One of the reasons I switched to XP after many years of flying FSwhatever is that the XP stock scenery is so much better. Much more detailed and accurate, and better textures. With XP I feel very little need for payware or even freeware add on scenery. I also find that XP performs better overall. Very smooth, no "stutters", even at large airports. FS9/FSX do a better job on ai traffic, though.
