Out of the box, a few things weren't working for me.
I had to disable shadows, as suggested in one post (see Dear GOG - Dynamic Shadows aren't supposed to be on by Default). They were bad in the original game and still are.
I then set swapinterval to 1 in the .ini to enable Vsync, as suggested in another post (see Vsync doesn't feel like its working right?).
I also had to fiddle with volumes to get a balanced sound, but I worked it out in the end (effects at three quarters, music at one quarter; the voice volume doesn't work).
Other than that, the game worked well (1280 x 1024 on an old 19 inch LCD). It was a joy to play, except, at times, for the crewmates AI on away missions, but that's as it was originally.
One more thing. I installed the mod suggested in yet another post (see HD Mod). It was totally worth it. It makes the game look as good, if not better, than Elite Force II unmodded.
