Question / Help Stuttering while recording

[RioT1133]

When i am recording, the output is really bad (15-40 fps), yet in game is constant 144 fps

log: https://gist.github.com/dd0a73c4cd890f3a8d9d4dfad7421b14

setup: i5 7600 (non-k)
1050 ti
8gb ram

displays
1080p@144
1080p@60

any help is welcome

You need a complete stream or recording session in your log. Your log has nothing but startup and a bunch of errors relating to try and game capture Geometry Dash.

15:53:47.911: [game-capture: 'Game Capture'] attempting to hook process: GeometryDash.exe
15:53:47.927: [game-capture: 'Game Capture'] capture stopped

this should have the recording session in it: https://gist.github.com/anonymous/504bc13b5c79147809fd93c9316cb2f3

Yes. For one minute. If you don't experience the problem you're trying to address during that time, there won't be anything in the log about it.

Here's your recording session in the log:

You dropped some frames, but it doesn't say why. It seems likely that whatever interval OBS is monitoring what is going on, it's not catching the reason while it's happening.

That said, the usual advice there is to either lower captured framesize or framerate, or use a faster CPU preset. Adjust those three values until you can capture smoothly at the quality you want.

How much is some, because the recording was really stuttering? I am using the nvidia encoder so i cant reduce the cpu preset

 

[RioT1133]

And i reduced the GPU preset to "High Performance" and the quality to 720p30 and it still stutters

 

[Narcogen]

It may just be that NVENC isn't providing the information about why frames are dropping.

What happens if you use the x264 encoder?

 

[RioT1133]

Same story, in-game framerate is lower

 

[Narcogen]

Yes, but now you can adjust the CPU preset, and the log should tell you whether frames are dropping due to rendering lag, encoding lag, or network lag (only for streaming).

 

[RioT1133]

i set the preset to ultrafast, the in-game frames got better, but the recording still was stuttering

it says here it dropped only 8 frames, but the framerate was constantly at 40-ish

Also, what i noticed is that obs uses only 10% of my gpu when im recording with the nvidia encoder
