On PlayStation 4, Hogwarts Legacy runs in 1600x900p at 30FPS (30FPS to 50FPS with unlocked framerate), whereas the PS4 Pro manages to run the game in 1080p at 30FPS (30 to 60FPS with unlocked framerates). While the PS4 and PS4 Pro versions suffer several downgrades, including lower drawing distance, lighting, and removed assets, the game remains to look impressive on Sony's consoles. In addition, it's impressive that the PS4 version manages to run at framerates up to 50FPS. Loading times might be the biggest issue on both PS4 and PS4 Pro, being roughly 8 times slower compared to the PS5 version.
