Thanks to the suggestions last night on Channel 1, hoping to follow up here...
My specs:
Pentium 3 550
384mb RAM (PC100 Crucial)
3DFX Voodoo 5500 (64mb)
DirectX 8.1
Windows 2000 Pro
Running the 3DFX Win2k drivers, I'm seeing 17 to 22 FPS on average.  I run FSAA x 2.  On the Aces High Video Settings, I run 1024 x 768, 32bit color, no mip mapping and unlimited FPS.  Here's a screen shot of what i see in the tower... 
 Any suggested tweaks?  I have downloaded and played with the Omega and x3DFX drivers but didnt see much, if any, gain.  Im kinda hesitant to overclock...
