High Latency on NVIDIA Windows Kernel Mode Driver

Hi, recently my PC has started to run games very poorly. This happened out of no where and ive tried everything I could think of. Usually I run GTA5 with 200+ fps but now its running 30-50 fps. This is happening in other games too. I cannot find the problem that is causing this. Ive tried running LatencyMon to see if could find the problem through there.
I found that my "NVIDIA Windows Kernel Mode Driver" (nvlddmkm.sys) is running on a very high execution time (μs).

Theres not a lot of help to find on the internet about this problem, atleast not anything that seemed to help me out.

All of this happened after I updated to Windows 11. Ive now gone back to Window 10 but the issue is stille there

Ive put the report text below

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 0:02:02 (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): 1410,30

Average measured interrupt to process latency (µs): 8,136864

Highest measured interrupt to DPC latency (µs): 1406,0

Average measured interrupt to DPC latency (µs): 4,045040

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 76

Hard pagefault count of hardest hit process: 42

Number of processes hit: 10
