If I had to guess there's only around a ~8ms (125hz standard polling) delay (compared to around ~2ms from a dedicated card) . Without doubt, it's more comparable to a standard USB headset than the apparently glitched XFI go Pro I've used. In any case, I can play with this perfectly fine.
Drivers works pretty well and seem lightweight. If you're using windows 7, you can pop the card in and out without manually switching sources.
If you've used a Xonar this card can pretty much do anything and everything you would expect except being able to change the sample rate.
As Far as SQ goes (No effects). My ears aren't the best, but this seems to be a tad brighter than my MM02 which is known for being a warm DAC/SC. I actually like it better with certain headphones to be completely honest.
Overall, I think it was worth the $33 USD I paid.
If you're gaming, you don't copy files through USB, it's that simple. It's not rocket science for one to realize such basic things.
Dolby headphone? Lol, it's a matter of preference, and honestly I think both CMSS and DH are junk as software surround emulation.
I find it so funny how people are discussing latency about a small form factor USB gaming card, when that's the least important factor, given that there is no realtime recordings going on.
Asus lacks EAX (yes, I went there)(oh right, it has the same EAX support as onboard audio chips) and full OpenAL support, therefore Asus is moot. Is this the point where the thread went? Lame.
EDIT: Given that gaming or competitive gaming isn't made on netbooks, the CPU load subject is near irrelevant.
Games in general lack EAX, but I will admit that creatives FULL desktop DSP aka CA20K2 performs better with certain audio engines.
When did we say Portable = Netbook? Am I not allowed to take this USB sound card and plug it into other desktop computers? The whole reason I said lans was simply because this device will allow me to obtain the same settings/sound through multiple computers without having to mess with a different type of card or the general onboard.
If creatives solution had worked for me, I would recommend both products.
