So I had this problem for like a month now when im streaming Rust. I usually get around 120fps when playing and the same when streaming, But I still feel that I am lagging. My obs preview is set to 60fps and the output to Twitch too. The preview feels more smooth than the actuall gameplay. The framerate does say the same, around 120fps and still isnt smoother than the preview who has 60fps. Why does this happen?
