Is DX11 Client going to be separate?

[Nihility]

They have explicitly stated that the DX11 client will be an entirely separate download a few times, so unless stated otherwise more recently I would assume you have to download the new client.

while i don't doubt you that it was said, a dx11 "client" should just be a small-ish file that contains settings for windows to use dx11 with the game client.
It honestly should be so small that it would be included in all windows versions of the game need it or not

An entirely separate game client to use it doesn't even make sense.
