They showed games there as well apparently, should be some footage soon. Although you're watching it through a camera that can't record it properly and a monitor that doesn't display its effects correctly. It will be one of those things you need to test yourself, peoples perceptions of input lag and frame rate vary wildly, it's also down to what you've become accustomed to.
Ryan said Pcper are doing a hands on demo with it on Monday.
The part that struck me was, Linus was chatting for a couple of hours after the show to various people and went over that demo of the pendulum again. It was spinning around with the pendulum going back and forth and he showed frames as low as 30 in places and commented on how smooth it was dropping from 60 to 30. No way you can see that with a camera recording but something I would like to see running on a G-Synced screen.
No more will people need to buy the top card to get ultra settings @ over a constant 60fps. If it does make 30 fps as smooth as >60, I can see this being a massive hit.
