incredible poor latency HELP!!!!!

HI I am havinf extremely poor latency and dell support are not really helpful

i dont understand why after so many years the same problem exhists, its not that hard dell get your engineers to fix the latency problem for once, the laptop is so close to being perfect 

here is my the report from latencymon 

_________________________________________________________________________________________________________
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 1:24:33 (h:mm:ss) on all processors.

SYSTEM INFORMATION
_________________________________________________________________________________________________________
Computer name: DESKTOP-41SOB4R
OS version: Windows 10, 10.0, version 2009, build: 19042 (x64)
Hardware: XPS 17 9710, Dell Inc.
CPU: GenuineIntel 11th Gen Intel(R) Core(TM) i7-11800H @ 2.30GHz
Logical processors: 16
Processor groups: 1
RAM: 16107 MB total


_________________________________________________________________________________________________________
CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed: 2304 MHz

Note: reported execution times may be calculated based on a fixed reported CPU speed. Disable variable speed settings like Intel Speed Step and AMD Cool N Quiet in the BIOS setup for more accurate results.

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): 24076.40
Average measured interrupt to process latency (µs): 4.572365

Highest measured interrupt to DPC latency (µs): 24065.30
Average measured interrupt to DPC latency (µs): 1.953186


_________________________________________________________________________________________________________
REPORTED ISRs
_________________________________________________________________________________________________________
Interrupt service routines are routines installed by the OS and device drivers that execute in response to a hardware interrupt signal.

Highest ISR routine execution time (µs): 555.919271
Driver with highest ISR routine execution time: ACPI.sys - ACPI Driver for NT, Microsoft Corporation

Highest reported total ISR routine time (%): 0.002364
Driver with highest ISR total time: ACPI.sys - ACPI Driver for NT, Microsoft Corporation

Total time spent in ISRs (%) 0.003756

ISR count (execution time <250 µs): 310047
ISR count (execution time 250-500 µs): 0
ISR count (execution time 500-1000 µs): 133
ISR count (execution time 1000-2000 µs): 0
ISR count (execution time 2000-4000 µs): 0
ISR count (execution time >=4000 µs): 0


_________________________________________________________________________________________________________
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.

Highest DPC routine execution time (µs): 72954.317708
Driver with highest DPC routine execution time: ACPI.sys - ACPI Driver for NT, Microsoft Corporation

Highest reported total DPC routine time (%): 0.028671
Driver with highest DPC total execution time: Wdf01000.sys - Kernel Mode Driver Framework Runtime, Microsoft Corporation

Total time spent in DPCs (%) 0.077654

DPC count (execution time <250 µs): 2194689
DPC count (execution time 250-500 µs): 0
DPC count (execution time 500-10000 µs): 23615
DPC count (execution time 1000-2000 µs): 4
DPC count (execution time 2000-4000 µs): 0
DPC count (execution time >=4000 µs): 644


_________________________________________________________________________________________________________
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: dellsupportassistremedationservice.exe

Total number of hard pagefaults 145530
Hard pagefault count of hardest hit process: 41893
Number of processes hit: 181
