Oops, I meant for steps 3-4.
Interval stutter / jitter / duplicated frames bug - workarounds
- Thread starter wiliextreme
- Start date
Thank for your reply and all of your time!
At the moment I am testing with an Intel B580 GPU So I will not be able to try all of this until I switch back to an NVidia system.
I also gather it doesn't work.
If you can find my recent post under Windows Help you will also see that people are very unwilling to admit any issues or help.
And completely ignore any of my logical questions.
Is what it is and broken.

I've proven over & over that OBS does not cause stuttering issues & have been running stutter free on many systems for over 8 years. If it's stuttering, look somewhere else.
Most of the time, the cause is:
Bad Settings/Configuration/Routing
Rig Issues
Bad Sources
Rendering lag

You can still try steps 7-9 without the nvidia-smi command. However, you have to make sure your GPU's clock speeds are stable and not fluctuating while displayhz.com is open, and also that it stays at that same clock speed the whole time when you're recording.
If your GPU's clock speed was stable at 2600 MHz (for example) while measuring with displayhz, then you need it to also stay at 2600 MHz while recording your videos. Fluctuating GPU clock speeds affect the result you get from displayhz, and a stable clock speed is ideal.

I'd love to see a 1-2 hour uncut recording from your system, captured at 60 fps at 60Hz w/ VSync on a GPU (not capture card) with an RTSS overlay enabled with framerate and frametimes visible in the recording.

Tex, I can record for DAYS without any stuttering. But, you won't see me using a overlay on any of my encodes....

That information about overlays isn't true since RTSS 7.3.2. It added a new setting that fixes any hooking issues when using OBS's game capture:
Game Capture Troubleshooting | OBS
OBS Knowledge Base. If your Game Capture Source is blank, try these solutions first!
Btw, overlay conflicts don't matter if you're using display capture, since OBS doesn't hook into the game in that mode.
Either way, I'd still like to see a recording that's an hour or two long from your system, with or without overlays. An overlay with frametimes would just make it easier to know if your game stuttered or if it was OBS.
The interval stuttering people are talking about here can be easily identifiable a lot of the time, since it almost looks like OBS starts temporarily capturing at 30 fps instead of 60 fps when the stuttering kicks in. It's not a full-fledged "freeze" if that's what you're thinking. There will also be zero dropped frames or any other issues according to OBS when this happens.

Trust me, no stuttering.
You need the help, I don't. Post a log, I'll take a look for you.

Here's a little test I did the other day. The source file I used & my recording can be downloaded. Try the source video as your test, it's only a minute.

A 1 minute test will never reliably reproduce this bug unless you record at just the right time through sheer luck (or bad luck). Depending on your monitor's true refresh rate, it can take at least an hour to manifest. The longer it takes to happen, the longer the stutters are sustained. Some people can see it happen every few minutes at a consistent interval.
Logs won't help, the OP of this thread mentioned this as well, and I've gone through the logs many times myself way before I found this post. The stutters purely exist in the video file itself, OBS does not notice anything. I don't actually need any help, though. I found a workaround, which I posted here already.

Depends, did you try it? Can your system record that without any skips when viewing frame by frame?
I only run 30 , 60, 120, 240 or 360HZ
Errors add up over time, minimize/eliminate the errors & the stutters will cease. Timing is everything.

I'll gladly cast doubt over this statement when I've done virtually everything possible with my setup to get OBS to be smooth in the Projector/Program Preview but it *always* has some sort of stutter whether it be interval or any name that it has. Meanwhile in Elgato Studio the preview is downright flawless without doing anything. The only reason why I don't main Elgato Studio for this is cuz it has gray fills for ultrawides on 16:9 content which don't look that good on OLEDs tbh. But if I'm after a smooth experience I never go for OBS, as much as I would want to.

Hello!
I'm also experiencing this issue.
The frame rate in the recording randomly drops from 60 to 30, then returns. This happens at varying intervals and durations. It seems like if I catch the moment when this effect begins and hold still, it will be prevented. Or maybe I'm going crazy.
If anyone could explain to me what the cause might be, I'd be grateful.
I'd like to know if this problem has a solution without any hassle or anything.
Since I've already determined that the following things aren't related to this issue:
- video card and driver settings
- OBS
- Windows
- monitor frequencies
There is not a single thought as to who could be the culprit.

I'll attach my log, maybe someone can make some recommendations based on it.
https://obsproject.com/logs/2vBOwFr4D9uprkVo
As for the general issue, I think it might be related to vertical sync. I think so because it has the ability to reduce refresh rates to the nearest multiple of 2.
In my case, it might be from 60 to 30, since my monitor has a 60Hz refresh rate.
All I haven't tried yet is building a 2-PC system and using a capture card with buffering.
I have no other options, except maybe getting 120Hz monitors and streaming at 120 fps. However, this will be difficult if you're streaming graphically demanding games from a single PC. Again, a dual-PC setup is required.
I'll have to try this option and live with these FPS drops for a while.
It's also rather strange that some viewers don't notice any obvious problems, according to the survey I conducted.
It's a small sample size, so maybe people just didn't notice them at the time.

I'm pondering the root of this problem. It's that the frame rate in the recording occasionally drops, or multiple duplicate frames appear.
I'm coming to the conclusion that this is a hardware issue, and changing software and driver settings won't help.
After all, programs work as they're configured, and nothing can change over time, especially randomly.
This is due to something like a random change in the monitor's refresh rate or a change in the graphics card's clock speed. But what exactly causes random frame rate changes?
Maybe other people just have different PC builds and this problem is not visible to the naked eye.

Log is incomplete.
You're never going to get stutter free encoding with your settings. Refresh rates @ 175 & 75? Try 120 & 60. Frame-rate 119.xxx? Timing is everything & those those timings don't look so good.
You have sample rate mismatches too.....

There's some slight rendering lag/GPU overload when using the multi-output.
