“The remaster for the PS5 is no simple up-res, as many of the game’s art assets have been completely updated to take advantage of the PS5 console’s horsepower. You’ll see better-looking characters with improved skin, eyes, hair, and facial animation (including our new, next-generation Peter Parker). You’ll also see ray-traced reflections and ambient shadows, improved lighting, more pedestrians and vehicles stretching further into the distance, and the same optional performance mode offered on Marvel’s Spider-Man: Miles Morales, allowing you to finally play the game at a targeted 60fps frame rate. We’ll be supporting near-instant loading, 3D audio, and the DualSense controller’s haptic feedback. Lastly we’re adding three amazing new Spider-Man suits, new photo mode features, and even new trophies for those of you looking to Platinum the game all over again.”
