My 2-cents...
Same basic setup as Fastcargo's (Vista32, SF2x, cept a 3.0ghz proc) and the FPS has doubled. Cool.
Oh, here's something I've done with the noise texture. Haven't dug into the archieves far so this may have already been done/mentioned....
Increases the frequency of the noise texture.
in <Theatre>_DATA.INI
-----------------------------------------
[NoiseTexture]
Size=256
MinColor=229
MaxColor=255
// oem:Frequency=1.7
Frequency=4.0
// oem: ResolutionFactor=4.0
ResolutionFactor=16.0
// oem: 200
StartFadeDistance=500.0
// oem:500
EndFadeDistance=1500.0

Gives, to me, more of a sense of speed at low altitude. On my rig no slow down noticed (shouldn't be on a good V.card). The "oem..." above means the original values btw. You may have to play with the filtering and mip-mapping in the v.card setup. Also, haven't had time to play with the values much (working on a Campaign viewer/editor) but the "ResolutionFactor" seems to be the biggy.
No pix but a still shot doesn't do much for ya - need to be moving...
