Ok, I decided it was about time to worry about that so, here is my pb:
when there's a lot of objects on the screen, for exemple when I'm facing an asteroid field, the sound becomes choppy with craklings, and I have big slow downs, the game is still smooth and all, but it's like everything was slower (including the music). I've tried to fix that by upgrading my video and sound card drivers, but there's nothing to do.
I have an athlon firebird, a sb128 and an Ati Radeon (all in wonder 32 Mo), does someone know an issue with one of these related to fs2, and a way to fix it?.
