Idk why but i ahve latency problem, I might be sounding like a brat only 500 when others get like 10000 dpc latency, but the problem I'm wondering why I'm even getting 500 when I heard 200 is normal and im post optimizations getting 500... when I see what could be doing it, drivers tab is all good same with cpus tab so very confused.

Here, someone please check this out cause I don't know whats making it go to 500.

Computer name: DESKTOP-9LQS4HA
OS version: Windows 10, 10.0, version 2009, build: 19043 (x64)
Hardware: B450M DS3H, Gigabyte Technology Co., Ltd.
CPU: AuthenticAMD AMD Ryzen 5 3600 6-Core Processor
Logical processors: 12
Processor groups: 1
RAM: 16328 MB total

Reported CPU speed: 3593 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): 553.80
Average measured interrupt to process latency (µs): 6.055958

Highest measured interrupt to DPC latency (µs): 551.80
Average measured interrupt to DPC latency (µs): 4.076281

REPORTED ISRs

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

Driver with highest ISR routine execution time: HDAudBus.sys - High Definition Audio Bus Driver, Microsoft Corporation

Highest reported total ISR routine time (%): 0.003189

_
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): 90.586140
Driver with highest DPC routine execution time: dxgkrnl.sys - DirectX Graphics Kernel, 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.


Process with highest pagefault count: none

Do you the latest chipset driver?
How hot is the cpu getting?
Play with the windows power plans/settings....test.
`
i think I'm on the latest chipset updated it a week ago same with bios, I tried balanced ryzen its same and cpu is around 84 c in aida but when gaming i think its 65~ c
