Extrem Frametime Spikes

Manchmal · February 9, 2023

Hello Troubleshooting and Performance Experts,
Iam experiencing a few problems while Gaming with my RIG:

i7-10700k with Artic Freezer 2 240mm
RTX 3060 Gainward Ghost
MSI Z490 Plus ms-7c98
Ripsaw 3600Mhz CL16
beQuite Straight Power 11 750w
Samsung 980 NVME M.2 1TB
Gigabyte xxxx NVME M.2 1TB

Following problem occurs in every Game:
My FPS are pretty high aswell as GPU and CPU usage but every now and then between 15-60seconds a random spike happens. My FPS drop and my frametime skyrockets resulting in a short but very noticable lag/freeze.
Sometimes but only once every like 5hours of gaming and only with certain games i get a weirds soundbug and freeze. (This might be a differnt topic so feel free to ignore it as it is no problem at all, I just wanted to state every info i have)

Graph1 Overwatch 2 capped fps 144 https://ibb.co/Tm7nq3f
Graph2 Overwatch 2 uncapped https://ibb.co/KbKRmN2
Graph3 Diablo3 uncapped https://ibb.co/pbvZ1tp

Also happens in every non-Battle.net Game.
As you can see it seems pretty smooth and fine until a big spikes comes along and ruines my experience.

What i have tried so far:

Swapping SSD
Swapping RAM and RAM slots (currently a2/b2 again)
Swapping PSU
Disable HPET
Chaning GPU CPU Prio via regedit (and reverted)
Reset BIOS
Update BIOS
OC CPU
Disable C-States, HT, Intel Speed Shift, Turbo Boost
XPM on/off
Enable Rez Bar
GameMode on/off
Disbale GameDVR
GPU scheduling on/off
Changing Powerplan to High and Ultimate Performance and also changing it to 99% CPU Power
Reinstalled Win10Home
Reinstalled Win10Pro
Windows Updates
Update all Drivers, Display, Audio, Intel, Chipset etc. Everything. (GPU with DDU, 5-6 different drivers)
Cap and Uncap FPS with RTSS, Nvidia Control Panel, ingame, Vsync
Change Nvidia Control Panel to every possible setting and back
Disable both Root Enumerator in Device Manager
Uninstalled every non-essential App
Disabled Win Telemetry and allother non-essential Services including Microsoft Services
Undervolt GPU

unplugeg Front USB Panel Connector

tried running ISLC while gaming
latencymon is fine
temps are all fine (tested with lots of configurations, nothing even close to critical)
disbaled spectre/meltdown mittigation
Disabled TPM
Changed GPU to MSI (Line based Interrupts)
Disabling Sound Drivers

Maybe i also tried other things i might have forgotten.
I would like some advice on what i could try or on what tool i could get/buy to analyse the cause of the stutter. I tried MSI Afterburner, FrameCap, PerMon, LatencyMon hwinfo, hwmonitor) to find out the correlation betwenn the spike and some latency (driver mabe) , currently iam testing Nvidia Nsight System but iam a bit lost.
Any way to find the reason and/or tools debug this?
