Computer Latency Issues, Need help Please!

[Kodin]

Hi All

I have been having problems with my pc, I was playing some GTA 3 Def Edition last night when after about 10 mins the audio started cutting out and my frame rate became choppy, I tried GTA 4 and also sleeping dogs and the same thing happened. I downloaded Latency Mon and I we as getting huge latency so i reinstalled windows 10 pro. Now the latency isn't as bad and the sound isn't cutting out but I'm still getting choppy frame rate. For example i played about 8 mins of Lego star wars the Sky Walker Saga even though the sound was fine and it said on the FPS counter I was getting 130 FPS it still felt choppy.

CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. 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 0:08:16 (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.

Highest measured interrupt to process latency (µs): 2221.60
Average measured interrupt to process latency (µs): 5.605419

Highest measured interrupt to DPC latency (µs): 2211.40
Average measured interrupt to DPC latency (µs): 2.390491

_________________________________________________________________________________________________________
REPORTED DPCs
_________________________________________________________________________________________________________
DPC routines are part of the interrupt servicing dispatch mechanism and disable the possibility for a process to utilize the CPU while it is interrupted until the DPC has finished execution.

_________________________________________________________________________________________________________
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 3942
Hard pagefault count of hardest hit process: 3680
Number of processes hit: 10

Have you checked your thermals, starting with the CPU?

Highest measured interrupt to process latency (µs): 2221.60

This is no beuno... Not sure if the nvidia driver time is ok, but it seemed high. Maybe see if you can find a slightly older version to see if that helps.

Thermals sounds probable, too.

And check event viewer for anything that looks terrible.

It's nothing to do with temps , i cleaned my PC out about 2 months back. Temps are looking fine to me on HW info. How ever please see attached image the top SSD is the one I use for my OS it says it has 54% of life left could this be part of the issue with the NVidia driver latency?

Would i be better off installing windows on one of the 1TB drives?

yes. since you just reloaded, if you have another known good spare drive, try reinstalling on that, even if it is just for testing...
also, if you are reloading, you should disconnect all those extra drives so stupid windows doesnt put the bootloader randomly on to one of them...

• Car Reflections: This is the primary culprit. Setting this to Cubemap or Planar (High) causes massive FPS drops and stuttering. Change it to Screen or Planar (Low) to eliminate stuttering with minimal visual loss.
• World Shadow Quality: High settings here significantly impact performance; lowering this can stabilize frame rates.
• Frame Limiter: The default frame limiter can cause conflicts. Try disabling it in the advanced display settings or capping the FPS manually to 60 FPS via your GPU control panel, as running significantly higher can introduce physics and audio bugs.
• Enable DX12: Add -dx12 to the game's launch arguments in the Rockstar Launcher or Steam. This forces the newer API, which handles the engine's demands much better than the default DX11, often doubling stability.
• Update NVIDIA Drivers: Audio cutting out and stuttering are frequently linked to nvlddmkm.sys (NVIDIA driver) latency. Ensure your drivers are updated to the latest 2026 version.
• Vulkan Alternative: Some users report success using DXVK (a Vulkan translation layer), though this may cause initial stuttering until shaders compile.
• Power Management: Ensure Windows Power Plan is set to High Performance and that CPU throttling is disabled in the BIOS.
• Background Processes: High-priority background tasks (network drivers, RGB software) can interrupt the game thread. Closing unnecessary apps is crucial for this older engine.
• Process Priority: Manually set the game's process priority to High in Task Manager to ensure the OS allocates CPU resources preferentially to GTA III
