ITs in the middle and in the corners. There is also something in the left bottom corner. How do I turn it off and why is it even a thing?
it's was a NDA "security", you can't turn it off. if you stream or published videos, with this Ubi can find you and ban you...
As sa0n said, it's so they can see who leaked video or photos of the game. The watermark is there to protect you as much as it is to protect Ubisoft.
