For ages I have been trying to get this game to work again and now I'm actually this close as that I can run it.

Still, it isn't very stable and crashes more often than not when flying.

Now I wondered if it would be possible to run it in 3Dfx? Because I can only choose between Software and Direct3D and maybe it runs more stable in 3Dfx mode.
To get it to run I used the info from this site and downloads from this site.
