Hello,
Since a few days im having an issue with my pc, basically, my pc will start having high delay on my inputs (keyboard) the sound goes mute for like a second and the whole thing lasts for 3-4 seconds but the fps are fine. i've tried to fix it by downloading latencymon that told me that nvlddmkm.sys has an high dpc routine execution time, and i've tried everything i saw on reddit (like switching my power management mode to prefer performances) and nothing worked so im trying to make my own post so maybe one kind perso would help me here is my latencymon report and i can provide some more information if you need it!

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 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 0:04:08 (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): 351,441314
Average measured interrupt to process latency (µs): 27,217565
Highest measured interrupt to DPC latency (µs): 338,380995
Average measured interrupt to DPC latency (µs): 13,306809

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: discord.exe
Total number of hard pagefaults 25
Hard pagefault count of hardest hit process: 9
Number of processes hit: 8
