I REALLY REALLY thought I fixed all my latency problems... But I guess not.
So recently I was having major stuttering in games. Big time in PUBG, and some in Apex.
I updated my realtek audio drivers and that seemed to completely fix the issue in PUBG. I figured since it was worst in pubg and is now gone, then it must be gone completely.
But I was wrong, started playing apex the other day and boom getting the same stuttering/ micro freezing that I was getting before.
Let me know if I'm missing anything here in the latency mon test info. For the most part my latency stays low, but randomly spikes up, usually causing frames to stutter.
Heres the latencymon info:

Computer name: DESKTOP-KV3ASTT
OS version: Windows 10 , 10.0, build: 17134 (x64)
Hardware: ASRock, Z390 Phantom Gaming 4
CPU: GenuineIntel Intel(R) Core(TM) i7-9700K CPU @ 3.60GHz
Logical processors: 8
Processor groups: 1
RAM: 16232 MB total

CPU SPEED
_
Reported CPU speed: 360 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.
WARNING: the CPU speed that was measured is only a fraction of the CPU speed reported. Your CPUs may be throttled back due to variable speed settings and thermal issues. It is suggested that you run a utility which reports your actual CPU frequency and temperature.

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): 820.053567
Average measured interrupt to process latency (µs): 3.424657
Highest measured interrupt to DPC latency (µs): 816.924677
Average measured interrupt to DPC latency (µs): 1.293529

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.
