Have no idea if it was stated ages ago or not but I am going to assume that they will have both based on that the benchmark offers both option.

I am asking because it seems to me that a few friends and I have "better" performance with the Dx9 Client rather than the Dx11 client. Score difference varying between 1000pts - 2000pts higher or 10-20 fps higher when it comes to dx9 vs dx11. While some claim that the dx11 client looks "better" than the dx9, I did not see anything different at all when comparing the two thus found it still worth using dx9 client. So just wondering if the Heavensward will make us use dx11 or if there is an option to continue to use the dx9 client
