I am not impressed when someone writes that simulation gets a higher frequency with the move from 30fps to 60fps, as almost all modern racing games should have this decoupled from the framerate anyway. If that isn't the case for F1, then that's an issue with the game right there.
I speak only about framerate. In racing games a locked framerate is very important for me. I have a PS4 and I hope Polyphony Digitial will do again a GT games at 60 fps locked.
