Day before yesterday: A few crashes happen, but when I turn off my pc for the night it says that it's gonna do a few automatic upgrades. Neat, I think, and let those upgrades happen. I don't touch any of my pc or game settings, just let the updates do their things.
Yesterday: FF14 plays flawlessly, with zero crashes. Is this it? Did my fatal directx errors finally go away thanks to those upgrades?
Today: Game crashes after 15 mins of playtime. So the issue persist.

What in the seven hells am I supposed to do?!
