This has probably been posted and/or discussed somewhere already but look at these recommended specs. Before looking though, my general rule of thumb regarding specs is that if you want to run the game at highest level you generally need a fair amount of horsepower beyond even the recommended specs. I have posted Square's *recommended specs* below:
OS Windows® 7 64 bit
CPU Intel® Core™ i5
Available space on hard disk/SSD 20GB
Graphics Card NVIDIA® Geforce® GTX 5xx Series
Screen resolution 1920x1080
Connection type Fiber optic
Connection speed 100Mbps
Realistically I would say to run the game balls to the wall you want no less than 8 gb of ram (probably 16), the newest graphics card out there, and probably a fairly robust processor (moreso than the Core i5). But wait a minute, before you shoot me down here, take a look at one thing that really bothers me in the *recommended specs*. I have bolded it for you.
Does Square realize that Fiber Optic connection is still pretty sparse even in big cities in America? Is this going to make gameplay lag for those of us with a measely 50mb cable connection lol?
