I don't see that a 960 is equal to a 780 anywhere on that chart. Knowing that a 780 is between a 770 and a 780Ti, that puts it far ahead of the 960.
Quitting for the night. I am very satisfied with the game. It is well optimized, and haven't encountered any bugs. I love being able to go anywhere.
Seeing as I've not even finished taking side quests in and around the first town for 4 hours, and knowing how large this world is, I see this literally taking a couple hundred hours, since I like to suck the marrow out of the story.
I have found the menu/UI to be much changed from The Witcher 2. I haven't decided if that is a good or bad thing yet.
As I said earlier, I chose high settings for my 780, as well as setting it to 60 fps in the menu. I turned motion blur off, since it bugs the hell out of me and looks unrealistic. I also set Shadows to medium, which hasn't hurt immersion at all. I see no reason to try Uber setting, since High looks so damned good and plays beautifully.
