Well, the Omega driver didn't do the job for me, unfortunately. I've changed MapVisible to 1 as otherwise the game is unplayable - however this is a far from perfect solution as it reveals the entire map.
So this obviously isn't a graphics requirement issue - as has been pointed out above by Pyerun.

Turns out that I needed to upgrade my motherboards BIOS. I also set my voice playback and voice recording to my Soundblaster Live 24. It was previously set to my modem(??).
Not sure what that means, but it hasn't affected my game.
