Question / Help OBS Freezes and then whole PC lags

[SnoringNinja]

So, I'm having this fun little issue, and I'm pretty sure it's due to my GPU possibly having issues, but figured I'd be better suited to ask here before I go and shoot Asus support an email.

What is happening is that during the stream, eventually OBS seems to "die" and the rendering lag starts to skyrocket. When this happens, the entire computer gets all laggy and unusable. Sometimes OBS will recover, but generally it does not. Now, for the last few months I was using 23.2.1 and a GPU driver from February, but I finally updated both. Immediately I downpatched OBS back to 23.2.1 due to issues, and things had been fine until today. I've attached the log here, and am hoping someone can provide some insight to the issue (please remember I've tried latest OBS, and I immediately had issues that I did not have on 23.x).

This is a dedicated streaming rig (2080TI, 3960X, 64GB RAM).

Thanks all.

What is your actual reason for reverting back to 23.2.1?

Nearly all of your lagged frames are due to rendering lag. 24.0.3 added a key feature that addresses this -- running OBS as administrator will add OBS to the GPU priority list, which will allow OBS to get the necessary resources it needs for scene rendering with other things like game rendering happening along side.

One of things you can fix is your audio coming from the Camlink:
20:51:45.779: Max audio buffering reached!
20:51:45.779: adding 853 milliseconds of audio buffering, total audio buffering is now 960 milliseconds (source: Camera)

You don't need to capture audio from the camera. Mute it and in Audio monitoring, set it to Monitor Only (mute output) and have no tracks selected. I never capture audio from my camera that is attached to the Camlink. There's no point if you already have a mic in the same room.

Here's what my Advanced Audio looks like:

Why are you trying capture at 1920x1080 @144FPS while you are streaming? You are pushing out to Twitch at 60 FPS. There is no need to capture 144 frames. All the extra frames are just making your system do more work and will be ignored.

My concern isn't with the rendering lag in the log as that is a result of the skyrockets from 0 to insanely high when this issue kicks in. Until that happens, the only rendering lag that shows is from when I start OBS. I don't have logs from when I was using the latest OBS, but the general gist of things is that this issue was happening far more often when I was using that version versus 23.2.1. If I get some time this week, I'll update OBS and give it another whirl to see what happens / get a log.

Thanks for this, guess I missed that that was a thing.

I can't remember why I had it this way, but I can try dropping that down to see what happens.

Hi I saw you answer.
I am using a Sony Camcorder and Avermedia LGP Lite.
The question is: How Can I disable the "using video device audio" in OBS from this Camcorder?

Let's go to VMIX, it doesn't happen there.
Here support does not answer this problem that has been around for a long time and nobody solves it!!
Terrible
