Unable to use graphics card with DX11

[ViviN]

I've been playing with DX9 since Heavensward launched although my graphics card has DX11 support. I'm playing on a laptop so have the integrated graphics card and then have a GeForce GTX 860M as a render-only device. With DX9 the 860M is my only display option in game settings, but with DX11 it's only letting me select my integrated card which obviously isn't up to the job. Any ideas why I'd be unable to select the 860M when changing?

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.

Yeah that's fixed it, don't know how I didn't think of it as had to add something else to it a few weeks ago. Thanks for the help!
