Same thing, also black missing textures on the Ice cave map...
I didn't get the DirectX error until tonight, but have been dealing with the missing textures thing since beta 15.11.1. These issues didn't exist in 15.7.1
Either AMD or DICE will fix it. Don't let the fact that they won't acknowledge it on here fool you. They're both well aware of it. lots of folks have been complaining about the ice caves issue on the battlefront forums, reddit, and here. Folks have also put in tickets, error reports etc.
The directx error forced me to reboot. Radeon settings crashed when I tried to open it afterwards. After the reboot it worked. I was playing for about an hour before it happened.
