Microstuttering is a defect in image quality, where small pauses appear, creating less smooth movement in games. The effect is shown in
this short article from Extremetech.
Microstuttering has plagued SLI and Crossfire setups for a very long time now. Nvidia has spent much effort in reducing this by introducing hardware based frame metering with Keplar.
A new review from Toms Hardware regarding AMD's 7990 and Nvidia's 690 had some really interesting results in their tests. It seems that when they apply Dynamic V-sync control with the third party app RadeonPro, microstuttering is reduced to almost nothing. The graphs shows that crossfire are even smoother then single card solutions with DVC applied.
From the review:
Quote:
Aside from a few dropped frames and a handful of spikes when the test changes scenes, our dual-Tahiti card enjoys much smoother sailing. In fact, the end result is often better than what you'd see from a single graphics card, with virtually no micro-stuttering left.
