Good news! I can confirm that based on my own tests microstuttering is gone on R700!
I've tested with R700 (ATI Radeon HD 4870 X2) and R680 (ATI Radeon HD 3870 X2) in Crysis (1600x1200 and High settings). I used Fraps and enabled Frametimes logging. I recorded 2 seconds from exactly the same point in game (loaded from save game). Based on my recorded data, with ATI Radeon HD 3870 X2 frames are rendered after ~21,5 and every other frame after ~49,5 ms. With ATI Radeon HD 4870 X2 all framres are rendered after ~ 21,9 ms.

here's the card he's talking about.
It's not FPS, its ms. Explanation (1s=1000ms):
Quote:
21.9ms doesn't mean 21.9FPS. It means 1000/21.9 = 46 FPS.
Every odd frame at 20ms and every even frame at 50ms puts the FRAPS framerate at 1000/35 = 28.5FPS; and puts the actual fluidity around 1000/50 = 20 FPS
Every frame at 20ms puts both the FRAPS framerate and the "real" framerate at 1000/20 = 50FPS. Believe it or not, the fluidity of 4870x2 in that certain scene is 2.5 times better than 3870x2
