See FFXIV: A Realm Reborn's Graphics on PS3 and PC
Final Fantasy XIV: A Realm Reborn's new Eorzea touring trailer includes both PS3 and PC footage, and it gives you a view on how the world looks like in the game's PS3 and PC version. If you feel the PC footage looks more beautiful than the PS3 footage, your feeling is right. The game's Producer Naoki Yoshida has told in last year that the PS3's graphics settings are equivalent to PC's medium settings. In other words, if you want the best FFXIV graphics, you should check out the PC version.
A Realm Reborn will kick off the next round of closed beta for PC next month, and it will also start testing the PS3 version at the same time. The release date, according to Square Enix, it will be August 27, 2013. You can learn more about the pricing here.
