Well it looks like the GTX 295 still experiences Micro Stutter.
I will be passing on this and enjoying my game experience with a single card still.
Oh God this sounds just like my 9800GX2 experience as well...
"In addition to this observation there is a input lag which is also connected to the function of the Alternate Frame Renderings (AFR). Dual GPU cards calculate a frame in advance (before it is displayed). Therefore the input lag becomes more annoying (like micro stuttering) if the frame rate drops. Quite logical actually, since at 30 fps a (lost) frame is more important than at 60 fps. This problem also depends on one's own preferences. "
