Question / Help FPS drop on OBS while streaming - i9-9900K RTX 2070

[OLAF_SAVAGE]

Here is a clip where I stream my second screen /streaming my obs screen and open my game on the other. Look at the fps drop and that

Here is the log for that stream https://obsproject.com/logs/xjsTtjNJlsGigga4

There's no output session in that log.

21:25:48.027: Output 'adv_stream': Number of lagged frames due to rendering lag/stalls: 602 (10.0%)

Rendering lag caused by GPU overload.

Also looks like you have a misconfigured ffmpeg option.

21:23:45.671: YUV mode: 709/Full

You may wish to change the above to 709/Partial.

21:23:49.338: - filter: 'Color Correction' (color_filter)
21:23:49.338: - source: 'Display Capture 2' (monitor_capture)

It's not recommended to have Game and display captures in the same scene.

But why does it do that. i stream over my CPU and my graphics card is pretty good? :)

 

[Narcogen]

Your GPU still needs to render frames before they can be encoded.

Any GPU can be overloaded.

Having game and display captures together can negatively impact performance.

OBS has to share GPU resources with whatever other apps are running.

I can't tell you why OBS can't get access to GPU resources to render frames, but I can tell from the log that it is happening, 10% of the time.

I followed this video and now it seems to work. I still get the fps drop sometimes. https://www.youtube.com/watch?v=fPhDIyehQBI&t=365s
