DirectX error message, can't get into a game,

Same here... it's a Known issue, I think. They need to release another patch. Problems started with last update. Before I was playing without problems on Nvidia 1080 TI Waterforce - i7-8700k and last driver update. The single player campaign works fine.

Thanks for commenting.  I'd buy a whole new PC if that's what it takes, but considering that the game played fine for ~three days I don't think that's needed.

That did it!  My sincere thanks.  It's strange, though, that it played fine for about three days with the graphics on default settings.  "Oh well."

Same.  Only since the new update.  Game crashes, DirectX issues, etc.  Hopefully, they patch it again soon.

MainframeTV's suggestion, lowering Mesh Quality to Low, worked for me.  Best of luck to you.

This is not the solution. This is a duplicate of DXGI_ERROR_DEVICE_REMOVED or DXGI_ERROR_DEVICE_HUNG | EA Forums - 12737991 which has been acknowledged as not resolved. Modifying game settings like lowering mesh quality only helps some people and only temporarily, a proper fix is still not available, I can't play Multiplayer no matter what I do.

Yeah, that was strange. Also for me the same problem. I think that some bug occured during update in Mesh settings 

I'm sorry to hear that you can't play Multiplayer.  Don't give up.  I've been playing Battlefield for twenty-three years and these things always get resolved, one way or another.  With one Battlefield game, I don't remember which one, I had to buy and install a new graphics-card.
