Sony has thrown the Day One patch of Gran Turismo 7 online and it is no less than 17GB in size.
The patch, which brings the game to version 1.05, has added several improvements to the game’s performance and the network. It also seems to prevent some crashes.
The game itself also needs 90GB of your SSD/hard drive, so keep in mind that you have enough free space. Gran Turismo 7 is available today for PlayStation 4 and 5.
