Need help with stuttering issues in OBS.

[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.

Looking thru the logs, you have the bitrate set to 6000 kbps. The default is 2500 kbps. I believe that this may cause your preview frame-loss. @fatmatrow

 

These are not related. At all.
