Persistent stutter issue: tried everything

[fatmatrow]

The issue: a stutter that appears in OBS preview that doesn't immediately translate to streams and recordings at first, but will after a few minutes. It also eventually brings the preview down to 30fps, even though in logs, i have skipped, dropped and missed no frames during these incidents. No encoder overload, no nothing. OBS reports 60 fps the entire time.

Usually, It takes anywhere from 10-45 minutes to appear, stays for different lengths of time, and then may or may not normalize, but will do it again within 10 minutes or so. It happens even without a game running. It does it even when not streaming or recording (i don't do recording much except when i was checking to see if it translated to there too.

Here's the kicker
-This issue presents itself on 2 Computers:
1: Ryzen 3700x, ASUS x570 Tough Gaming Plus Wifi mobo, 3060 TI, 32gb Corsair 3200mhz cl16 ram
2: Ryzen 1700x, MSI B350m Bazooka, GTX 1070, 16 GB 2600mhz patriot ram

I built computer 1 because i thought it would solve this specific problem that I was having with computer 2. It didn't.

Here's a log from my main computer, the ones from the secondary one look the same. Nothing in them indicates a problem:

In order for to expedite this fix, I have written out a comprehensive list of everything I've tried that I could think of. I have spent over 150 hours on this before I stopped counting:

-Tried every capture method, to include using a capture card and NDI: Still present
-All OBS Baseline guides
-Tried an inordinate amount of settings
-Tried multiple encoders
-Disabling preview
-Running/not Running as admin
-Game Mode On/Off
-Gpu Scheduler on/off with mode options for obs selected
-Combinations of the above 3
-Replaced every piece of hardware in my computer, including psu and hard drives
-Checked all connections inside case multiple times
-Checked and replaced cables
-Tried different monitors and external hardware
-Tried with just a single monitor and mouse and keyboard hooked up only
-Made sure drivers and windows were all up to date
-Checked all thermals multiple times
-Checked for throttling issues
-Happens without game open
-Checked resource management
-Tried different bios settings, using pcie3, running completely stock default settings
-Fresh installed windows multiple times
-Tried older versions of obs
-Tried linux OBS, no surprise it did not display the same behavior, so that kind of rules out any ccx issues, but no practical way to use it
-I have tried process lasso etc, manually assigning it to 4c4t
-Various combinations of nvidia control panel settings, windows settings etc
-Ran Latencymon while testing, everything was fine
-Tried enabling HPET, made things worse
-Tried only running 2 sticks of ram
-And More

I really need help with this issue. I will pay $50 dollars to the person who can fix it.

I have the same issue and I've been reading for quite some time. Most posts about this issue revolve around game capture, while for me it's in video playback. What I mean is that I have video sources in my scenes and they are stuttering at random. The kicker is that the stuttering isn't global and it affects the sources individually. Fixing one doesn't fix the others. I'm talking about a 1440p 30 FPS video in a 1080p/30FPS environment stuttering with RTX 3060. The load is miniscule on the computer and even OBS has hardly any load. The issue appears and disappears seemingly at random. I have 3 cameras in the scenes and they never stutter. It's always the video in the preview that's having these issues (and they are translated into the recording and the stream).

I have another (older) computer with an AMD card which streams 24/7 and uses VLC source in order to randomize the video content. The stuttering is present there too and it became a consistent issue after OBS 27.1. I'm desperately trying to find a solution because I'm using OBS in a studio environment and it's a real issue for the end client.

I feel like my issue is related to this old bug, but since it appears in video playback instead of screen capture it might not be the same. I'll make a new post if it's different enough to warrant one.
