OBS Stream Crashing |60-100% of GPU (prevails after stream)| High CPU usage -> freezes/crashes stream

[niknes]

Hello,

I’ve been experiencing issues while streaming with OBS where my stream freezes or crashes when CPU usage spikes high. Despite extensive troubleshooting, I haven’t been able to resolve the problem and need help identifying the root cause.

I've noticed some time ago, that the GPU usage spikes after some time hits around 65-100% and stays on about 65% even after stream. (Idle after opening about 8% cpu, 17% gpu)

I know with the "source record", and with that recording multiple sources, I am using more resources than normal, but until about 2 weeks ago it has never been a big issue. No spikes, no crashes.

I thought it might be the new game I started, but I reduced the quality without much change and it started happening to other less intense games too.

I checked the OBS analyzer, I hit a Max Audio Buffer with my "Razer Kiyo Pro" (https://obsproject.com/logs/ypqcOu3y7TQEXQt5), but I've seem to have fixed that, without changing the result of this problem...

I changed the multiple game captures (https://obsproject.com/logs/jmjObivE4IuzNCKh), I made my scenes as easy as possible, I removed the "face tracker" plugin (one of the only things I can think of that I changed), made nested scenes easier, put all of my alerts and chats in as little of browser sources as possible.

There are no red nor orange reports through the OBS analyzer now (https://obsproject.com/logs/usO3jU7uBqJc0fFv), but I'm still hitting the highs of CPU (about 40%, bringing my cpu to 100% for some reason) and GPU (as I said 60-100%).

What seems to have been always weirdly high is my average time to render frame about 16.3 ms even if I have OBS open without streaming. (attached)

I left it open while I was gone, maybe this crash report can help too: https://obsproject.com/logs/3RXgrY5RylTRN5Lk


I'm at a loss here and I just want to enjoy streaming T-T

PC Specs:
CPU: Intel Core i9-10900K
GPU: NVIDIA RTX 3080
RAM: 64GB DDR4

I also use Audio Monitor and Move source

I really hope you can help me and I appreciate every idea or help I can get.

Thank you in advance,
NikNes

There's lots o slop in those logs.

Move & Source Record plugins are stale, update them & see if things improve.

Hi,

I updated the plugins, the average render time seems to have gotten down a bit, but there was still a ~99% gpu spike of obs (Up to 70% gpu usage is somewhat fine, after that the frames are dropping fast xp)

Here's the log file https://obsproject.com/logs/23zw92wdOBt7V4rs
I hope there's less slop now tho haha

And thanks for the help ^^

Oh and it very often crashes after closing it normally. It didn't seem to affect much, but maybe there is something up there too

Sounds like there was some improvement but the log ends before you stopped encoding. The tiny tubular task thread crashing is caused by a plugin. Fix the resolution on this encode, maybe it's causing issues with Source Record or the encoder itself.

Tons of SE, java script errors that could be wasting resources. Most appear to be browser sources, cleaning them up would be a good thing to do.

For the encoding, all (8) encodes can be completed with the 3080. Just need to use lower presets. Or you can do some of the encodes with the iGPU to free up some headroom on your CPU.

This is a great reference, check out Table 2.
