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.

More coming soon, now I have to go and attend beachsoccer tournament!

maybe i missed something in the whole micro studdering debate but the 4870X2 @ 21.9 fps would have more microstuddering than the 3870X2 @ 49.5fps.

also how much of this studdering is caused simply by the fact that Xfire doesnt even work properly for that game and if it did work properly, it wouldnt happen ??

21.9fps would look like hell and be not exactly unplayable but would absolutely exibit jitteriness from the low framerate. not microstuddering but simple video lag from low FPS.

i think the microstuddering has been taken too far by people who don't understand the difference between microstuddering and just plain 'ol low fps lag or skipping.

i personally have never seena game do this so i can not speak from experience although i do understand what microstuddering means.

i may in fact, now that i think of it, have seen microstuddering with my 8800 GTX when running a too high of overclock.. the overclock doesnt fail persay, the frame rates are way high. (60fps or higher) but the game or benchmark is jumpy... run. skip run skip all within a seconds time...
once you downclock the gpu or ram (mostly gpu) the skipping/studdering goes away.

is this similar to what you guys are coining as "micro-studdering"?

has anyone SERIOUSLY sat down and played with various variations of gpu to mem speeds in terms of overclocking, even underclocking, to see if it goes away?

it may not make any difference since each card handles 1/2 the work load, but its just a thought.
