Micro Stuttering, Micro Stuttering Everywhere

[Pterodacton]

Hey guys,

Not sure if I'm on the right forum, but I'm having massive issues with micro stuttering.

I've just built a new computer in the past month, specs are:

• MSI Z790 Tomahawk WiFi motherboard

• Intel Core i9 13900KS

• Corsair Vengeance 64Gb 6600Mhz

• 2TB WD Black SN850X NVMe SSD

• Asus TUF RTX4090

• Corsair HX1200 PSU

• Dell S3222DGM monitor

Performance is - obviously - quite good, however I've noticed micro stuttering, I've always been more susceptible to it over framerate, I've been able to tolerate 30fps console gaming for many years but if a game has uneven frame pacing then it's basically a deal breaker for me, I initially thought it was my mouse movements, but plugging in a controller and smooth panning the camera shows it, so I think it's something else. The monitor is freesync premium, which is supposed to be compatible with gsync.

Things I've tried so far are, disabling e cores, disabling resizable bar, limiting the framerate in the nvidia control panel, disabling reflex boost, all combinations of gsync, freesync and vsync on and off, but no matter what I do, I can still perceive stuttering.

I downloaded the nvidia pendulum demo, and even at 165hz, with gsync enabled, with MSI afterburner showing smooth frame rate and frametime graphs, I can still see stutters. I've even filmed it in slow motion on my phone to make sure I'm not going crazy, but the truth is that the stutter is everywhere, even just moving desktop windows around, it's everywhere.

I'm at a complete loss here, does anyone know anything that might help?

try
disable freesync premium in the screen settings

enable gsync apply then disable gsync apply

is it with dp or hdmi ?

did u install the cheapset driver ?

Have you tried at a lower refresh rate? It could be a bad monitor that's stressing itself at max refresh rate. With microstutters, I'm lead to believe there's either something wrong the vsync/gsync setting or the monitor. For me, I had micro stutter issues in Saints Row 4, and I fixed it by forcing vsync in Nvidia control panel.

I've tried what you suggested above, it's display port, and the chipset driver was installed.

Yeah I've tried all the usual refresh rates, I've been frame capping my games at about 80fps, I've been able to max out games with comfortable overheads, I even created a custom resolution with 80hz fixed but still seem to get this irregular movement of things moving on screen, even when the frame rate and frame time graph are flat lines.

I'm going to try plugging my PC into my TV and see what's what.

Could you send the video you took with your phone?

Sure thing, I deleted it but I'll make another as soon as I get the chance.

Here it is, unfortunately the whole video is slow motion rather than just the end like I intended, so feel free to skip ahead.
I show that the g-sync indicator is on, that I'm limiting my frame rate to 80, and that the monitor is indeed at 80Hz, the frame rate and time graphs look smooth(ish) at the end I zoom out and show the whole monitor and the light grey bar skips unevenly across the screen, this is visible to the eye though obviously not as pronounced as the slow motion shows.

Also, ignore the GPU being at 100%, it's a 4090, it stays at 100% regardless of the frame rate I think it's just how the pendulum demo works as I get the same issue in games that barely use 30% and don't even trigger the fans spooling up.

Try doing a clean install of the Nvidia drivers and run a benchmark in safe mode. That way, you could rule out anything running in the background. Wish I could be of more help.

you are unstable
disable cstate
set 6000mhz change nothing else in ram
set fixed cpu pcore and ecore speeds on 54 and 38
and disable hyperthread
