I am finding FFXIV has the most issues out of any game I play with interacting with Video drivers. Even more so then other SE games. Things seem to break from patch to patch with no changes on my side. Personally I think the blame falls on a mix of the Video card manufactures and SE. IF it was 100% ATI then a patch would not break as many things as I've seen break (Crossfire, etc.) I think a lot of the issues are due to the fact this is a DX9 game. I hope that the DX11 update with 3.0 addresses some of them. Sadly it appears this game runs better on older video hardware.
