With the new PlayStation 4 Pro released worldwide, where the games can now be played in up to 4K resolution, Project DIVA X and VR Future Live will release a PS4 Pro update to increase video qualities. For DIVA X, game and Photo Studio graphics now supports 4K, 3D models become more enhanced, and VR mode for both X and Future Live now as smooth as 90fps. They still haven't mentioned about Project DIVA Future Tone, though. And we still haven't sure if 4K resolution for the main gameplay will limit frame rate to 30fps, like in other games. But if done right and not stutter, it might be one of the first PS4 Pro games to support 4K60fps, but who knows? The update will be released soon. http://info.miku.sega.jp/11505
Pro looks better, see for yourself. I mean, that's expected, see below for the actual difference. The standard (non-pro) version already had 60 fps.
