Polyphony Digital’s gigantic racing sim Gran Turismo 7 will ship on two Blu-ray discs on the PlayStation 4, but will only require a single disc on the PS5. Confirmation comes by way of Sony’s own online storefront PlayStation Direct, as spotted by GT Planet, which states “2 Discs” will be required for the physical PS4 version of the game. This information is absent from the PS5 listing.
Presumably, this all comes down to the maximum capacity of the storage medium. The PS4 has a standard Blu-ray disc drive, which can handle around 50GB on a standard dual-layer disc. Meanwhile, the PS5 is equipped with an Ultra HD Blu-ray disc drive, which can support up to 100GB on a triple-layer disc. The small-print mentions that you’ll need at least 110GB reserved for Gran Turismo 7.
It’s not exactly surprising, as the re-released GT Sport Spec II also shipped on two discs physically for the PS4, and included every update added to the game as of v1.39. Prior to that, Gran Turismo 2 on the PS1 launched with two discs, including the entire Arcade Mode on one CD-ROM and the complete GT Mode on the other.
