This is my hardware:

P iv 1.7 Ghz
512 Mb Ram
XP Home
GeForce 2 Mx 400 Graphics Card
NVidia  43.45 Drivers
Dx 8.1

I have just run 3DMark2001 SE bench mark tests and I hve scored a very poor 2630.  I need some help here to sort this baby out.  I don't know my Anti-aliasing from my Mipmaps.  If I could get some assistance I would be very, very grateful.

Here is what I did to fix some big problems with my MX 440, which I don't think is much better than the 400.  You might try to DL DX 9.0.  I was having major problems because I think one part of the computer thought I had 8.1 (which is what I thought I had at the time) and the DXdiag program listed me as 9.0.  FS 2002 Pro always switched to safe mode, saying I had no hardware acceleration available.  Doing this gave me piss poor resolutions and 5 FPS at small airports.  And another game wouldn't open at all, and just show the standard "this program can't continue and will be shut down" BS.  I don't know why DXdiag thought I had 9, but I decided to properly dl and install it, and now everything is working fine.  FS has sped up nicely and the other game runs fine without a hitch.  The rest of my computer is a bit slower than Smoke's: 1.2 Celeron and 384 MB PC 133 Ram.  Couldn't hurt.  I was about ready to pull my hair out before upgrading DX.
