I was a reluctant to update with so many negative post but glad I did now. I noticed a little slowness the first time open BaseCamp but not it seems faster and I have not changed the screen resolution on my mac. I have a Fussion Drive on my iMac and SSD on my MacBook which may be helping but it also may be the Dish Cashe Size and 64 bit that is giving slightly faster redraws after updating.
