FFXIV is DX 9.0c...
Your point? It supports DX11 features, just not optimized, however if you didn't hear, MS is trying to get people off of XP and Vista. To get DX11 you need a DX11 card as well as Windows Vista/7/8.
Maybe a hacked DX11 for XP..Idk though. Edited, Jul 20th 2012 10:01am by Theonehio
