Final Fantasy XIII runs flawlessly for the most part. I would have said flawlessly, but one part of one area I experienced frame drops down into the teens. Once I made it past that area though I had no problems. If you run into any more issues after following this guide please let us know.
I really enjoyed Final Fantasy XIII on the Deck. It’s one of those titles I’ve had in my library for a long time, but I had a hard time starting it. Playing it on the Deck fixed that problem, and I can’t get enough.
