I fixed it! I found these instructions for the sound loop error, but it worked for the direct x error. I had this error every single time I played, but now was able to play all night. I'm not sure exactly what this does, but at least I have it working for now. Give it a try, and if it still doesn't work you can always just delete the user.cfg file.
Create a user.cfg and place in BF4 directory and copy paste the text below.
RenderDevice.Dx11Enable 1
RenderDevice.Dx11Dot1Enable 1
RenderDevice.Dx11Dot1RuntimeEnable 1

gauntlet0 - You rock! This fixed the DirectX error for me as well. I wasn't able to load any part of the game at all since launch until I created the user.cfg and added those settings tonight. Thanks!
