However in this example we have a 1:1 screenshot with ATI on the left and to the right NVIDIA, we nowzoom in at the terrain. You'll agree with me that if you look at the background closely, you'll notice that that surface area is a little sharper for NVIDIA. ATI does have a little more work and polishing to do. Object quality definitely is the very same.
