Microstuttering tests on ATI Radeon HD 4870 X2

@SAMPSA:

No matter what you do, but when testing microstuttering (MS), you have to test at the same FPS LEVEL!! Best @ ~30fps. Adjust all settings so that all cards are @ ~30fps when you test MS.

There is NO sense in testing card A @ 30fps and card B @ 50fps only to find out that card B @ 50fps has less MS than card A.
Usually higher fps result in LESS MS, that is just my experience.

MS is most annoying when playing at ~30fps, because SLI and CF Setups are mostly there to make settings playable that were unplayable with just single gpus.

If you have MS @ 50fps, who cares? Because 50fps WITH MS still feels very playable, similar to 35fps with a single card. But when you get MS @ 30fps, it feels like 20fps- and THAT'S WHERE IT HURTS.

So PLEASE test all single and multi gpu setups @ 30fps- only then can we can find out whether CF really shows better MS handling than SLI or not.
