The PlayStation 4 Pro is, as we're sure you know by now, a more powerful PS4 capable of all sorts of extra performance and graphical improvements. Though, for the case of Mass Effect: Andromeda, it looks like a higher frame-rate than 30 frames per second won't become reality.
The game will run at 30 FPS on both PlayStation 4 and Playstation 4 Pro. This was confirmed by producer Fabrice Condominas in an interview with Gamespot.
This won't come as a shock to anyone that's played Bioware games on console before and the extra GPU juice of the Pro will obviously be used to beef up other areas of the game's visuals.
