I recently purchased and made the addition to my rig of an Gigabyte RTX 4090 Gaming OC graphics card and I'm experiencing inconsistent frame pacing in the form of micro stutters and some larger stutters in the games I'm playing. So I am posting here to see whether there are any guru's out there who could help me weed out the issue. Firstly my system specs are:
Intel 13900K
Asus Z790 ROG Maximus Hero mobo
Corsair Dominator Platinum RGB DDR5 6000Mhz 32GB
Gigabyte 4090 Gaming OC with EKWB Vector2 waterblock
SoundBlaster X-AE5 sound card
Seasonic Prime Platinum 1300W PSU
Samsung 980 Pro 500 GB OS drive with Win 11 Pro 22H2
Samsung 990 Pro 2TB games drive
2 x Samsung SATA storage drives
Corsair K100 keyboard
Logitech G502X Plus mouse
Alienware AW3821DW 144hz G-sync ultimate monitor
Xbox Windows Wireless controller
The rig is under a custom water cooled loop.
In terms of my own troubleshooting I've been scouring the net but have been unable to find anything yet that resembles the cause of my issue. The game I'm playing and experiencing stutters in is Atomic Heart. All of the professional game reviews of this game say that once the game has pre-compiled shaders it does not stutter. I bought the Gen4 990 Pro 2TB a couple of weeks ago to rule out the Gen3 NVME I had been using for games. The 990 Pro is fast but did not alleviate the stutters.
Just now I have finished doing a fresh install of Win 11 Pro 22H2 onto the 980 Pro. The OS is very lean with just the latest motherboard drivers installed (and BIOS), latest Nvidia drivers, Steam, MSI Afterburner and a clean reinstall of Atomic Heart to the 990 Pro 2TB. I've started up Atomic Heart on this clean Windows install and I would say 90% of the time frame pacing is smooth, but there is still some micro stutters and some larger stutters.
In Nvidia CP I have G-Sync enabled, V-Sync forced on globally and the refresh rate set to 120hz. Everything else is defaults. In Atomic Heart I'm running the "Atomic" preset (which is just max graphics) and I have Nvidia Frame Generation enabled. DLSS is off. In game V-Sync is off. In game fps cap is set to 120, there is no option to turn the cap off.
At this point I think it's still possible for the issue to be something software side in Windows 11, i.e. something misconfigured. My second thought is hardware or the way the hardware is configured in the BIOS. I'm currently running my 13900K as per a popular OC.net tuning guide. I have not stress tested for stability, but I am also not doing any drastic type of overclocking. I have tried the memory on the various XMP profiles and currently have it running at XMP II 6000Mhz.
I noticed the SoundBlaster X-AE5 is sharing an IRQ with the RTX 4090 but I don't know if that could be an issue or is the issue. I'm continuing my own troubleshooting but if anyone here can help it would be much appreciated.

_________________________________________________________________________________________________________
CONCLUSION
_________________________________________________________________________________________________________
Your system seems to be having difficulty handling real-time audio and other tasks. You may experience drop outs, clicks or pops due to buffer underruns. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates.
LatencyMon has been analyzing your system for 0:15:55 (h:mm:ss) on all processors.

MEASURED INTERRUPT TO USER PROCESS LATENCIES
_________________________________________________________________________________________________________
The interrupt to process latency reflects the measured interval that a usermode process needed to respond to a hardware request from the moment the interrupt service routine started execution. This includes the scheduling and execution of a DPC routine, the signaling of an event and the waking up of a usermode thread from an idle wait state in response to that event.

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
Process with highest pagefault count: msmpeng.exe
Total number of hard pagefaults 112
Hard pagefault count of hardest hit process: 67
Number of processes hit: 7

REPORTED HARD PAGEFAULTS
_________________________________________________________________________________________________________
Hard pagefaults are events that get triggered by making use of virtual memory that is not resident in RAM but backed by a memory mapped file on disk. The process of resolving the hard pagefault requires reading in the memory from disk while the process is interrupted and blocked from execution.
NOTE: some processes were hit by hard pagefaults. If these were programs producing audio, they are likely to interrupt the audio stream resulting in dropouts, clicks and pops. Check the Processes tab to see which programs were hit.
Process with highest pagefault count: msmpeng.exe
Total number of hard pagefaults 112
Hard pagefault count of hardest hit process: 67
Number of processes hit: 7
