All of Universal's ride media that I know of(Spidey, Transformers, Despicable Me, Simpsons, to name a few) displays at 60FPS, which is considered to be a high frame rate (film in theaters is 24FPS and most televisions display at 30). FJ also displays at 60, and I'll assume Gringotts does as well. Do other attractions bother you in the same way, or just FJ? As someone who enjoys video games, I engage with 60FPS images quite often and love the smoothness and clarity of motion that a higher frame rate offers. 30FPS looks choppy to me at this point lol.
