6870 vs 560 good read

This was very informative, thanks for posting. This is eye-opening and depressing at the same time, because while nVidia seems to do a better job than AMD at microstutter, both are far from perfect as the results show. It also seems to be dependent on games, which means you might be out of luck if the driver team abandons older games or low-profile new games.

Either way, thanks again, it'll be something to look out for with newer driver updates.
 
Most cases that I've seen AMD cards deliver better average frame times than Nvidia ones in Scott's testing.
 
Wheres the argument for the claim that frame-latency-matters?

Doesn't triple-buffering and/or the DVI/VGA/DP specs force mux/demux at an exact frequency anyways?

Theres no real analysis or hypthosis put forward, just "I don't like average framerates, so heres another metric".

The good thing about this analysis is it quantifies, or makes objective, the improved game play experience. Sometimes I see reviews discuss the fact that one video card is "smoother" or "feels more playable", subjective statements that will not hold true for all gamers.

Also, the more video card reviews that incorporate this type of analysis, the more Nvidia and AMD will feel compelled to improve the gamer experience. We gamers are looking at continuously improving the gameplay experience, not in winning benchmark comparisons (the latter is only useful for fanboys).

somehow I managed to miss that, touche

still, a graph of fps over time is going to contain the same data as a graph of average frametime (because, literally they're the exact same data, one just has y inverted). This is data [H] has been recording for a long time now.

Did you even read the article? Look at the Witcher 2 results

The problem with FPS over time is that FPS only looks at one second at a time.. if a game is running at 60 fps, that means it is taking 60 points of data, and averaging them out over a second. That doesn't sound like much, but in the 'feel' of a game, one second is a very long time. This method looks at every single frame that is passed through the renderer, and times them. That's why Witcher 2 can run at around the same average FPS on both cards, but suck hard on one of them. Some frames are being delivered at <10 "fps" while others are dropped completely to keep up. That's why you get micro stuttering. And the problem is even more severe with SLI
 
That was a pretty amazing read, and I really hope Kyle and Brent take notice and at least partially incorporate it. It helps explain their recent subjective preference for Nvidia card smoothness in the last few reviews.

Thank you for that explanation, I read the article but interpreted it different, with this it makes sense now.
