What's wrong with the graphics?

At the main menu does it show a HD Texture Download remaining? Top left corner. I had to exit the game, right click it in Origin Launcher and click repair or update (I think I clicked Update). It finished the download for me and it fixed my graphic issues. 

Also some have said the game is using your integrated graphics and not your GPU. You'll need to force it in the Nvidia Control Panel (if you use Nvidia)
