Question / Help Laggy Recording but in-game FPS is fine

MineKnights · Aug 1, 2017

Whenever I record with OBS, my game runs perfectly fine, but when I play the recording, it seems to stutter often. Anybody have any ideas?

The log you posted looks fine. Did you try playing the recording with a different media player?

___Maggi___ · Aug 2, 2017

Isn't 50000bitrate a little bit high? Never tried it, just an idea.

If you have enough disk space available you can also try another recording option. I record with CRF instead of CBR. If you want, give it a try :-)

The default value for CRF is 18. The lower the value the better the quality but also the bigger the file. I'm fine with CRF 20.

Yes I've viewed it in different players. Heres a gameplay is on YouTube and you can tell that the frames aren't consistent

Here you can see the recommended bitrates for a youtube video upload: click

Either you lower your bitrate or try CRF.

I can't tell you other possibilities. Maybe other people can suggest better solutions.

always enable vsync in game if you stream/record
recording with cbr is bad idea. go with attached picture if you want to keep using nvenc.
x264 crf +game can be too much for this cpu

Wouldn't V-Sync make my recording laggier since it is limiting my in-game FPS?

no, you need vsync to limit game so it wont max gpu. obs uses gpu also and if its maxed it cant grab frames well resulting in stuttering.
even minecraft will max gtx 1080 with 1000fps without vsync but you need only 60
