I tired looking through AMD's CCC to see if I could see something but couldn't. It happens on the TV too (I use it as a second monitor).
Your right, moving around windows does use CPU, just tried it on my other PC, I guess that's not a problem then but thought it might have something to do with the tearing.
ISP won't do anything because I do get full speeds on wireless so it's not a problem at their end. Obvious thing I haven't tried yet is a new cable. If that doesn't work I'm just going to go wireless.
So I guess the tearing is the main issue that needs resolving.
