I have an AMD r390x 8gb on an alienware 15 r2, and I keep getting screen tearing when I look left and right. This seems to be an in-game problem. Does anyone know the best settings for AMD's Radeon Settings? Can you please share them? Also, this is on a 4k screen, 6820hk CPU, and 32gb ram laptop.
There are no 'one size fits all' recommendations for optimizing any game.
You should post this query on the Overwatch forums.
