miles sucks but lots of games use it cause its easier to code for than eax from what i understand.
3d sound is quite taxing on the cpu too. not everyone is lucky like me with an audigy that handles almost all of it
miles sucks. write the developers. quake3 engine does have support for a3d. i remember when carmack decided to use a3d instead of eax.
Course thats 2 years ago eax3 is basically both a3d and eax rolled into 1.
