Never heard of the term z-fighting before, but it makes sense. Would this be an error in the games coding (Bug?) or is it more related to the drivers?
Some games do it (Not many) while in crossfire, whereas others don't do it at all.
Most games have it when viewing long distances. Like on bf4 and you be sniping from a far when you zoom in you see it.
It's not a driver or GPU issue it's the games engine. Only dice and reduce it.
