Hp Reverb G2 feels "stuttery" with 30 FPS Settings?

In a sense yes, as is shown by the noticeable stutter in panning shots of 24 fps movies. It’s more noticeable in some scenes than in others.

It’s not really a fair comparison though. One is a cinematic experience in 2D that we have been used to for decades, the other is a simulation of reality in 3D. 30fps can be fine in 2D games (though 60 is vastly better), but not in VR.

VR requires more FPS than 2D for an acceptable experience. Why do you think 72hz/fps+ is the standard in VR? The only reason people settle for less is because they are forced to by hardware constraints. In movies, people are so used to 24 fps that more looks weird, as was the case in the Hobbit movie (60fps).
