The only thing I can say is the it will probably run better than most people tell you. Most people like to say how insanely hard it is to run the witcher 2 maxed out so witcher 3 will also be so hard. Well actually the witcher 2 was one of the easiest games to run, even for it's time. You just don't turn on ubersampling and you will be fine. Might as well just be 4k supersampling. So I get the feeling that it will run quite well on 970m.
