Yeah, but Motion Blur looks good
Well actually, it depends what type is used, because they could simply use an image motion blur which is computed rather than actually happening by repeating polygons which is the best way to do it, and most clear.
You can't forget all the advanced effects were going to see in next gen games though like camera focusing, and all those lovely 48x pixel shader pipelines being used
Haha and I just had a thought.
If they contain motion blur which makes 30fps look like 60.
Simply turn Motion Blur off, and you get thetrue 60fps
