Hi there! I've bought an Air, which I'm really happy with it so far. I've created a Windows XP partition (Boot Camp), updated Windows, DirectX and the graphics driver too. I've decided to install a few old games. Then, I've turned off paging (in Windows virtual memory settings) and defragmented the drive. I've disabled any known power saving feature (on the graphics chipset and Windows itself). All the games, even those 7 years old (like Return to Castle Wolfenstein) are running fine for the first minute or so then start stuttering badly. When the game is launched, gameplay is smooth, which indicates that the X3100 can handle it (at least for a given amount of time). Stuttering occurs suddenly, for a few seconds and re-occur every 30 seconds - 1 minute or so. That's really annoying. Sometimes, when stutter is really bad, audio stutters as well. I've tried a few Intel native games under OS X. Although I'm getting bad framerates in some of them, it's more or less constant and there's no or verry little stuttering. I'm a bit despered. I mean, from a raw power perspective, the X3100 should be able to handle any pre 2003 game. And, the spontaneous stuttering (occurring every 30 seconds or so) is an indication of a "generic" issue. Any idea how to improve this? That would be greatly appreciated! Thanks!
