Angular shadows in the wrong places :( (Far Cry 3)

Good afternoon everyone!
During the game, I see strange shadows where they should not be.
Win 10 pro
Comp Asus x555ub Video nvidia geforce 940m, percent 2.6GHz
With the drivers, it seems like order, the computer does not overheat.
A hundred pluses in karma for someone who will tell you how to remove this glitch !!
Thank you!!

I am attaching a photo, for some reason I cannot screen it :(
