+1 to this, stock install had serious framerate issues and would frequently stop rendering at random intervals so you'd just be stuck with a white screen. i had to get a third-party mod and tweak a bunch of settings for the game to be playable on my GTX970 (and while it is an amazing game, it's certainly not a visual powerhouse that should tax a 970). works fine now fortunately, no thanks to square-enix.
