable
Try setting your Min to 40% and Max to 100%. = 250 - 300us stable
b. High/Ultimate Power plan will give you a steady 200us Stable.
- You can even set your GPU power to Max Performance (on a per game basis, using Nvidia control panel, setting a custom power for each game profile. I do not recommend setting this in the global setting).
Be sure you are not confusing game stutter, for DPC Latency. Latency may cause slight audio stutter, maybe mouse stutter. But for it to actually cause graphics stutter, the reading would have to be severely high like 5000+
Usually going from a Balanced power profile to High/Ultimate will eliminate most stutters in games, as the CPU will not down clock while gaming.
This is usually more noticeable on games which do not fully utilise the CPU, thus letting the cores down clock. The stutter happens when the CPU is called back into use, and there is delay in the CPU ramping back up to full usage.

I used the Interrupt Affinity config tool to have my audio interface use CPU core 6. I then used DDU to remove the nvidia drivers and reinstalled the driver with nvcleanstall.
I installed the driver with these tweaks:
-Disable installer telemetry
-Unattended express installation
-Expert tweaks
-Disable driver telemetry
-Disable hd audio device sleep timer
-Enable message signaled requested
-Interrupt policy - specified processors
-I selected core 7
-Interrupt priority high
-disable hdcp
I went from live 11 essentially being unusable due to the audio dropouts from DPC latency to being able to run my Motu m6 at 48khz at 64 samples with no audio dropouts or glitches. I do not know how this will affect gaming performance as I use my rig for audio production mostly.
