Unity Enable Directx 11 problem

when i go into the setting of the game i enable directx 11 and it tells me to restart unity, then i restart it but when i do this and go back to the setting it still says to restart unity to use directx 11. How can i get this to work?

You need to post your computer specs. If you don’t have a DX11 Compatible GPU, there’s your problem. Some cards support DX 9, DX 10, some 11. Post your specs. If you don’t have a DX 11 card, you need to get one in order to use DX 11. You must also be running Windows 7 to use DX 11. Really, the easiest way to see what version of DX you have:

Start / Run / dxdiag

When you open dxdiag you should see on the bottom of the first page: “DirectX Version”.

I found the answer for the problem, is not the DirectX, is the normal map, you must make sure the normal map is in 8 bits not 16 bits, if its 16 bits it will turn pink and will not render properly, also make sure you don’t have any alpha in the normal.
