"You are overloading your GPU and your encoder, at least in parts of the log."
That doesn't surprise me too much. That's a whole seperate issue I'm having. Started happening when I tried to record in 60fps (which I think my PC should be able to handle, but that's beside the point) Obviously recording in 60fps isn't an option for me right now.
"As for the saving... not sure what you're expecting. Flash drives like USB keys are just not as fast as an internal SSD or even a SATA hard drive. They're not suited for realtime recording of HD video."
The thing is I never had problems with it saving within at least 5 seconds of me hitting stop until about a week ago. And this is before I started trying recording in 60fps.
"Are you capturing from a USB capture devices that's on the same USB controller as the flash drive you're trying to save to?"
I'm not sure exactly what this means, but I would guess you mean am I using USB 3.0 or 2.0 for both? If so, then no. The capture card is on 3.0 and the drive is on 2.0. If that's not what you mean then idk.
"You've also got a number of broken image sources that can reduce OBS performance"
I didn't think that could cause any damage, especially considering they're all in different scenes, but if you say so. Most of those are from scenes that I don't use anymore, I just hadn't deleted them yet.
