Persistent Gaming Stutters on Custom-Built PC (AMD Ryzen 7 9800X3D / Gigabyte GeForce RTX 4080 SUPER)

[wolfitoXtreme]

Hello good people,

Looking for some help here to help me out to identify the root cause of the micro and macro stuttering I'm experiencing, for that purpose I recorded a couple of videos with Afterburner sensor data (you can find them at the bottom of this post), so perhaps someone with the knowledge, based on the numbers can give me a clue of what is going on with my system, whether it is hardware, software, or a combination of both, before proceeding to swap physical components or initiate an RMA if necessary.

The stuttering (micro, macro, and everything in between) only occurs during gaming sessions. I had no other software installed before encountering this issue, apart from IL2 (non-Steam version) and peripheral drivers. The problem was already present, so it’s unlikely to be related to Steam (I later installed other games to test) or any benchmarking tools. I have the same setup on my old PC, where games run much better, albeit at lower graphic settings.

Steps I’ve Already Tried:

 

• Adjusted BIOS settings, including enabling/disabling fTPM, XMP, Resizable BAR, and  clearing CMOS.
• Performed a clean installation of Windows 10 (also tested with Windows 11 Pro, the issue persists).
• Installed chipset drivers directly from the motherboard manufacturer.
• Intalled the game in diferent SSDs, system and storage
• Changed PCI Power Management settings.
• Disabled the NVIDIA audio device.
• Turned off Wi-Fi and Bluetooth.
• Lowered all in-game graphical settings to minimum.
• Switched to a 27" HDMI monitor (1920x1080), which resulted in even way worse stuttering.
   

What I suspect:

• RAM incompatibility, the RAM I bought is not in the Qualified Vendor List,  I haven't experienced any blue screens or system instability so far, just the stuttering. The sticks are configured in dual-channel mode.
• Defective SSD, I encountered similar issues years ago with my old PC with a SATA SSD. I installed the game on both the NVMe 1TB system SSD and the NVMe 2TB storage SSD. I noticed that the 2TB SSD performed slightly worse. However, I ran the WD Drive Utilities on both disks, and no errors were detected.
• I'm cursed by an evil spirit.

I would greatly appreciate your help in reviewing the sensor data visible in the video to pinpoint the underlying issue. Thank you for your time and assistance! .

thanks, 

wolfitoXtreme

Have you tried running the RAM at JDEC specs? Just to rule that out.

[GasTeddy]

I had serious stuttering problems in my, much more modest mill. After downloading ISLC, all that was gone. Worth of trying.

S!

 

Afterburner has caused issues with 9800X3D. I would recommend NOT using anything but essential programs and no overlays etc. 

[69th_Panp]

You should try this program to determine what is causing the stutters 

Intel PresentMon

 

JaysTwoCents does a review and explains how and why its better to use it to find stutters or bottle necks

Doesn't work in VR.

There is a new beta pimax play (1.37.01.01) that supposably fixes jitter issues in VR you may want to try. Just make sure the public test channel is enabled and it will give you a download prompt..

[spreckair]

@wolfitoXtreme  I removed my jitter issues by reducing my per eye resolution in Steam VR from 100% to 98%.  This was after trying all sorts of settings for over an hour.  This was the only thing that worked for me.  I have: Pimax Crystal Light, I-9 14900K, RTX 4080 Super.

Looks promising thanks, will try it out and share here whatever I find. While looking into this one I bumped into an video of an add-on for this very software explaining the process of rendering a frame, very interesting.

Not a distinguished owner of a VR set, saddly, nevertheless seems that what I perceive as micro stuttering is caused by a mismatch between TrackIR refresh rate and the refresh rate of my display https://forum.dcs.world/topic/332556-trackir5-stutter-at-framerates-other-than-60-or-120-fps-in-dcs-28/, these are only happening when I move to view around, not with a fixed view, same in other games. Kinda notticed some improvement playing around with the refreshrate of my display, but stills movements do not feel fluid.

The macro stuttering is present only in IL2.

I know thanks, I experienced the same with or without it

Greetings, Wolfito

 

Just a trail suggestion : have you checked for AMD 7xxx-9xxx x3D core-parking problems ?

You could try switching off e-core affinities, as in my case that worked for my Intel i9 14th gen processors. and DCS

However i don't have problems with IL2.

 

Hyperthreading off, if that's also present for a AMD processor.

I have the same 4080s NVIDIA.

Thanks for the tip, unfortunately id did not help, followed this tutorial...
 

the driver doing that job was already there, by default it seems, so I'm like in the beginning.

not sure about this, I tried DCS as well, hell much worse than IL2, tried both executable versions (Multithreading and the other), but thanks

Before you drive yourself insane or replace parts you should know there's a certain level of stutter in IL2 you can't get rid of linked to the GUI that gets more noticeable with more AI. You might be seeing that if you've already gone to such lengths to remove the stutter.

Have you checked your system with LatencyMon while playing a game? Have you checked that your GPU is set to use message-signaled interrupts (MSI) with a program like MSI util (https://forums.guru3d.com/threads/windows-line-based-vs-message-signaled-based-interrupts-msi-tool.378044/)?

typos, always typos

[jollyjack]

 maybe stupid, but try to exclude (bypass) your entire game folder from antivirus checks.

This fellow tracked some micro stuttering down to using MSI After burner and found a Nvidia advisory ref power monitoring.
