I was able to finally get ME2 running smoothly on OSX via crossover. The graphics and frame rate seems smooth; however the graphics are much better in native windows. The game his very playable with some issues with the mouse sometimes not giving you a full 360 degree turning radius; however it eventually lets you turn fully around. Playing in OSX helps out by freeing extra space on my bootcamp partition, especially since drive space is somewhat limited on the 11" I am impressed with this system!
