Textures Broken on Forza Motorsport 6: Apex

Hi all,
I’m having this problem on my computer. I really need some help, if any of you out there know how to fix it, or have any suggestions, it would be greatly appreciated, I really want to play this game.
PC is Dell Inspiron 13 7359, with Intel i7-6500U, 8GB of RAM and Intel HD 520 integrated graphics. Its not great but everything else runs smoothly.


Thanks.
