Hi,Please forgive my dumbness, but what does SP2 do for FSX without having Acceleration installed?Jim

The exciting bit for Vista users with DX10 cards is DX10 support. Very pretty they say. There are some other fixes and implications:http://jonpatch.wordpress.com/2007/12/14/notes-on-fsx-sp2/Jon

DX10 under Vista 64 = 25 to 30 percent increas in FPS over DX9 on my box, all sliders equal... If you run vista, very nice.

Atleast that's my experience with Acceleration/SP2 on Vista vs SP1 on XP (Dual boot) on my system. Check out ResetMCP's benchmark thread in the Hardware forum!!
