doesnt sound likely as i used xfi extreme gamer and it did exactly the same
Hi
I have the same card, however i dont think frostbite system works that way, whilst this game has been made for PC it's still the console SKU frostbite (PS3 cell chip was the build standard i think)
They just bolted bits on as it where for the pc, without digging out some old info this could mean that your soundcard is not doing the sound process but the cpu is and it's just telling your sound card what to port, clearly this game sounds amazing but it does for everyone not just those with kick ass sound cards. DICE did a bit on the sound system and how it works a while ago on the blog maybe give better insight. In short i think the engine runs the sound not the sound card.
