im not sure what was involved in this latest upgrade but the performance of the card in my mac (nvidia card) is about 100% better than it was before.  far less stale shares and the performance chart is not bouncing around anymore.

before the upgrade the performance chart for that card was bouncing from 0 to 50mh now its far more consistent and climbing since the upgrade and hovering around 75mh.  

i dont really know if it is an actual improvement or not but it sure looks much more stable.  i have not noticed much change at all with my main mining rig.. that is still chugging away at around 1200mh.

nice work on the upgrade.  unreal change for my mac and crappy nvidia card.
