I don't know what you mean 'playable' in high setting on your MBA. but I highly doubt that you can actually play without hip cop or slow motion. graphic card used on MBA is not sufficient for playing crisis 2. to me, 'playable' means that FPS should be more than 30fps. but I don't think that your MBA can do that. I guess 5-10fps? (high setting). that's not playable. I don't understand why people, who bought MBA, try to play games. if you wan to play games, you waste money to have mac. I have macbook pro 15inch. but I already know gaming performance is not greater than I expect. so I usually play it on PC. less spending money, and get maximum performance. how efficient.
