Since when is performance no-longer enough ? Is the smoothness really that big of a difference ? I bet a crappy display or cheapo HDMI cable could cause more "stutter".

Think of it as a deeper dive than the standard "frame per second" into "what's inside that second".

TR has published a lot of data and reasons behind their switch, worth the read if your a techie.

Isn't that the point of taking high speed video? You take it at high speed and then play it back slower so you can see what is happening faster than normal video can record. If you record it at 240 and played it back at 240, that wouldn't really show you much. Think about a high-speed video of a water drop hitting the ground - the high speed camera played back at normal speed lets you see things that you wouldn't see normally, because they happen between normal frames.

I can't tell much from that. It seems the AMD side is choppier at first and then after a bit they seem similar, or maybe my eyes adjust. This is all quite fascinating.

Too bad you will never notice that while actually playing as no one watches 240FPS slowed down to 30FPS.

That is an excellent point. I've got no idea, although my research indicates it is a video BIOS level setting that controls it. That would indicate that even ATI's "Never Settle" driver update can't change that particular part of the code, which is relevant as other tests have tried to answer the issue of "Which card is better?" using several ATI drivers.

It provides video confirmation of their results. Their findings are now incontrovertible. Whether or not you can perceive the stutter is another issue entirely.

i agree on this but the 660 was consistently choppy where the 7950 was fine for 5 seconds or so then dropped and continued
I should game.

I think that's their point, they are both a little bit choppy but the 7950 has larger spikes. The premise being that the little choppiness you see on the video is below your perception level, but that the big chops are noticeable. So all that little choppiness that both cards have is lost, but the big skips stand out. So if it was 5, 5, 6, 5, 5, 5, 5 you hardly notice the 6 because it doesn't stand out, but with 5, 5, 5, 20, 5, 5, 5 the 20 is very noticeable. I think that's what TR was trying to show, but the problem with the high speed video is that you can't tell what would be perceptible at 60 Hz when viewing it.

Lay off the drugs. The 7950 is very obviously dropping frames and has a far more uneven frame rate.
The AMD guys don't even have working eyeballs.
