Question / Help When recording @ 30 FPS, if game play is not 60 FPS or 30 FPS, video is choppy?

People have been complaining that my video streams are a bit choppy. After doing a bit of settings tweaks, I found that unless I'm getting 60 FPS or 30 FPS on a 30 FPS stream, the video playback is significantly more choppy than what's displaying on my end. Capping in game frame rates to 30 FPS largely alleviates the issue. However, not all of my games run at 60 FPS. This occurs with game capture, window capture, and even monitor capture. Is there any way to alleviate the issue without capping the in game frame rate?

Here's a video demonstrating the issue.

Any ideas?

It's possible that if the game is running at a really high framerate that the game is eating up a lot of GPU and causing issues with OBS' rendering pipeline. Sometimes capping the game at 60 actually helps even out the GPU usage between the game and OBS in certain cases. Not entirely sure though, just guessing at this point.

Good call on the GPU usage. Before, Borderlands 2 was configured to make full use of my GPU, stressing it enough to have the frame rate dip below 60 (obviously). After disabling a few graphics tweaks to reduce the GPU workload, the frame rate on the output stream appears fine. Initially I thought the video playback was appearing choppy because the in game frame rate was not a multiple of 30 when dropping below 60 FPS. However, capping the in game frame rate to 45 FPS after disabling said graphics tweaks yielded an output that was equally smooth as when the game was capped to 30 FPS.

Thanks for speculating. I would have never suspected the culprit was the GPU usage.
