Question / Help Recording at 120 FPS and Rendering at 29 FPS

[Forward Gamer]

I use obs to record my gameplay, and I record at 120 FPS, with my games running at 120 FPS. When I record, obs tells me I am recording at 120 FPS, however, When I view the video afterwards, It is very choppy, and it says it is recorded at 29 FPS. Attached is my latest attempt to get 120 FPS. still got 29.

That log is from SLOBS.
We do not provide support for Streamlabs OBS here. You need to go to the Streamlabs forums for support with their software, even if it is based on the OBS Studio codebase.

I have swapped over to OBS from Streamlabs OBS, and am getting the same error, with the error message: "encoding overloaded! consider turning down video settings, or using a faster encoding preset." In task manager, recording minecraft, my CPU usage never goes above 45% and my GPU usage never goes above 50%.I apologize for posting on the wrong forum before, and am now using OBS. I have changed various settings, and always get choppy video and a encoding error. For most of my tests i used x264 with Rate Control CRF 15. I can give any other details if needed.

When the logfiles say this... they're right, no matter what task manager says. You're not even particularly close to being able to do it.

1050p144 is too much to encode at this preset. You're overloading the GPU just rendering it. Lower the framerate or use a faster preset.

Recording above 60fps is outside the standard supported use case, and is at-your-risk.

Drop the recording framerate to 60fps and try another recording, if it is still having render delay/encoding overload, post a new logfile from the new recording session, and we can advise further.
