I think the X-FI "colored" the sound quite a bit adding its own thing to what ever you pass through it. I dont like that.
But who is doing the rendering of the sound? Is the X-Fi rendering the sound and then passing it to the hdmi output?
What I am trying to get at here is that 3d sound in games is complex. The X-fi is more then just an upgrade for your on boards DAC, it actually has a dsp to offload the 3d sound modeling from the cpu. This can be a pretty heafty process in todays games. If you are simply telling windows to use your video card as a sound source then I fear all the sound modeling is being done on the cpu thus cutting into your performance.
