Just got my new MBA (the standard 13'' version). All was well until I installed Civ IV from Steam. I've already been running it without problems on my iMac (2009). But on the MBA: first, under its standard settings (graphics: low) as it started up, all the trees on the map were flickering. That seemed odd, so I thought let's play a bit with the graphics settings. I set the graphics to high terrain and medium rendering; it then asked me to restart, and now it's totally bu**ered! Regardless whether I try to load a saved game or start a new one, at the point where it's supposed to start and show the map, it freezes; the sound goes on in the background, but the map never shows. Since I can't get into the game proper anymore, I can't get back to the options screen to try and undo the graphics settings. Not cool. Anyone else experience any problems with Civ IV on the MBA? I guess I'll have to uninstall it and reinstall from Steam. But then again, the flickering trees at the start weren't too great to start with. Surely that's not the best the MBA can do with such an old game? Is there something wrong with mine? Or maybe a Lion issue? If my 2009 iMac runs Civ IV without trouble, surely the MBA should?
