EF2000 is my all-time flying game. I still play it on DOSBox with my old CH Flightstick.
Ok. Gotta ask:
What on EARTH are you using for a video card?
iirc it was the direct x which prompted me to shelve it. Regardless, at the time I couldn’t find a card that was compatible. I’ve never revisited the matter.
I would LOVE to play again!
