Here are all details about whether or not any special install requirements is needed for GTA V on PS3 and Xbox 360.
Grand Theft Auto V is the largest and most ambitious game we have yet created, and takes full advantage of every ounce of processing power available in the current generation of consoles.
In order to provide the best possible experience for such a massive and detailed world, the game will have installation requirements on both Xbox 360 and PlayStation 3 systems.
For Xbox 360, Grand Theft Auto V will ship on two discs; Disc 1 will be used for a one-time mandatory install and Disc 2 will be used to play the game. After the install, players will be able to enjoy both Grand Theft Auto V and Grand Theft Auto Online without any need to switch discs.
This initial install will require an Xbox 360 Hard Drive or an external 16GB USB flash drive with at least 8 GB of free space. If using a USB flash drive it must be at least USB 2.0 with a minimum 15mb/s read speed and formatted for Xbox 360 use. A new USB flash drive is recommended to ensure optimum performance.
For PlayStation®3, the game ships on one disc and will install content as soon as you insert the game. The install is roughly 8GB, and players will be able to play as soon as the install is complete.
I have the Xbox 360 4GB or Xbox 360 Arcade/Core system so I don’t have 8GB free. Can I play Grand Theft Auto V on Xbox 360 by installing to a hard drive or USB flash drive?
You can install Grand Theft Auto V to an Xbox 360 hard drive or USB flash drive (sold separately) on Xbox 360
