A tremendous amount of data is created during the capture and analysis process including charts that plot out the 95th and 99th percentile frame rates as well as charts that show the observed FPS versus the FRAPS FPS. Below are some representations of the data presented showing that yes, even with the latest drivers AMD is struggling with some frame time issues that drive the FPS delivered down to a level below that reported by FRAPS. Looking at the Frame Time chart you can see that when run in a CrossfireX configuration the frame time data is all over the board whereas NVIDIA`s multi GPU solution delivers a consistent line across the chart. Slightly wider than the single GPU line but still much improved over the AMD configurations. Another look using the percentile chart illustrates this a little differently, showing that as the outliers are removed the FPS takes a downward swing. The results from one game do not tell the whole tale so looking at BF3 as well as Far Cry 3 provides a pair of results to illustrate the point with a little larger base of video cards."
