I hope its like this:No confirmation yet, but I can guarantee that there will be a 60 FPS mode. Sony hasn't released a single PS5 game with only a 30 FPS mode so far. Besides, this is a cross-generation game. PS4 will be at 30 FPS. PS5 will surely have a 60 FPS mode, minus 4K and ray tracing.
PS4 version (same as HZD):
PS4 - native 1080p @ 30 Hz
PS4 Pro - checkerboard 4K @ 30
PS5 resolution - native 4K @ 30
PS5 performance - checkerboard 4K @ 60
