Thanks for the help anyway! Keep working with DI, it's so much fun to use!

Nevermind I fixed it, all i had to do was not play as a administrator
sorry for the time waste

1920x1080 @ 60hz
Ps I use Alienware 15 R4 Gaming Desktop

I like to play in Full screen mode but every time I turn on full screen it doesn't work. I tried restarting the game, my device, even disabling and re-enabling DI but it won't work. Pls note that I am using the recommended textures for DI.
