The switching between Desktops in Mission control via left right gesture or option arrows is really jerky on my 2010 MBP with Intel. It is everything but smooth and horribly slow. There seems also a huge different between content. If I switch to a big Chrome Window it is very jerky an empty Desktop is fairly smooth. Is there anyway to get the speedy animation of ctrl 1,2,3,.. for the left right switch? It is so annoying I might try to write a script that triggers the appropriate ctrl + number.
