August 28, 200817 yr Some users report that XP64 of Vista64 will lead to a "smoother" simulation experience, but there are no outright improvements to FPS or other details. If you move to XP64 of Vista64, expect to get perhaps more rapid flight load times (not by much) and perhaps faster/better "blurry" prevention, but no frames-per-second improvements.Report back if you make the switch!-Greg
