Oh man, this one drove me absolutely crazy during my playthrough. Too bad the game itself did so even worse and kept me from continuing the other parts.

Wow, I just began playing FFXIII 2 days ago, could it be the same day the rolled the fix? I remember reading it needed all kind of fixes to run, even a third party mod, but other people commenting it ran out of the box for them, as always, nothing for sure, but because it was so cheap and it's such an iconic game for me, and yes, it's really really good, both the story and the gameplay, the later after 2-3 hours into the game.

"Need" is a strong word in this case, 13 does run out of the box but FF13Fix does alot to make the game's frame pacing and UI elements bearable as the port is pretty abysmal. I would consider it essential on PC even though it technically works without it.
