This was with maxed out settings at 2560x1600 resolution, 4xAA, 16xAF, extreme tessellation etc, CPU at 4ghz, and 480s at 850/1700/4200..

The stutter index is high, but from what I could discern, the benchmark ran pretty smooth.
The tool is accurate - it just applies simple statistics to a FRAPS framelog. the exact procedure applied is given in the readme, IIRC.

The reason that it looked smooth is that your framerate is so high anyway. Check the apparent framerate - even taking microstutter into account, your "microstutter-free equivalent" framerate is 107fps. This should be pretty smooth. Like I said, the real-world effect of microstutter is to effectively reduce your framerate. If the framerate is sufficiently high, the game will still be smooth.


... But I have to ask - how in the hell are you getting those kinds of framerate at 2560, 4xAA, 16xAF?! Particularly with extreme tessellation. I get less than half that over the benchmark at 1920 resolution, and that seems to tie in with what others are getting...
