http://forum.square-enix.com/ffxiv/t...-DX11-Crashing
That thread for whatever reason they chose to move to resolved issues. This issue is not resolved i assure you. Some people had some luck with doing something with tessellation. But I tried all the tweaks, and still I crash nearly 50% the time I teleport anywhere, and 100% when I zone into a dungeon. I have to run in DX9 if I want to play at all. I wish we had some kind of official response this is being looked into because it is effecting both nvidia and AMD users alike.
