And here is gameplay footage of the exact same segment of Grand Theft Auto 5, but on the PC and rendered at 60 fps. The visual fidelity of the game doesn't change at all between the 2 versions. The threads of the baseball", so to speak, don't show up in either one, because that's not the point. The second video is animated much more fluidly and has a higher quality due to the higher framerate.
At the risk of sending this thread in an even less productive direction --nah, that's impossible-- are you sure the visual fidelity is the same? Looks different to me when paused. I find the framerate trivial compared to the other differences, particularly lighting.
Honestly, I'm not sure I'd even notice the framerate if I wasn't deliberately looking for it.
