OK, open up your game folder and browse to \GameInfo\Gameplay.constants file. Open it in your handy-dandy favorite text editor and search for this line:
gameSpeedData-Fast
If you look at that section (and the -Normal and -Slow sections before it) you can see what variables are altered when you go from slow to fast. Here's the whole section...

Edits here will not adjust combat times, merely how fast things get done. I noticed (I think) that the ship speed adjustors helped not only regular flight, but hyperspace as well. I do need a little more testing there tho.
Can anyone tell what the culture variable does?
