Hi! I recently got my 2,4 ghz MPB (15 inch), and I installed Vista with Bootcamp 1.3. Now iTunes-Cover Flow runs fine under OSX, but under Windows Vista it is painfully slow. Maybe it's related to the adaptive GPU Speeds of the 8600GT, and iTunes can't make use of the full GPU Performance. I already updated to the newest WHQL Forceware drivers, but couldn't notice any improvement. Games run fine (very good in fact, Stalker and Call of Juarez with full details and highest resolution run perfectly smooth). Any help appreciated!
