Hi, I am looking for some advice about Microsoft's flight simulators. I have a new 24 in iMac with 2.4 core 2 duo/ radeon hd 2600 256mb/ 3gb ram. I would like to use bootcamp to be able to play MS Flight Simulator. I'd like to either: 1. Install XP Pro and play MS Flight Simulator (9) 2004 A Century of Flight 2. Install XP Pro and play MS Flight Simulator X (2006) 3. Install Vista Ultimate and Play MS Flight Simulator 9 4. Install Vista Ultimate and Play MS Flight Simulator X The Cost of Vista vs. XP pro does not matter for me, I receive both at the same discount from a campus retailer. Also I understand many of you would recommend X-Plane over MS Flight Simulator, and I completely understand why. But I already have a copy of X-Plane 8, and I just prefer MS Flight Simulators. So what I am wondering is which of the above configurations would give me the best experience? I am worried that Vista Ultimate and Flight Simulator X might be to much of a graphics draw, and I would have a better experience playing MS FS 2004 with graphics at full settings, then MS X at half settings. Also the reason I would want Vista and the FS X is because of the Directx 10 support in Vista. However I heard that Vista vs XP will usually knock your frame rates down by about 10 per sec for almost every game. Anyway anyone who has experience with any of these configurations on a similar spec'd Mac I would appreciate any information or advice you could give me. Thanks! I didn't see this thread before posting: http://forums.macrumors.com/showthread.php?t=399550 Sorry to bring up a very similar issue discussed there, but if anyone has any feedback about some of other configurations I am thinking about running I would really appreciate it! Thanks!
