Hi everyone,

I've recently started using OBS to save small clips. I had originally used Nvidia Share, but it had some issues with clips from BF1 freezing. Anyways, now I've noticed that OBS has some issues recording from NBA 2K17. The videos turn out kind of jittery, but the strange thing is that it seems to only jitter when I'm playing an actual game. Here are some example clips so you can see what I mean:

https://streamable.com/f9lz (game, recorded using Nvidia Share)
https://streamable.com/087x (team practice, recorded using OBS)
https://streamable.com/g8ih (game, recorded using OBS)
https://streamable.com/8a4x (Battlefield 1, recorded using OBS)

As you should be able to see, the 3rd clip is jittery while the others are relatively smooth.

Here is the log from my last session:
