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?
