I am experiencing stuttering while I am broadcasting.
To just test the problem, I created a local server with only me. I am just walking back and forth between one point that I experience the problem. When I am broadcasting, I feel the lag. When I am not, I do not feel the lag.

Here is a video of what I'm doing video.
My CPU usage does not get high and my FPS does not seem to drop (around 200+).

I ran my log through the analyzer and I didn't get anything.

OBS isn't particularly reporting any problems, so I'm not entirely sure. You might want to experiment with the settings and source types and see what really affects it (usually this is the capture types, output resolution, fps)

I really suggest capping your CS:GO framerate. OBS and your game have to use GPU time, so you have to give enough wiggle room for both to work.

If you absolutely must play CS:GO at extremely high framerates while streaming, you should look into getting a 2nd PC dedicated to encoding.
