My be an issue with Optimus not picking up the DX11 executable. Might need to add the DX11 client to the list for 3D games. There are now two ffxiv executables--the old DX9 one (ffxiv.exe) and then ffxiv_dx11.exe. They are both located in the "C:\Program Files (x86)\SquareEnix\FINAL FANTASY XIV - A Realm Reborn\game" folder by default.
