I played ffxiv fine yesterday, but today, both times I have gotten on I had terrible artifacting. None of my other 20+ games artifact at all, just final fantasy. My GPU is not overheating, and it isn't overclocked. I noticed that the game was set to full screen, but was in a window, so I changed it to borderless window, and it still happened.

Going to try reinstalling the video card drivers, but other than that, i'm out of ideas.
