I only have thing to say, you can do anything right.
Fullscreen continues the exactly same ...., it doesn't work. ONLY GAME I OWE THAT CANT GO INTO FULLSCREEN, THIS SPEAKS FOR IT SELF.
And for what have been reading with your fix you only made thing worst for some players.

When you think ubisoft cant go downer than what they already are, they show you the opposite.

Congratulation, im impressed
