According to Rockstar Games, Grand Theft Auto V is their biggest and most ambitious project they have ever created that will take advantage of the current-generation of console’s processing power. That being said, there will be compromises that needs to be done in order to deliver the best performance in both consoles.
Regardless of what versions you will be getting this September, both the Xbox 360 and PlayStation 3 will have a mandatory 8GB of install. Those who will pick up the Xbox 360 version, expect a two-disc set where the first disc will install the 8GB of data while the other is the one you need to put in to play. As for the PlayStation 3, it will only come with one disc but as soon you put that disc on your PlayStation 3, prepare to download the hefty 8GB of data as well.
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.
In addition to the mandatory install news, Rockstar Games also plans to release its first gameplay video really soon.
