Non frametime related stuttering.

[sipso]

Hello,

I am struggling with identifing the cause of my issue...

My PC:
Ryzen 7 5800X3D
MSI RTX4070 (regular no super or ti)
Patriot 32GB Ram 3200MHz
MSI B450-A Motherboard
LG UltraGear 34GN850P-B.AEU (3440x1440p, 144hz) monitor.

In most games i cap the fps at a value my PC is able to maintain most of the time as i'm very sensitive to frame flactuations. I guess i never should've went above 60hz to see what's beyond that hill... I have Gsync enabled and Vsync always On in Nvidia Control Panel. Using RTSS i adjust FPS limits for each game. For games that i am able to maintain 144+ fps i have a global 140fps lock set in Nvidia Control Panel (this is mostly for Destiny 2 as this game just doesn't like RTSS and ignores it).


Recently i noticed an interesting and infuriating behavior. STALKER 2, Space Marine 2 and Dragon Age Veilguard, despite having a locked 60fps with a rock solid smooth frametime graph, show stuttering. Now i wish i could record this phenomenon but i've spent my money on the computer and my phone is only capable of recording 30fps and the issue is near impossible to spot that way. Recording the gameplay with OBS or Nvidia App does not capture this issue.

It's very easy to spot this when doing a "spin the camera around with a controller for a smooth motion effect". Except it's often not smooth.

In STALKER 2 i was able to mitigate (i think entirely) the issue by disabling HAGS. Sadly the same doesn't work for Space Marine 2 or Dragon Age Veilguard.

I noticed this usually occurs when GPU usage rises, but i cannot say that's the case for certain.

Does anyone know what i'm talking about and is able to help? I wish i had means of recording this, because i don't even know how to google for this issue. Is there any info i can provide to help diagonose this?

Try troubleshooting using PresentMon (ideally newer versions since they've included GPUWait, GPUBusy or just using the GUI)
Are you sure it's "non-frametime" related? It could very well still be without proper analysis.

I have made some Optimization on my Windows 11 recently (5 videos from "Capet" but it's in french :/, but it is based on FR33THY and others) and all of my latency/framespike/stuttering gone, i think you need to try some optimization on Windows, in the past i was thinking that it was bullshit but not on Win11.

and yet I had a lot of them, I play without e-core with a 13600k OC at 5.3Ghz on all cores (p-cores)

Maybe try this?
