Dissidia Final Fantasy Lag?

I have gen d 3 and well i want to download it but does it lag because most big games lag like VCS FFCC and ect ect.

I havn't exprianced any lag, buti have it in ISO format, rather than CSO.You could try downloading it as CSO, but if it does lag, and you have enough memory, i would suggest extracting it into an ISO.
