ACPI.sys with highest execution (ms) on Dell G5 15 5590

O mouse e os vídeos na Internet chegam a travar em certos momentos, mesmo tendo o plano de energia configurado para Ultra Desempenho.

Utilizei o programa LatencyMon para saber o que está provocando essa latência alta e o resultado foi o driver ACPI.sys.

Todos os drivers mais recentes lançados pela Dell até hoje já foram instalados.

Alguma dica de como diminuir essa latência?

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 0:08:00 (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): 75428,20
Average measured interrupt to process latency (µs): 26,645696

Highest measured interrupt to DPC latency (µs): 75417,30
Average measured interrupt to DPC latency (µs): 14,912946

_________________________________________________________________________________________________________
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): 88256,932870
Driver with highest DPC routine execution time: ACPI.sys - ACPI Driver for NT, Microsoft Corporation

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: brave.exe

Total number of hard pagefaults 837
Hard pagefault count of hardest hit process: 160
Number of processes hit: 51
