~50% FPS Drops At Random Times, Half-Second Desktop Freezes (Video clips attached)

Hi there,

I've been having this issue for at least 2.5 years now and changing components did not fix the issue.

This happens in 80% of the games that I play, new or old.

Also, even in normal desktop applications this seems to happen.
For example, sometimes if I open a new tab or start typing in Chrome then my PC freezes for what feels like about half a second.
And sometimes the freeze occurs when I open any application. 

Examples of games that this happens in very often: Red Dead Redemption 2, CS:GO, SoTTR, Dishonored, Skyrim, PUBG

Examples of games that don't seem to be affected (limited sample, as this happens in most games): Resident Evil 7, Death Stranding, Hollow Knight

 

Have tried the games on HDD and on SSD, various Windows 10 versions (from 1809 and up)


PLEASE HELP AS THIS IS RUINING MY LOVE OF PC GAMING


Some components in my previous build:

 

Samsung 850 Evo SSD

i7 6700k stock

GTX 1060

MSI Z170A Tomahawk

16 GB G.Skill Ripjaws

Various HDDs


Changed to RTX 2080 and new PSU (Super Flower Leadex II) but issue remained.
 

Some components in upgraded build
1 TB Nvme SSD

Ryzen 7 5800X stock

RTX 2080

MSI MAG X570 Tomahawk
32 GB G.Skill TridentZ

Super Flower Leadex II

Some very short YouTube clips showcasing this annoyance
(Note: these clips were sometimes recorded months apart, from the previous build and the new, across new Windows installations so it's highly unlikely a Windows issue)

Final pistol shot:

 

Right as the dialogue with NPC begins

When sniper unit fires a shot

New Ryzen 5800X PC build:

Dota 2 - clicking on hero causes the lag (also happens in-game with certain actions).

Monitor your CPU/GPU/RAM/VRAM/DISK usage while gaming, these types of stutters usually happen when;

  • Disk is not able to stream assets to ram or vram fast enough.
  • Running out of VRAM and thus assets are extended into RAM (aka "Shared memory").
  • CPU is getting hardware interrupts, again most likely your storage devices.
  • Running out of RAM also can cause this but I highly doubt this is the issue here.

Hi Levent thanks for your prompt reply.

I am going to try those things. My latest suspicion has become disk usage and I am going to try monitoring the DISK usage of all the drives.

Push comes to shove, I'm going to try removing all disks and only running OS and games on the Nvme drive to see if any disks or cables could be causing the issue.

I've never gotten the name of the suspicion I've developed this past week, but I think you nailed it on the head (Hardware interrupts from disks).

So do you think this is a good lead to follow? I was thinking that even though the game could be running on an SSD, faulty hard disks in the system could be causing issues when they are polled.

Discovered the utility LatencyMon and ran a test whilst playing CS:GO and music in the background (WinAmp).

The game did have occasional FPS and audio stutters as usual but my WinAmp never produced noticeable audio stutter.


  

_________________________________________________________________________________________________________
CONCLUSION
_________________________________________________________________________________________________________
Your system appears to be suitable for handling real-time audio and other tasks without dropouts. 
LatencyMon has been analyzing your system for  0:36:33  (h:mm:ss) on all processors.

CPU SPEED
_________________________________________________________________________________________________________
Reported CPU speed:                                   380 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):   558.30
Average measured interrupt to process latency (µs):   4.058705

Highest measured interrupt to DPC latency (µs):       556.0
Average measured interrupt to DPC latency (µs):       1.398821

_________________________________________________________________________________________________________
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):              595.320
Driver with highest DPC routine execution time:       nvlddmkm.sys - NVIDIA Windows Kernel Mode Driver, Version 457.30 , NVIDIA 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:                 csgo.exe

Total number of hard pagefaults                       39781
Hard pagefault count of hardest hit process:          14469

That is certainly weird, as it's supposed to be 3800 MHz
