Kingdom Hearts: Birth by Sleep - US - ULUS10505

[Mavius]

excuse me, but i can play FF 7 crisis core on my computer, but i cant play birth by sleeps because of low FPs. what is diffierence between two game?

I don't have that game to test it but so I don't know, for the low fps, check the configuration I wrote in the other post and then post if it works for you.
If that doesn't work then it's probable that your computer can't handle the games.
