I know if I leave my Hardware EAX on in Unreal2003 I get around 10 to 20 less FPS, with a couple different drivers. Now is this a Audigy issue or will all EAX sound cards cause big performance hits in games if I enable EAX? I was considering the Turtle Beach Santa Cruz card to replace my Audigy. So do you think the Turtle Beach will have the same performance hits when I turn EAX on?
